Description

Technical Field

[0001] This utility model relates to the field of textile accessories technology, and in particular to a mounting base for a yarn feeder. Background Technology

[0002] The yarn feeder is a core component in textile machinery (such as circular knitting machines and flat knitting machines) used to control the yarn path. It mainly guides the yarn into the needle hook to form the fabric structure. Its function and design directly affect weaving efficiency and finished product quality. The yarn feeder ensures that the yarn is stably transported along the preset path through a fixed or adjustable yarn guide channel, preventing problems such as unhooking and missed needles.

[0003] The intelligent yarn feeder achieves intelligent operation through independent control of servo motors and a precision transmission structure, significantly improving weaving efficiency and precision. Each yarn feeder is controlled by an independent servo motor, replacing the traditional method of the machine head driving the yarn feeder. Up to 16 yarn feeders can be controlled independently, and the encoder provides real-time feedback of position information to ensure that the yarn feeders are accurately stopped at the preset point. Relying on the I-shaped linear guide rail and synchronous belt transmission mechanism, the yarn feeder component can move flexibly back and forth along the guide rail. Combined with the closed-loop control system, the stroke is monitored in real time to reduce the risk of mechanical deviation.

[0004] Typically, a smart yarn feeder has four guide rails, each with four synchronous belts arranged vertically. Each synchronous belt connects to one yarn feeder, resulting in four yarn feeders per guide rail. Two yarn feeders are located on each side of the guide rail. Each yarn feeder's synchronous belt is equipped with its own servo motor, requiring a total of 16 motors. Each guide rail corresponds to four motors, and the four motors on the same guide rail are arranged in a stepped manner, with the motor height decreasing as they approach the guide rail. Motors at the same height on different guide rails are in the same row, resulting in a total of four rows. However, in the smart yarn feeder, all 16 motors are concentrated at the same end of the guide rail, which is uncoordinated and protrudes significantly, making it susceptible to collisions from people and objects, potentially causing damage to the motors. Furthermore, the stress on the smart yarn feeder is uneven, making disassembly and assembly more difficult, and the stability after installation is not high. To increase stability, fasteners and supports are needed, thus increasing the overall size of the device and the space it occupies. Utility Model Content

[0005] The purpose of this invention is to provide a mounting base for a yarn feeder to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A mounting base for a yarn feeder includes multiple profiles arranged side-by-side. Each profile has two rows of rotationally symmetrical synchronous wheels rotatably connected between its two bottom surfaces. The two rows of synchronous wheels are respectively close to the upper and lower bottom surfaces of the profile. Base plates are fixedly connected to both ends of the bottom surfaces of each profile. Step plates are fixedly connected to the base plates at both ends of each profile, and the step plates at both ends of the profile are rotationally symmetrical. The upper bottom surface of the step plate at one end of the profile is fixedly connected to the adjacent base plate, and the lower bottom surface of the step plate at the other end is fixedly connected to the adjacent base plate. The plates are fixedly connected. Each step of the stepped plate of the profile is fixedly connected to multiple motors through a connecting plate. The output shaft of each motor is fixedly connected to a synchronous pulley two. The output shafts of the motors at both ends of the profile face upward and downward respectively. The synchronous pulley two on the motor with the output shaft facing downward is connected to the synchronous pulley one on the bottom surface of the profile in the same column. The synchronous pulley two on the motor with the output shaft facing upward is connected to the synchronous pulley one on the bottom surface of the profile in the same column. The synchronous belt passes through the side of the profile.

[0008] Using the above technical solution, motors on the same height step on the stepped plate correspond to different profiles. Motors corresponding to the same profile are located in the same column. A synchronous belt connects the synchronous pulley 2 of the motor in the same column with its output shaft facing upwards to the synchronous pulley 2 in a column on the profile near its upper bottom surface. The closer the synchronous pulley 2 is to the top, the farther the connected motor is from the profile. Similarly, a synchronous belt connects the synchronous pulley 2 of the motor in the same column with its output shaft facing downwards to the synchronous pulley 2 in a column on the profile near its lower bottom surface. The closer the synchronous pulley 2 is to the bottom, the farther the connected motor is from the profile. By installing stepped plates facing different directions at both ends of the profile and dividing the synchronous pulleys on the profile into two rows, one near the top of one end and the other near the bottom of the other, the motor can be fixedly connected to both ends of the profile, and the synchronous pulleys on the profile can be connected to the motor. This eliminates the need to concentrate all the motors at one end of the profile, resulting in a more coordinated design, less susceptibility to external impacts, more even force distribution, and easier disassembly and installation. Furthermore, it provides greater stability when installed on textile equipment, eliminating the need for additional fasteners and supports for reinforcement, thus saving space on the equipment.

[0009] Preferably, each of the synchronous pulleys is provided with two symmetrical horizontal slots at the position of the profile. The synchronous pulley is located at the junction of the two symmetrical slots. The synchronous belt between the connected synchronous pulleys passes through the junction of the two symmetrical slots.

[0010] By adopting the above technical solution, the synchronous belt can be embedded in the groove, reducing the external influences it is subjected to.

[0011] Preferably, each profile has two mounting blocks slidably connected to both sides, each mounting block is fixedly connected to a corresponding timing belt, and each mounting block is connected to a yarn nozzle.

[0012] Using the above technical solution, the motor drives the synchronous belt to rotate through synchronous pulley one and synchronous pulley two. The synchronous belt pulls the mounting block to move, and the mounting block then drives the yarn nozzle to move.

[0013] Preferably, the outer walls of the two slots near the upper and lower bottom surfaces of each side of the profile are respectively embedded with guide shafts, and each mounting block is rotatably connected to two guide wheels with grooves on both sides. The guide wheels on both sides of the mounting block are respectively engaged with two guide shafts on the same side, and the guide wheels are slidably connected to the guide posts.

[0014] Using the above technical solution, the synchronous belt pulls the mounting block to move along the guide shaft, while the guide wheel of the mounting block rotates, reducing the friction between the mounting block and the profile and increasing the stability of the synchronous belt movement.

[0015] Preferably, a U-shaped cover plate is also included. A cover plate one and a cover plate two are provided at one end of the profile where the motor with the output shaft facing upward is fixedly connected. The opening of cover plate one faces upward and is embedded in a section of the profile. The side wall of cover plate one is fixedly connected to the bottom plate. A small part of the synchronous belt, a part of the stepped plate, and each row of synchronous pulleys one near the bottom surface of the profile are located inside cover plate one. The opening of cover plate two faces downward and is fixedly connected to the stepped plate. Cover plate two is embedded in a part of the synchronous belt, the other part of the stepped plate, the motor output shaft, and the synchronous pulleys two on the output shaft. A cover plate three is provided at one end of the profile where the motor with the output shaft facing upward is fixedly connected. The opening of cover plate three faces upward and is embedded in the output shaft of the motor at the other end of the profile, the synchronous pulleys two on it, the stepped plate, a part of the synchronous belt, a part of the profile, and each row of synchronous pulleys one near the top surface of the profile. Cover plate three is fixedly connected to the bottom plate.

[0016] The above technical solution protects the motor output shaft and synchronous pulley, reducing external damage, and also limits the synchronous belt to prevent it from vibrating.

[0017] Preferably, each connecting plate is connected to multiple small plates by bolts. The bolts pass through the connecting plate and are threaded to the small plates. The motor is fixedly connected to the small plates. The connecting plate has a waist-shaped groove at the connection with the bolts. Each small plate is integrally formed with a slider. The connecting plate has a groove corresponding to the slider. The slider is embedded in the groove and is slidably connected to the connecting plate.

[0018] By adopting the above technical solution, the force exerted on the connecting plate by the tail of the bolt is reduced by loosening the bolt. Then, the small plate can be moved along the waist groove and the slide groove. The small plate drives the motor and the synchronous pulley 1 on the motor output shaft to move, so that the synchronous pulley 1 moves closer to and further away from the synchronous pulley 2 connected to it, thereby changing the distance between the connected synchronous pulley 1 and synchronous pulley 2, and thus adjusting the tension of the synchronous belt.

[0030] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0031] SeeFigure 1 , Figure 5 and Figure 7 A mounting base for a yarn feeder includes multiple profiles 1 arranged side by side, and one to four profiles 1 can be set. The portion between the two bottom surfaces of each profile 1 is rotatably connected to two rows of synchronous wheels 2 in a rotationally symmetrical manner. There are two wheels in each row, and one profile 1 has four synchronous wheels 2. The two rows of synchronous wheels 2 are close to the upper and lower bottom surfaces of the profile 1, respectively. Each position of the profile 1 where the synchronous wheel 2 is located has two horizontal slots 8 that are symmetrically arranged front and back. A notch is opened at the junction of the two symmetrical slots 8. The synchronous wheel 2 is located in the notch at the junction of the two symmetrical slots 8 where it is located.

[0032] See Figure 1 , Figure 3 , Figure 4 , Figure 8 and Figure 9 A base plate 3 is fixedly connected to both ends of the bottom surface of the profile 1. The base plate 3 connects multiple profiles 1 together. The base plate 3 is fixedly connected to the profile 1 by bolts. The base plate 3 has multiple through holes, and the profile 1 has multiple corresponding threaded holes. Each threaded hole of the base plate 3 is fitted with a bolt, which then passes into the threaded hole of the profile 1, and the bolt is threadedly connected to the profile 1. A step plate 4 is fixedly connected to the lower part of the base plate 3 at both ends of each profile 1 by bolts. Multiple step plates 4 can be set. Each step plate 4 is located in front of two adjacent step plates 4, and the step plates 4 at both ends of the profile 1 are rotationally symmetrical. The upper bottom surface of the step plate 4 at one end of the profile 1, i.e., the highest step surface on the step plate 4, is fixedly connected to the base plate 3 next to it. The lowest step surface of the step plate 4 is away from the end of the profile 1. The lower bottom surface of the step plate 4 at the other end, opposite to its step surface, is fixedly connected to the base plate 3 next to it.

[0033] See Figure 2 , Figure 3 , Figure 8 and Figure 9Each step of the stepped plate 4 of profile 1 is fixedly connected to a connecting plate 15 by bolts. Each connecting plate 15 is connected to multiple small plates 16 by bolts. The bolts pass through the connecting plate 15 and are threadedly connected to the small plates 16. Each small plate 16 is fixedly connected to a motor 5. The small plate 16 and the housing of the motor 5 are integrally formed together. The output shaft of the motor 5 passes through the small plate 16 and the connecting plate 15, and the output shaft of each motor 5 is located at a different height. The connecting plate 15 has a waist-shaped groove 17 at the connection with the bolt. Each small plate 16 is integrally formed with a slider 19. The connecting plate 15 has a groove 18 corresponding to the slider 19. The slider 19 is embedded in the groove 18 and is slidably connected to the connecting plate 15. By loosening the bolts, the force exerted on the connecting plate 15 by its tail is reduced. Then, the small plate 16 can be moved along the waist-shaped groove 17 and the sliding groove 18. The small plate 16 drives the motor 5 and the synchronous pulley 2 on the output shaft of the motor 5 to move, so that the synchronous pulley 2 moves closer to and further away from the synchronous pulley 6 connected to it, changing the distance between the connected synchronous pulley 2 and synchronous pulley 6, thereby adjusting the tension of the synchronous belt 7. The output shaft of each motor 5 is fixedly connected to the synchronous pulley 2 6, and the output shafts of the motors 5 at both ends of the profile 1 face upward and downward respectively. The synchronous pulley 2 6 on the motor 5 with the output shaft facing downward is connected to the synchronous pulley 2 near the bottom surface of the profile 1 in the same row, and the synchronous pulley 2 6 on the motor 5 with the output shaft facing upward is connected to the synchronous pulley 2 near the bottom surface of the profile 1 in the same row, and the synchronous belt 7 passes through the notch where the synchronous pulley 2 is connected.

[0034] Figure 1 , Figure 3 , Figure 5 and Figure 10 Each profile 1 has two mounting blocks 9 slidably connected to both sides. Each mounting block 9 is fixedly connected to its corresponding synchronous belt 7 via a pair of clamping plates. The two clamping plates in each pair are located on the inner and outer sides of the synchronous belt 7, clamping the synchronous belt 7. The two clamping plates in each pair are fixed together with bolts, and the mounting block 9 is then fixedly connected to the clamping plates with bolts. Guide shafts 10 are embedded in the outer walls of two slots 8 near the upper and lower bottom surfaces on each side of the profile 1. Guide wheels 11 with grooves are rotatably connected to both sides of each mounting block 9. The guide wheels 11 on both sides of the mounting block 9 are respectively engaged with the two guide shafts 10 on the same side. The guide wheels 11 are slidably connected to the guide posts. Each mounting block 9 is connected to a yarn nozzle.

[0035] See Figure 1 and Figure 2It also includes a U-shaped cover plate. A cover plate 12 and a cover plate 23 are provided at one end of the profile 1 where the motor 5 with the output shaft facing upward is fixedly connected. The opening of the cover plate 12 faces upward and is embedded in a section of the profile 1. The side wall of the cover plate 12 is fixedly connected to the bottom plate 3. A small part of the synchronous belt 7, a part of the stepped plate 4, and each row of synchronous pulleys 12 near the bottom surface of the profile 1 are located inside the cover plate 12. The opening of the cover plate 23 faces downward and is fixedly connected to the stepped plate 4. The cover plate 23 is embedded in a part of the synchronous belt 7, the other part of the stepped plate 4, the output shaft of the motor 5, and the synchronous pulleys 26 on the output shaft. A cover plate 3 14 is provided at one end of the profile 1 to which the motor 5 with its output shaft facing upwards is fixedly connected. The cover plate 3 14 has an upward opening and is embedded in the other end of the profile 1, covering the output shaft of the motor 5, the synchronous pulley 6, the stepped plate 4, a part of the synchronous belt 7, a part of the profile 1, and each row of synchronous pulleys 2 near the bottom surface of the profile 1. The cover plate 3 14 is fixedly connected to the base plate 3. The cover plate is used to protect the output shaft of the motor 5 and the synchronous pulleys, reducing external damage, and at the same time to restrict the synchronous belt 7 to prevent it from vibrating.

[0036] Working principle: Motors 5 on the same height step of the stair plate 4 correspond to different profiles 1. Motors 5 corresponding to the same profile 1 are located in the same column. A synchronous belt 7 connects the synchronous pulley 6 of the motor 5 in the same column with its output shaft facing upwards to the synchronous pulley 6 in the same column near the top surface of the profile 1. The closer the synchronous pulley 6 is to the top, the farther the connected motor 5 is from the profile 1. Similarly, a synchronous belt 7 connects the synchronous pulley 6 of the motor 5 in the same column with its output shaft facing downwards to the synchronous pulley 6 in the same column near the bottom surface of the profile 1. The closer the synchronous pulley 6 is to the bottom, the farther the connected motor 5 is from the profile 1. By installing stepped plates 4 facing different directions at both ends of the profile 1, and dividing the synchronous pulleys on the profile 1 into two rows, one near the top of one end of the profile 1 and the other near the bottom of the other end, the motors 5 can be fixedly connected to both ends of the profile 1 respectively, and the synchronous pulleys on the profile 1 can all be connected to the motors 5. This eliminates the need to concentrate all the motors 5 at one end of the profile 1, making it more coordinated, less susceptible to external collisions, and with more even force distribution. It is also easier to disassemble and install, and it is more stable after being installed on textile equipment. It does not require the addition of fasteners and supports for reinforcement, thus increasing the space occupied by the equipment.
