Description

Technical Field

[0001] The present application relates to the field of wire winding, and in particular to a winding device for DTY composite wire. Background Art

[0002] DTY composite yarn is an elastic yarn that needs to be wound on a winding roller for storage during production and preparation for easy use and transportation.

[0003] A common winding method is to use a servo motor to drive the winding roller to rotate. As the silk thread wrapped around the winding roller becomes thicker and thicker, each time the servo motor drives the winding roller to rotate one circle, the length of the composite silk thread wound on the winding roller will increase, thereby increasing the winding speed. It is easy for the winding speed to be faster than the speed of producing and preparing the composite silk thread. For this reason, a common solution is to make the winding speed slower than the speed of producing and preparing the composite silk, such as the servo motor constantly adjusting the rotation speed of the winding roller.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: The composite wire is elastic. If the winding speed is slower than the production speed, the composite wire is loosely wound on the winding roller, so that the composite wire cannot be tightly wound on the winding roller, causing the composite wire to easily fall off the winding roller, resulting in poor winding quality of the composite wire, easy falling off during transportation, and easy knotting of the composite wire. Summary of the invention

[0005] In order to improve the problems of poor winding quality, easy falling off during transportation, and easy knotting of composite yarn, the present application provides a winding device for DTY composite yarn.

[0006] The present application provides a winding device for DTY composite yarn adopts the following technical solution: A winding device for DTY composite yarn, comprising: a winding roller for winding the composite yarn; a driving member for driving the winding roller to rotate intermittently through a first transmission member, a second transmission member and a pressure control member in sequence, and the rotation speed of the winding roller is greater than the speed of production and preparation of the composite yarn; wherein the first transmission member is at least used to form a first friction portion; the second transmission member is at least used to form a second friction portion; the first friction portion is at least used to abut against the second friction portion; the pressure control member is used to adjust the pressure between the first friction portion and the second friction portion; when the tension of the winding roller on the composite yarn is greater than a preset tensile force, the first friction portion and the second friction portion slide against each other; when the tension of the winding roller on the composite yarn is equal to the preset tensile force, the first friction portion and the second friction portion rotate synchronously.

[0007] By adopting the above technical solution, when the tension of the winding roller on the composite wire is greater than a preset tensile force, the first friction part and the second friction part slide against each other, then the driving member cannot drive the winding roller to rotate through the first transmission member and the second transmission member, and the winding roller is in a stationary state, so that when the tension on the composite wire is large, the winding roller stops the winding operation, thereby avoiding the situation where the composite wire loses its elasticity due to the large tension, thereby better ensuring the quality of the composite wire after winding. At the same time, the contact between the first friction part and the second friction part is used to realize the driving member driving the winding roller to rotate, then the winding roller will rotate normally, so that the composite wire is normally wound, so the purpose of this application is to normally wind the composite wire roller, and when winding the roller, the tension on the composite wire is equal to the preset tensile force, so that the composite wire is wound under a certain tension. Therefore, it can be ensured that the composite wire is tightly wound on the winding roller, and the composite wire will not be overstretched during the winding process, thereby better ensuring the quality of the composite wire after winding and the quality of the composite wire winding roller after winding.

[0008] Among them, the specific reasons for ensuring the quality of the composite wire roll are as follows: If the composite wire is completely in a relaxed state when winding the composite wire, the composite wire will be very loosely wound on the winding roller, causing the composite wire on the composite wire winding roller to be too loose, which can easily cause the composite wire along the axis of the winding roller to pile up in one direction, resulting in a situation where it is easy to get tangled. The present application allows the composite wire to be wound on the winding roller under the premise of a certain tensile force, so that the composite wire can be wound on the winding roller more compactly, thereby avoiding tangling and improving the quality of the composite wire winding roller.

[0009] Optionally, the first friction parts are arranged in a plurality of circular arrays around a fixed axis, and the second friction parts are arranged in a plurality of circular arrays around the fixed axis; the pressure control member includes an elastic structure, and the elastic structure is used to make the first transmission member and the second transmission member be subjected to an elastic force pressing against each other; the pressure control member also includes an elastic force adjustment structure, and the elastic force adjustment structure is used to increase or decrease the elastic force.

[0010] By adopting the above-mentioned technical solution and utilizing the setting of the elastic structure and the elastic force adjustment structure, the contact force between the first friction part and the second friction part can be adjusted, so that the friction force between the first friction part and the second friction part can be adjusted, so that when the driving member drives the winding roller to rotate through the first transmission member and the second transmission member, the tensile force of the wire on the winding roller when the first transmission member and the second transmission member slide against each other can be adjusted. In some cases, when the composite wire is used to sew the bottom edge of clothes, the composite wire needs to have very good elasticity. At this time, the pressure between the first friction part and the second friction part can be reduced, thereby reducing the friction force. At this time, after the composite wire is wound on the winding roller, the tensile force of the composite wire is reduced, so that the degree of stretching of the composite wire is greatly reduced, and a composite wire with good elasticity and almost no stretching is obtained. In other cases, the composite thread is used to sew the middle part of clothes when in use. The composite thread does not need to have very good elasticity, so the pressure between the first friction part and the second friction part can be increased. After the composite thread is wound on the winding roller, the tensile force applied to the composite thread is relatively large, and the composite thread will be stretched and deformed, so that the composite thread will lose part of its elasticity, and retain part of its elasticity. It is better to obtain composite thread rollers with different elasticity according to usage requirements, which not only ensures the quality of the composite thread roller, but also improves the diversity of the elasticity of the composite thread.

[0011] Optionally, the winding equipment also includes: a wire stretching detection device, which is used to detect the tension of the composite wire applied to the winding roller; when the wire stretching detection device detects that the tension of the composite wire applied to the winding roller is greater than the preset tension force, the elastic force adjustment structure reduces the elastic force and\or the driving device reduces the winding speed of the winding roller.

[0012] By adopting the above technical solution, when the tension of the composite wire is relatively large, the composite wire will be stretched after being wound on the winding roller, causing the composite wire to lose some elasticity. Then, by using the wire stretching detection component, when the tension of the wire is relatively large, the rotation speed of the winding roller is reduced, thereby reducing the tension on the wire and better protecting the elasticity of the wire. Thus, a composite wire roller with a specified elasticity can be obtained.

[0013] Optionally, the winding device also includes: a stretching member for directly or indirectly stretching the composite wire so that the tension between the composite wire and the winding roller is equal to the preset stretching force; the driving member is used to drive the winding roller to rotate when the stretching member causes the composite wire to be subjected to the tension of the winding roller equal to the preset stretching force.

[0014] By adopting the above-mentioned technical solution, the stretching member makes the tension between the composite wire and the winding roller equal to the preset tension. At this time, the driving member drives the winding roller to rotate, so that the composite wire can be wound on the winding roller with a specified degree of tension, and a composite wire roller with a specified degree of elasticity can be better obtained.

[0015] Optionally, an injection channel is formed in the first transmission member, and an elastic chamber connected to the injection channel is formed in the first friction part; the first friction part can be deformed to make the first friction part relatively larger or smaller; a movable plate is provided in the injection channel, and the movable plate is used to close the injection channel; the elastic structure is used to apply an elastic force to the movable plate that can increase or decrease the pressure of the injection channel; and the elastic force adjustment structure is used to increase or decrease the elastic force.

[0016] By adopting the above technical solution, the first friction part and the second friction part are brought into contact by filling the elastic chamber with liquid to expand the first friction part. Then, after a long period of use, when the second friction part is damaged and the first friction part and the second friction part cannot slide against each other, the first friction part will be squeezed to disappear, that is, the moving plate in the injection cavity moves away from the first friction part, so that the liquid in the elastic chamber flows outward, and after the first friction part disappears, there is no friction between the first friction part and the second friction part, so that the first friction part and the second friction part can slide normally. Since there are multiple first friction parts and second friction parts, the main purpose is that when one of the second friction parts is damaged, the mutual sliding and synchronous rotation between the first friction part and the second friction part can still proceed normally, avoiding the situation where the second friction part is suddenly damaged and affects the winding of the composite wire.

[0017] Optionally, the wire stretching detection component includes: a carrier, a first guide roller, a second guide roller and a shifting elastic member; the composite wire is connected to the winding roller after passing around the first guide roller and the second guide roller; the shifting elastic member is used to carry the first guide roller to a first position; when the tension of the winding roller on the composite wire is less than the preset stretching force, the first guide roller is located at the first position; when the tension of the winding roller on the composite wire is equal to the preset stretching force, the composite wire exerts pressure on the first guide roller to move the first guide roller to a second position located on the side of the first position; when the tension of the winding roller on the composite wire is greater than the preset stretching force, the composite wire exerts pressure on the first guide roller to move the first guide roller to a third position located on the side of the second position; when the first guide roller is located at the first position, the driving member stops driving the winding roller to rotate; when the first guide roller is located at the second position, the driving member drives the winding roller to rotate; when the first guide roller is located at the third position, the first friction portion and the second friction portion slide against each other.

[0018] By adopting the above-mentioned technical scheme, the shifting elastic member will apply an elastic force to the first guide roller, so that the first guide roller is located in the first position, but after the composite wire passes around the first guide roller, the first guide roller will be subjected to the pulling force of the composite wire, thereby generating pressure on the first guide roller, which will cause the first guide roller to move to the second position or the third position. When the pulling force exerted on the composite wire is the same as the preset tensile force, the first guide roller moves to the second position, otherwise it moves to the third position, so that the degree of pulling force exerted on the composite wire can be better obtained by detecting the position of the first guide roller, thereby better ensuring that the pulling force exerted on the composite wire is the same as the preset pulling force, thereby better controlling the elasticity of the composite wire after it is wound on the winding roller, and being able to retain the application elasticity of the composite wire for a long time. When the first guide roller is in the first position, the driving member will not cause the winding roller to rotate, thereby preventing the composite wire from being too loose and easily tangled when wound on the winding roller and easily falling off relative to the winding roller. When the first guide roller is in the third position, the driving member, the first friction portion and the second friction portion slide against each other, so that when the tension applied to the composite wire is greater than the preset tensile force, the winding roller will not rotate, thereby preventing the composite wire from being wound on the winding roller with excessive tension, thereby better controlling the composite wire after being wound on the winding roller and retaining the elasticity of the composite wire for a long time.

[0019] Optionally, the stretching member includes a stretching power structure and / or a third driving roller; the stretching power structure is used to drive the second guide roller to move away from the first guide roller; and / or drive the winding roller to move away from the conveying direction of the composite wire; and / or drive the third guide roller to move; the composite wire is partially in contact with the third guide roller, and the movement of the third guide roller can cause the composite wire to be stretched.

[0020] By adopting the above technical solution, the composite wire is in contact with the third guide roller, and the movement of the third guide roller will generate tension on the composite wire, and the composite wire is stretched. Then, when the first guide roller is in the first position, the third guide roller moves, and the first guide roller can be moved to the second position. Then, at this time, the tension on the composite wire is equal to the preset tensile force, and the winding roller winds the composite wire again. At the same time, the winding roller can be moved away from the first guide roller to increase the tension on the composite wire to equal the preset tensile force. Then, when the tensile force on the composite wire is small, the composite wire is wound on the winding roller after the tension on the composite wire is increased by the above method. After the composite wire is wound on the winding roller, the elasticity of the composite wire can be better controlled and retained for a long time.

[0021] Optionally, the elastic structure includes an elastic airbag, which is arranged in the injection cavity and fixed to the movable plate; the elastic force adjustment structure includes an air injection tube and an air pump; the air injection tube is connected to the elastic airbag, and the air pump injects external air into the elastic airbag to expand and contract the elastic airbag; when the elastic airbag expands, the elastic force applied by the elastic airbag on the movable plate increases; when the elastic airbag contracts, the elastic force applied by the elastic airbag on the movable plate decreases.

[0022] By adopting the above technical solution, the elastic airbag exerts an elastic force on the movable plate, so that the elastic chamber is filled with liquid, that is, the first friction part expands. The degree of expansion of the elastic airbag can be controlled by the air pump and the air injection tube, so that the elastic force exerted by the elastic airbag on the movable plate can be increased or decreased, and the force required for the deformation of the first friction part can be changed, thereby adjusting the relationship between the timing of slippage between the driving member and the winding roller and the tension of the composite wire on the winding roller, so that when the first friction part and the second friction part slip, the first guide roller can be prevented from moving to the side of the third position, so that the maximum tension of the composite wire can be better controlled at all times, and the elasticity of the composite wire application can be better retained for a long time.

[0023] Optionally, when the first transmission part and the second transmission part slide with each other and the first guide wheel is located to the side of the third position, the air pump contracts the elastic airbag through the air injection tube; when the first transmission part and the second transmission part slide with each other and the first guide wheel is located at the third position, the elastic airbag stops contracting; the winding equipment also includes: a position detection part and a control part; the position detection part is used to detect the first position, the second position and the third position of the first transmission wheel; the control part is used to connect the position detection part with the driving part and the air pump.

[0024] Optionally, the second transmission member is a lightweight aluminum shell; the lightweight aluminum shell forms the slot; and the winding roller is fixed to the second transmission member.

[0025] By adopting the above technical solution, since the first friction part and the second friction part will slip, and the first friction part and the second friction part are both provided in plurality, when the first friction part and the second friction part slip against each other and pass over each other, there will be some positions where the first friction part cannot contact the second friction part. Therefore, if the second transmission part is heavy at this time, there will be a large rotational inertia, which may cause the rotational inertia of the second transmission part and the winding roller to cause the tension on the composite wire to be greater than the preset tensile force. The use of a lightweight aluminum shell can reduce the weight, thereby reducing the inertia, and avoiding the situation where the rotational inertia causes the tension on the composite wire to be greater than the preset tensile force.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The first friction part and the second friction part slide against each other and the winding roller rotates at a speed greater than the production speed of the composite wire, so that the composite wire can be wound tightly on the winding roller. Since the first friction part and the second friction part slide against each other, when the composite wire is subjected to a large tension, the winding roller stops the winding operation, thereby preventing the composite wire from being subjected to a large tension and causing the composite wire to lose its elasticity, better ensuring the quality of the composite wire after winding, and avoiding the problem of loose winding and over-tight winding; 2. By controlling the friction force between the first friction part and the second friction part through the pressure control part, it can be achieved that the driving part drives the winding roller to rotate through the first transmission part and the second transmission part, so that the maximum tension applied by the winding roller to the composite wire can be adjusted by the pressure control part, thereby better adjusting the load wound on the winding roller according to the performance of the composite wire and better regulating the quality of the composite wire roller.

[0029] The following is combined with Figure 1-19 This application is described in further detail.

[0030] The embodiment of the present application discloses a winding device for DTY composite yarn. Example

[0031] Refer to the attached Figure 1-5 A winding device for DTY composite yarn includes: a winding roller 1, a driving member 2, a first transmission member 3, a second transmission member 4 and a pressure control member 95.

[0032] The winding roller 1 is used for winding the composite wire. The driving member 2 is used to drive the winding roller 1 to rotate intermittently through the first transmission member 3, the second transmission member 4 and the pressure control member 95 in sequence. The rotation speed of the winding roller 1 is greater than the speed of production and preparation of the composite wire. The first transmission member 3 is at least used to form the first friction part 31; the second transmission member 4 is at least used to form the second friction part 41; the first friction part 31 is at least used to abut against the second friction part 41. The pressure control member 95 is used to adjust the pressure between the first friction part 31 and the second friction part 41. When the tension of the composite wire on the winding roller 1 is greater than a preset tensile force, the first friction part 31 and the second friction part 41 slide against each other. When the tension of the composite wire on the winding roller 1 is equal to the preset tensile force, the first friction part 31 and the second friction part 41 rotate synchronously. In this embodiment, the first friction part 31 and the second friction part 41 are both plates, and the driving member 2 adopts a driving motor 21. The driving member 2 drives the first friction part 31 to rotate, the first friction part 31 drives the second friction part 41 to rotate, and the second friction part 41 drives the winding roller 1 to rotate, so as to wind the composite wire on the winding roller 1. The pressure control member 95 adopts a cylinder in this embodiment, wherein the pressure control member 95 presses on the first friction part 31 or the second friction part 41, which increases and decreases the pressure between the first friction part 31 and the second friction part 41. Preferably, a universal ball is arranged at the output end of the driving cylinder, and the pressure control member 95 presses on the first friction part 31 or the second friction part 41 through the universal ball, which can ensure the normal rotation between the first friction part 31 and the second friction part 41.

[0033] By adopting the above technical solution, when the tension of the winding roller 1 on the composite wire is greater than a preset tensile force, the first friction part 31 and the second friction part 41 slide against each other, then the driving member 2 cannot drive the winding roller 1 to rotate through the first transmission member 3 and the second transmission member 4, and the winding roller 1 is in a stationary state. Therefore, when the tension on the composite wire is large, the winding roller 1 stops the winding operation, thereby avoiding the situation where the composite wire loses its elasticity due to the large tension, thereby better ensuring the quality of the composite wire after winding. At the same time, the contact between the first friction part 31 and the second friction part 41 is used to realize that the driving member 2 drives the winding roller 1 to rotate, then the winding roller 1 will rotate normally, so that the composite wire is normally wound, so the purpose of this application is to normally wind the composite wire, and when winding, the tension on the composite wire is equal to the preset tensile force, so that the composite wire is wound under a certain tension. Therefore, it can be ensured that the composite wire is wound tightly around the winding roller, and the composite wire will not be overstretched during the winding process, thereby better ensuring the quality of the composite wire after winding and the quality of the composite wire winding roller after winding.

[0034] Among them, the specific reasons for ensuring the quality of the composite wire roll are as follows: If the composite wire is completely in a relaxed state when winding the composite wire, the composite wire will be very loosely wound on the winding roller, causing the composite wire on the composite wire winding roller to be too loose, which can easily cause the composite wire along the axis of the winding roller to pile up in one direction, resulting in a situation where it is easy to get tangled. The present application allows the composite wire to be wound on the winding roller under the premise of a certain tensile force, so that the composite wire can be wound on the winding roller more compactly, thereby avoiding tangling and improving the quality of the composite wire winding roller.

[0035] In some other solutions, another solution about the first transmission member 3 and the second transmission member 4 is as follows, specifically the second solution: See attached Figure 6 , 16, the first friction part 31 is arranged in a plurality of circular arrays around a fixed axis, and the second friction part 41 is arranged in a plurality of circular arrays around the fixed axis. The fixed axis is the axis of the winding roller 1. The first transmission member 3 and the second transmission member 4 are both plate bodies, the first friction part 31 is a spherical structure protruding outward formed on the first transmission member 3, and the second friction part 41 is a spherical structure protruding outward formed on the second transmission member 4. The first friction part 31 and the second friction part 41 are interlaced and buckled with each other, and when the driving member 2 drives the first transmission member 3 to rotate, the second transmission member 4 and the winding roller 1 are driven to rotate through the first friction part 31 and the second friction part 41.

[0036] See attached Figure 5 , 16 The pressure control member 95 includes an elastic structure 51, and the elastic structure 51 is used to make the first transmission member 3 and the second transmission member 4 subject to an elastic force that presses against each other. The pressure control member 95 also includes an elastic force adjustment structure 52, and the elastic force adjustment structure 52 is used to increase or decrease the elastic force.

[0037] See attached Figure 1-5, 16, a specific solution of this embodiment is that the output end of the driving member 2 is connected to the first transmission member 3 through a rotating shaft 22, wherein a slide groove is provided on the rotating shaft 22, and the first transmission member 3 is slidably connected with the slide groove, that is, the first transmission member 3 moves relative to the axis of the rotating shaft 22, and the rotation of the rotating shaft 22 drives the first transmission member 3 to rotate. The axis of the rotating shaft 22 coincides with the axis of the winding roller 1, and the second transmission member 4 is installed on the winding roller 1. The elastic control structure includes a first spring 511 and an abutment plate 512, the abutment plate 512 is fixed to the rotating shaft 22, and the first spring 511 is arranged between the abutment plate 512 and the first transmission member 3. Then, the first transmission member 3 will be close to the second transmission member 4 under the action of the first spring 511, so that the first friction portion 31 and the second friction portion 41 are interlaced and buckled together. When the first transmission member 3 rotates, the first friction portion 31 and the second friction portion 41 contact, so that the second friction portion 41 drives the second transmission member 4 to rotate. Then, when the composite wire on the winding roller 1 is subjected to a large tensile force, that is, the composite wire is produced outward. When the production speed is less than the speed at which the winding roller 1 winds the composite wire, the first friction portion 31 will move away from the second friction portion 41, and the first spring 511 will be compressed, so that the first friction portion 31 passes over the second friction portion 41. After passing over the second friction portion 41, the first friction portion 31 is again engaged with the second friction portion 41 under the action of the first spring 511, so that the first friction portion 31 can reciprocately pass over the second friction portion 41, that is, the first friction portion 31 and the second friction portion 41 slip, to avoid the composite wire being wound around the winding roller 1 with a large tensile force, thereby better ensuring the elasticity of the composite wire.

[0038] See attached Figure 1-19 Another specific solution is that the abutment plate 512 is slidably connected to the rotating shaft 22, and the elastic force adjustment structure 52 is an electric rod. The electric rod drives the abutment plate 512 to move, so that the degree of compression of the first spring 511 changes, so that the elastic force of the first spring 511 on the abutment plate 512 changes. The abutment force between the first friction part 31 and the second friction part 41 is adjusted. It can be adjusted according to the requirements of different elasticity of the composite wire, that is, when the first friction part 31 and the second friction part 41 slip, the tensile force on the composite wire becomes larger or smaller, so as to better protect the elasticity of the composite wire.

[0039] In some other solutions, other solutions about the first transmission member 3 and the second transmission member 4 are as follows, specifically the third solution: See attached Figure 17-18, a liquid injection channel 513 is formed in the first transmission member 3, and an elastic chamber connected to the liquid injection channel 513 is formed in the first friction part 31. The first friction part 31 can be deformed so that the first friction part 31 becomes relatively larger or smaller. A movable plate 514 is provided in the liquid injection channel 513, and the movable plate 514 is used to close the liquid injection channel 513. The elastic structure 51 is used to apply an elastic force to the movable plate 514 that can increase or decrease the pressure of the liquid injection channel 513; the elastic force adjustment structure 52 is used to increase or decrease the elastic force.

[0040] See attached Figure 13-14 In a specific solution, the driving member 2 is connected to the first transmission member 3 by flexible transmission, and flexible transmission refers to pulley transmission or sprocket transmission. The first transmission member 3 is a cylindrical rod body, and a fixed frame 11 is provided to support the first transmission member 3 and the driving member 2. The first transmission member 3 and the fixed frame 11 are rotatably connected. The injection cavity 513 is a main cavity 513A and a plurality of sub-cavities 513B connected to the main cavity 513A. The first friction part 31 is a flexible material fixed to the first transmission member 3, and the flexible material can be a rubber film. The first friction part 31 covers a sub-cavity 513B, so that the liquid in the injection cavity 513 will enter the elastic chamber to expand the first friction part 31, and the degree of expansion of the first friction part 31 is adjusted by using the different pressures in the injection cavity 513. At this time, the first friction part 31 is formed at the end of the first transmission member 3.

[0041] In another specific scheme, the first friction portion 31 is formed on the side of the first transmission member 3, the second transmission member 4 is an annular plate body, and the second friction portion 41 is formed in the inner ring of the annular plate body, so that the first transmission member 3 is inserted into the second transmission member 4 to achieve contact between the first friction portion 31 and the second friction portion 41.

[0042] In some other solutions, the first friction part 31 is a rigid structure, a liquid injection cavity 513 is formed in the first transmission member 3, a plurality of sub-cavities 513B are opened on the side of the first transmission member 3, the first friction part 31 is inserted into the sub-cavity 513B, and liquid is injected into the liquid injection cavity 513. The first transmission member 3 is inserted into the second transmission member 4 so that the first friction part 31 and the second friction part 41 are in contact.

[0043] In this embodiment, one specific solution for the elastic structure 51 and the elastic force adjustment structure 52 is as follows: The elastic structure 51 is a combination of a plate and a second spring 515, and the elastic force adjustment structure 52 is an electric push rod or a cylinder used to push the plate to move. The second spring 515 is in contact with the moving plate 514, and the elastic force adjustment structure 52 pushes the plate to compress the second spring 515, so that the elastic force applied by the elastic structure 51 to the moving plate 514 can be adjusted.

[0044] Another specific solution of the elastic structure 51 and the elastic force adjustment structure 52 is as follows, specifically the second solution: Refer to the attached Figure 13-14 , 17-18, the elastic structure 51 includes an elastic airbag 516, which is arranged in the injection cavity 513, and the elastic airbag 516 is fixed to the movable plate 514. The elastic force adjustment structure 52 includes an air injection pipe 521 and an air pump 522. The air pump 522 is fixed on the fixed frame 11. The air injection pipe 521 is connected to the elastic airbag 516, and the air pump 522 injects external air into the elastic airbag 516 to expand and contract the elastic airbag 516. When the elastic airbag 516 expands, the elastic force applied by the elastic airbag 516 to the movable plate 514 increases. When the elastic airbag 516 contracts, the elastic force applied by the elastic airbag 516 to the movable plate 514 decreases. Then the elastic force applied by the elastic structure 51 to the movable plate 514 can be adjusted.

[0045] In some other solutions, the elastic airbag 516 can be replaced by an elastic rubber body, an elastic pad, or air is filled between the moving plate 514 and the above-mentioned plate body.

[0046] This embodiment specifically utilizes the setting of the elastic structure 51 and the elastic force adjustment structure 52 to adjust the contact force between the first friction part 31 and the second friction part 41, so that the friction force between the first friction part 31 and the second friction part 41 can be adjusted, so that when the driving member 2 drives the winding roller 1 to rotate through the first transmission member 3 and the second transmission member 4, the tensile force of the wire on the winding roller 1 when the first transmission member 3 and the second transmission member 4 slide against each other can be adjusted. If the first transmission member 3 and the second transmission member 4 slide against each other, the winding roller 1 will wind the composite wire, but because the composite wire has been stretched, it cannot be wound on the winding roller 1. At this time, the tension on the composite wire is related to the slippage of the first transmission rod and the second transmission member 4. It can be imagined that: one end of a wire is fixed, and the other end is fixed to the winding roller 1, and the winding roller 1 rotates, the wire is straightened and has no extra length, so the wire cannot be wound around the winding roller 1, the first transmission member 3 and the second transmission member 4 slip against each other, and the wire is subjected to tension. If the friction between the first transmission rod and the second transmission member 4 is reduced, the reaction force applied by the winding roller 1 to the second transmission member 4 is reduced, that is, the tension on the wire is reduced. To this end, by controlling the magnitude of the friction between the first friction part 31 and the second friction part 41 so that the tension on the winding roller 1 applied to the composite wire increases or decreases when the two slip.

[0047] In some cases, when the composite thread is used to sew the bottom edge of clothes, the composite thread needs to have very good elasticity. In this case, the pressure between the first friction part 31 and the second friction part 41 can be reduced, thereby reducing the friction force. At this time, after the composite thread is wound on the winding roller 1, the tensile force of the composite thread is reduced, so that the degree of stretching of the composite thread is greatly reduced, and a composite thread with good elasticity and almost no stretching is obtained. In other cases, when the composite thread is used to sew the middle part of clothes, the composite thread does not need to have very good elasticity. In this case, the pressure between the first friction part 31 and the second friction part 41 can be increased. Then, after the composite thread is wound on the winding roller 1, the tensile force on the composite thread is relatively large, and the composite thread will be stretched and deformed, so that the composite thread will lose some elasticity and retain some elasticity. It is better to obtain composite thread rollers with different elasticity according to the use requirements, which not only ensures the quality of the composite thread roller, but also improves the diversity of the elasticity of the composite thread.

[0048] By adopting the above technical solution, the first friction part 31 and the second friction part 41 are brought into contact by filling the elastic chamber with liquid to expand the first friction part 31. Then, after a long period of use, when the second friction part 41 is damaged and the first friction part 31 and the second friction part 41 cannot slide against each other, the first friction part 31 will be squeezed to disappear, that is, the moving plate 514 in the injection cavity 513 moves away from the first friction part 31, so that the liquid in the elastic chamber flows outward, so that after the first friction part 31 disappears, there is no friction between the first friction part 31 and the second friction part 41, so that the first friction part 31 and the second friction part 41 can slide normally. Since there are multiple first friction parts 31 and second friction parts 41, the main purpose is that when one of the second friction parts 41 is damaged, the mutual sliding and synchronous rotation between the first friction part 31 and the second friction part 41 can still be carried out normally, avoiding the situation where the second friction part 41 is suddenly damaged and affects the winding of the composite wire. Example

[0049] The difference from Example 1 is that: The winding device further includes: a wire stretching detection member 6, which is used to detect the tension of the composite wire on the winding roller 1. When the wire stretching detection member 6 detects that the tension of the composite wire on the winding roller 1 is greater than the preset tension, the elastic force adjustment structure 52 reduces the elastic force and\or the driving member 2 reduces the winding speed of the winding roller 1.

[0050] The specific scheme of the wire stretching detection member 6 in this embodiment is: Refer to the attached Figure 6 A plurality of first protruding plates 61 are formed on the winding roller 1, and a second transmission member 4 is sleeved on the winding roller 1 and a plurality of second protruding plates 62 are formed on the second transmission member 4. The first protruding plates 61 and the second protruding plates 62 are in contact with each other, and a pressure sensor is arranged between the first protruding plates 61 and the second protruding plates 62. The pressure sensor can obtain the force of the second transmission member 4 driving the winding roller 1 to rotate, that is, the pulling force of the winding roller 1 on the composite wire.

[0051] When the tension of the composite wire is relatively large, the composite wire will be stretched after being wound on the winding roller 1, causing the composite wire to lose some of its elasticity. Then, the wire stretching detection member 6 is used to reduce the rotation speed of the winding roller 1 after the tension of the wire is relatively large, thereby reducing the tension on the wire and better protecting the elasticity of the wire. Thus, a composite wire roller with a specified degree of elasticity can be better obtained. The composite wire loses some of its elasticity when the first transmission member 3 and the second transmission member 4 slip and the composite wire is subjected to excessive tension, causing the stretched part of the composite wire to lose its elasticity. However, the composite wire produced later will not lose its elasticity if it is not subjected to excessive tension, thereby causing the composite wire to lose some of its elasticity. Example

[0052] The difference from Example 2 is that: Since the first friction part 31 and the second friction part 41 are staggered, after the first friction part 31 and the second friction part 41 slip, one of the first friction parts 31 actually passes over the second friction part 41 in contact with the first friction part 31, and reaches the position of the other second friction part 41, and contacts the second friction part 41. Then, after the first friction part 31 passes over the second friction part 41, since the winding roller 1 stops rotating for a short time, but the speed at which the composite wire is produced outward is constant, the composite wire is relaxed at this time, and the winding roller 1 does not apply tension to the composite wire. At this time, when the winding roller 1 rotates again, the composite wire is wound without tension, which easily causes the composite wire to be too loose when wound on the winding roller 1, and it is easy to get knotted and the composite wire is easy to fall off.

[0053] Refer to the attached Figure 13-15 In order to solve the above problems, the winding device of this embodiment further includes: a stretching member 7 for directly or indirectly stretching the composite wire so that the tension between the composite wire and the winding roller 1 is equal to the preset tension. The driving member 2 is used to drive the winding roller 1 to rotate when the tension member 7 causes the composite wire to be subjected to the tension of the winding roller 1 equal to the preset tension.

[0054] Among them, the specific scheme of the stretching member 7 is as follows: the stretching member 7 includes a stretching power structure 71, the stretching power structure 71 is a mobile frame 72, the mobile frame 72 is slidably connected to the fixed frame 11, the driving member 2, the first transmission member 3, the second transmission member 4, the pressure control member 95 and the winding roller 1 are all arranged on the mobile frame 72, the mobile frame 72 drives the winding roller 1 to move, so that the winding tube is away from the direction of the composite wire conveying, and the direction away from the composite wire refers to the direction in which the winding roller 1 moves and the composite wire is straightened, and then the pressure sensor in Example 2 will display the corresponding pressure value, and when the pressure value matches the preset tensile force, the driving member 2 starts to drive the winding roller 1 to rotate. Then the mobile frame 72 is gradually reset under the premise of keeping the value on the pressure sensor matching the preset tensile force, so that the reciprocating repetition of this step can increase the tensile force on the composite wire when the tensile force on the composite wire is small, so that the composite wire is better wound on the winding roller 1. Thereby, the composite wire can be wound on the winding roller 1 with a specified tension degree, and a composite wire roller with a specified elasticity degree can be better obtained.

[0055] The moving frame 72 is driven by a pushing component to move the moving frame 72. The pushing component is one of an electric push rod, a cylinder, a hydraulic cylinder and a screw nut pair. Example

[0056] The difference from Example 2 is that: See attached Figure 3 , 8 -9, the pressure sensor is replaced by a combination of a support frame 63, a first guide roller 64, a second guide roller 65 and a shift elastic member 66. The second guide roller 65 is rotatably connected to the support frame 63.

[0057] The support frame 63 is fixed to the fixed frame 11, and the line between the axis of the first guide roller 64 and the axis of the second guide roller 65 is inclined relative to the straightened composite wire, preferably forming an angle of 10-20°.

[0058] The composite wire is connected to the winding roller after passing through the first guide roller 64 and the second guide roller 65. The shifting elastic member 66 is used to carry the first guide roller 64 to a first position. The shifting elastic member 66 includes: a guide rod 661, a sliding block 662 and a third spring 663. The guide rod 661 is fixed to the support frame 63. The sliding block 662 is slidably connected to the guide rod 661. The third spring 663 is arranged between the sliding block 662 and the support frame 63. A limit plate is arranged on the guide rod 661. The limit plate prevents the sliding block 662 from sliding outward on the guide rod 661. The first guide roller 64 is installed on the sliding block 662, and the first guide roller 64 is rotatably connected to the sliding block 662. The extension direction of the guide rod 661 forms an angle of 0-20° when the composite wire is straightened, preferably 0°, so that the extension direction of the guide rod 661 is parallel to the composite wire when it is straightened, wherein the composite wire will be connected to the winding roller 1 only after it passes through the second guide roller 65 and the first guide roller 64 in sequence, then when the winding roller 1 pulls the composite wire hard, the composite wire will drive the first guide roller 64 to move, that is, the sliding block 662 moves on the guide rod 661, and the third spring 663 is compressed. Therefore, the magnitude of the tensile force on the composite wire is related to the position of the first guide roller 64.

[0059] Specifically, when the tension of the winding roller 1 on the composite wire is less than the preset tensile force, the first guide roller 64 is located at the first position. When the tension of the winding roller 1 on the composite wire is equal to the preset tensile force, the composite wire exerts pressure on the first guide roller 64 to move the first guide roller 64 to a second position located on the side of the first position. When the tension of the winding roller 1 on the composite wire is greater than the preset tensile force, the composite wire exerts pressure on the first guide roller 64 to move the first guide roller 64 to a third position located on the side of the second position. The tension of the winding roller 1 on the composite wire is greater than the preset tensile force by a small margin, and when the tension of the winding roller 1 on the composite wire is greater than the preset tensile force by a large margin, the first guide roller 64 moves to the side of the third position. When the first guide roller 64 is located at the first position, the driving member 2 stops driving the winding roller 1 to rotate, and the tensile power structure 71 drives the moving frame 72 to move. When the first guide roller 64 is located at the second position, the driving member 2 drives the winding roller 1 to rotate. When the first guide roller 64 is located at the third position, the driving member 2 drives the first transmission member 3 and the second transmission member 4 to rotate, but the first friction portion 31 and the second friction portion 41 slide against each other, and the winding roller 1 stops rotating.

[0060] A camera is provided on the fixing frame 11, and the camera is used to identify the first position, the second position, and the third position of the first guide roller 64. In some other schemes, a rangefinder is provided on the fixing frame 11, and the rangefinder measures the distance information obtained after the first guide roller 64 moves, so as to identify the first position, the second position, and the third position of the first guide roller 64. Alternatively, a pressure sensor is provided on the bearing frame 63, and the pressure sensor is used to abut against the third spring 663, and the first position, the second position, and the third position of the first guide roller 64 are identified according to the value on the pressure sensor.

[0061] The shifting elastic member 66 will apply an elastic force to the first guide roller 64, so that the first guide roller 64 is located in the first position. However, after the composite wire passes around the first guide roller 64, the first guide roller 64 will be subjected to the pulling force of the composite wire, thereby generating pressure on the first guide roller 64, which will cause the first guide roller 64 to move to the second position or the third position. When the pulling force exerted on the composite wire is the same as the preset tensile force, the first guide roller 64 moves to the second position, otherwise it moves to the third position. Therefore, the degree of pulling force exerted on the composite wire can be better obtained by detecting the position of the first guide roller 64, thereby better ensuring that the pulling force exerted on the composite wire is the same as the preset pulling force, thereby better controlling the elasticity of the composite wire after it is wound on the winding roller 1, and being able to retain the application elasticity of the composite wire for a long time. When the driving member 2 is in the first position when the first guide roller 64 is in the first position, the winding roller 1 will not be rotated, thereby preventing the composite wire from being too loose and easily tangled when wound on the winding roller 1 and easily falling off relative to the winding roller 1. When the driving member 2 is in the third position when the first guide roller 64 is in the third position, the first friction portion 31 and the second friction portion 41 slide against each other, so that when the tension applied to the composite wire is greater than the preset tensile force, the winding roller 1 does not rotate, so that the composite wire will not be wound on the winding roller 1 with excessive tension, thereby better controlling the composite wire after being wound on the winding roller 1 and retaining the elasticity of the composite wire for a long time. Example

[0062] The difference from Example 4 is that: When the first transmission part and the second transmission part slide against each other and the first guide wheel is located at the side of the third position, the air pump 522 shrinks the elastic airbag 516 through the air injection pipe 521; when the first transmission part and the second transmission part slide against each other and the first guide wheel is located at the third position, the elastic airbag 516 stops shrinking. The purpose of shrinking the elastic airbag 516 is to prevent the winding roller 1 from applying too much tension to the composite wire when the first friction part 31 and the second friction part 41 slip.

[0063] The winding device further includes: a position detection member 8 and a control member 9; the position detection member 8 is used to detect the first position, the second position and the third position of the first transmission wheel; the control member 9 is used to connect the position detection member 8 with the driving member 2 and the air pump 522. The position detection member 8 can be a camera, a rangefinder or a pressure sensor in Example 4.

[0064] The control component 9 is used to establish a signal connection. For example, when the position detection component 8 adopts a pressure sensor, the control component 9 includes a signal generating element, a signal sending element, a first signal receiving element, a second signal receiving element and a third signal receiving element. The signal generating element is used to generate a first signal that the first guide roller 64 is located at the first position, a second signal that the first guide roller 64 is located at the second position, a third signal that the first guide roller 64 is located at the third position and a fourth signal that the first guide roller 64 is located to the side of the third position according to the pressure sensor. The signal sending element is used to send the first signal, the second signal, the third signal and the fourth signal to the first signal receiving element, the second signal receiving element and the third signal receiving element.

[0065] The first signal receiving element is disposed on the circuit control board of the stretching power structure 71. After the first signal receiving element receives the first signal, the stretching power structure 71 drives the moving frame 72 to move on the fixed frame 11, so that the tension of the composite wire on the winding roller 1 increases to the preset tension. After the first signal receiving element receives the second signal, the stretching power structure 71 stops driving the moving frame 72 to move.

[0066] The second signal receiving element is arranged on the circuit control board of the driving motor 21, and when the second signal receiving element receives the second signal and the third signal, the driving motor 21 drives the winding roller 1 to rotate, and when receiving the first signal and the fourth signal, the driving motor 21 stops.

[0067] The third signal receiving element is disposed on the circuit control board of the air pump 522, and when the third signal receiving element receives the fourth signal The signal sending element sends the second signal to the second signal receiving element. When the second signal receiving element receives the fourth signal, the air pump 522 shrinks the elastic airbag 516 through the air injection tube 521. When the second signal receiving element receives the first signal, the second signal or the third signal, the air pump 522 stops.

[0068] Another specific solution for the position detection element 8 and the control element 9 is: Refer to the attached Figure 9-12The position detection member 8 includes: a bending rod 81 and a first battery cell 82. The control member 9 includes: an installation box 91, a second battery cell 92, a third battery cell 93 and a fourth battery cell 94. The installation box 91 is filled with fluorine liquid. The second battery cell 92 is used to power the pushing member, the third battery cell 93 is used to power the driving motor 21, and the fourth battery cell 94 is used to power the air pump 522. The first battery cell 82 is used to connect to an external power source.

[0069] The second battery cell 92, the third battery cell 93 and the fourth battery cell 94 are arranged in the installation box 91 and form a conductive rod arranged along an axis. The fluorinated liquid immerses the second battery cell 92, the third battery cell 93 and the fourth battery cell 94. There is a gap between the second battery cell 92, the third battery cell 93 and the fourth battery cell 94, and the gap is filled with a non-conductor. The first battery cell 82 is used to contact the conductive rod.

[0070] The positions of the second battery cell 92, the third battery cell 93 and the fourth battery cell 94 on the distribution pole are arranged from top to bottom. One end of the bending rod 81 is connected to the sliding block 662, and the other end is inserted into the installation box 91. When the sliding block 662 is in the first position, the first battery cell 82 is in contact with the second battery cell 92. When the sliding block 662 is in the second position and the third position, the first battery cell 82 is in contact with the third battery cell 93. When the sliding block 662 is located to the side of the third position, the first battery cell 82 is in contact with the fourth battery cell 94. The side refers to the side along one direction, such as the bottom along the downward direction and the right along the right direction.

[0071] Thus, when the sliding block 662 moves to different positions, the first battery cell 82 supplies power to one of the pushing component, the driving motor 21 and the air pump 522 .

[0072] In some other specific solutions, a collar 821 is formed on the first battery cell 82. The collar 821 is formed by bending the end of the first battery cell 82. The collar 821 is inserted into the distribution pole and contacts the distribution pole, so that the contact between the first battery cell 82 and the distribution pole is more stable. Preferably, a notch is formed on the collar 821, and the notch is used to avoid the second battery cell 92, the third battery cell, and the fourth battery cell. Example

[0073] The difference from Example 3 is that: Refer to the attached Fig.15, the stretching member 7 includes a stretching power structure 71 and a third driving roller 73. The stretching power structure 71 is used to drive the second guide roller 65 to move away from the first guide roller 64. Or the stretching power structure 71 is used to drive the third guide roller to move, the composite wire part is in contact with the third guide roller, and the movement of the third guide roller can stretch the composite wire. The stretching power structure 71 in this embodiment adopts one of a cylinder, a hydraulic cylinder and an electric push rod, mainly using the second guide roller 65 away from the first guide roller 64 to stretch the composite wire, or using the movement of the third guide roller to stretch the composite wire, and the third guide roller changes the composite wire originally transported in a straight line into a curved folded line for transport, thereby achieving the stretching of the composite wire. Then, when the tensile force on the composite wire is small, the tensile force on the composite wire is increased by the above method, and then the composite wire is wound on the winding roller 1, so that the elasticity of the composite wire application can be retained for a long time after the composite wire is wound on the winding roller 1.

[0074] See attached Figure 7 In some other embodiments, the second transmission member 4 is a lightweight aluminum shell; the lightweight aluminum shell forms the slot; the winding roller 1 is fixed to the second transmission member 4. Since the first friction portion 31 and the second friction portion 41 will slip, and multiple first friction portions 31 and second friction portions 41 are provided, when the first friction portion 31 and the second friction portion 41 slip against each other and pass over each other, there will be some positions where the first friction portion 31 cannot contact the second friction portion 41. Therefore, if the second transmission member 4 is heavy, there will be a large rotational inertia, which may cause the rotational inertia of the second transmission member 4 and the winding roller 1 to cause the composite wire to be subjected to a tension greater than the preset tensile force. The use of a lightweight aluminum shell can reduce the weight, thereby reducing the inertia, and avoiding the situation where the rotational inertia causes the composite wire to be subjected to a tension greater than the preset tensile force.

[0075] In a more specific solution, the winding device also includes a wire-pulling structure 12, which is used to drive the carrier frame 63 to move along the axial direction of the winding roller 1, so as to allow the composite wire to be wound at different positions of the winding roller 1, so that the composite wire is evenly wound on the winding roller 1, and avoid the situation where the composite wire is only wound at one place, resulting in a relatively narrow composite wire after winding. The wire-pulling structure 12 adopts a combination of a cylinder, a hydraulic cylinder or an electric push rod and a guide rail. Preferably, a lead screw nut pair is used.

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
