Description

Technical Field

[0001] This utility model relates to the field of textiles, and more specifically, to a device for yarn selection in weaving. Background Technology

[0002] The patent with publication number CN1089916A discloses a weft selection and weft feeding device for a loom. It discloses that the yarn is longitudinally guided by a yarn guide driven by an eccentric transmission device and a drive motor. Each yarn guide has an independent drive motor to ensure that a single yarn guide can move independently of other loom components.

[0003] Meanwhile, in the prior art, in order to increase the number and density of yarn guides, two parallel mounting planes are set up, and the drive motors are distributed on the opposite sides of the two mounting planes. The arrangement density of the yarn guides is increased by two sets of drive motors arranged in an alternating manner. However, both the motors and the mounting planes have a certain thickness. The double-layer structure increases the thickness of the yarn selection device, which leads to a smaller range of deflection angles that can be selected during installation, and increases the probability of yarn breakage. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for yarn selection in weaving.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a device for yarn selection in weaving, comprising a base and a plurality of drive motors fixedly connected to the top of the base, a swing arm being drivenly connected to the output end of the drive motor, a rod being rotatably connected to the end of the swing arm away from the output end of the drive motor, a limiting member being fixedly connected to the base, the limiting member being slidably connected to the rod, the plurality of drive motors being concentrated on the back side of the base, the plurality of drive motors including a plurality of first motors and a plurality of second motors, the first motors and second motors being alternately spaced, the distance from the first motor to the bottom end of the base being greater than the distance from the second motor to the bottom end of the base.

[0006] The present invention is further configured such that the length of the rod corresponding to the first motor is greater than the length of the rod corresponding to the second motor.

[0007] The present invention is further configured such that: an arc-shaped groove for accommodating the movement of the swing arm is provided on the front side of the base, and the swing arm slides in the arc-shaped groove.

[0008] The present invention is further configured such that the arc of the arc groove is less than or equal to 180°, and any one of the arc grooves is located on the same side of the corresponding drive motor.

[0009] The present invention is further configured such that: the rod is a round rod, the limiting member is composed of several sliding sleeves, and any one of the round rods passes through only one sliding sleeve.

[0010] The present invention is further configured such that: the rod is composed of a transmission rod and a sliding rod, one end of the transmission rod is rotatably connected to the swing arm, the other end of the transmission rod is rotatably connected to the sliding rod, and the sliding rod is slidably connected to the limiting member.

[0011] The present invention is further configured such that: the limiting member is composed of a plurality of first limiting sleeves and a plurality of second limiting sleeves, and any sliding rod passes through a first limiting sleeve and a second limiting sleeve.

[0012] The present invention is further configured such that the base is integrally formed.

[0013] In summary, this utility model has the following beneficial effects: it reduces the overall thickness of the yarn selection device, allows the base to deflect over a larger range in the same installation space, facilitates the selection of the optimal installation angle, and reduces the yarn breakage rate. The staggered arrangement of the first and second motors increases the density of the rods while ensuring that adjacent drive motors do not interfere with each other. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example 1: A device for yarn selection in weaving, such as Figure 1 , Figure 2 , Figure 3As shown, the device includes a base 1 and several drive motors 2 fixedly connected to the top of the base 1. A swing arm 3 is drivenly connected to the output end of the drive motor 2. A rod is rotatably connected to the end of the swing arm 3 away from the output end of the drive motor 2. A limiting member is fixedly connected to the base 1. The limiting member is slidably connected to the rod. The several drive motors 2 are concentrated on the back of the base 1. The several drive motors 2 include several first motors 4 and several second motors 5. The first motors 4 and second motors 5 are alternately arranged. The distance from the first motor 4 to the bottom of the base 1 is greater than the distance from the second motor 5 to the bottom of the base 1. The length of the rod corresponding to the first motor 4 is greater than the length of the rod corresponding to the second motor 5. The base 1 is integrally formed.

[0021] Specifically, the front of the base 1 is covered with a cover plate, and the back of the base 1 has a cover to protect the drive motor 2. The drive motor 2 drives the swing arm 3 to swing, thereby causing the rod to slide relative to the limiting member. The bottom end of the rod is fixedly connected to a magnetic ring for the yarn to pass through. The yarn selection is completed by the up and down movement of the magnetic ring. The first motor 4 and the second motor 5 are both located on the same side of the base 1, which reduces the overall thickness of the yarn selection device. In the same installation space, the base 1 can deflect a larger range, which is convenient for selecting the optimal installation angle and reducing the yarn breakage rate. The staggered arrangement of the first motor 4 and the second motor 5 increases the density of the rods while ensuring that adjacent drive motors 2 do not interfere with each other. Different rod lengths are used to adapt to the different installation positions of the first motor 4 and the second motor 5, so that when all the swing arms 3 are located at the same quadrant point of the corresponding drive motor 2, all the magnetic rings can be in a straight line. At the same time, since the base 1 only needs to install the drive motor 2 on one side, the one-piece base 1 is easier to produce and has higher structural stability than the structure that requires at least two base 1 pieces to be assembled together.

[0022] like Figure 2 , Figure 3 As shown, the front of the base 1 is provided with an arc-shaped groove 6 for accommodating the movement of the swing arm 3. The swing arm 3 slides in the arc-shaped groove 6. The arc of the arc-shaped groove 6 is less than or equal to 180°. Any arc-shaped groove 6 is located on the same side of the corresponding drive motor 2. Specifically, the arc-shaped groove 6 makes the swing arm 3 embedded in the front of the base 1, reducing the gap between the rod and the base 1, and further reducing the thickness of the yarn selection device. In this embodiment, from the front view of the base 1, all arc-shaped grooves 6 are located on the right side of the corresponding drive motor 2, ensuring the spacing between adjacent swing arms 3 and avoiding interference between swing arms 3.

[0023] like Figure 2 , Figure 3As shown, the rod is a round rod 7, and the limiting component is composed of several sliding sleeves 8. Each round rod 7 passes through only one sliding sleeve 8. Specifically, the rod is a one-piece round rod 7, which ensures the structural stability of the rod. One round rod 7 corresponds to one sliding sleeve 8. The reciprocating motion of the rod is ensured by the elastic deformation of the rod. The single sliding sleeve 8 ensures that the magnetic ring makes linear motion while reducing the friction force on the rod, that is, reducing the kinetic energy loss.

[0024] Example 2: A device for yarn selection in weaving, such as... Figure 4 As shown, the difference from Embodiment 1 is that the rod is composed of a transmission rod 9 and a sliding rod 10. One end of the transmission rod 9 is rotatably connected to the swing arm 3, and the other end of the transmission rod 9 is rotatably connected to the sliding rod 10. The sliding rod 10 is slidably connected to the limiting member. The limiting member is composed of several first limiting sleeves 11 and several second limiting sleeves 12. Any sliding rod 10 passes through a first limiting sleeve 11 and a second limiting sleeve 12.

[0025] Specifically, the transmission rod 9 and the sliding rod 10 are rotatably connected by a rotating shaft. The sliding rod 10 passes through the first limiting sleeve 11 and the second limiting sleeve 12 at the same time, which ensures the stability of the movement path of the sliding rod 10. Furthermore, the sliding rod 10 is connected to the swing arm 3 through the transmission rod 9, which avoids the elastic deformation of the sliding rod 10, reduces the vibration of the sliding rod 10, and ensures the movement stability of the sliding rod 10 and the magnetic ring.

All technical solutions falling within the scope of this utility model's concept are protected. It should 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.
