Description

Technical Field

[0001] The utility model relates to the technical field of weft storage devices, in particular to a yarn storage drum for a weft storage device. Background Art

[0002] The weft storage device is a temporary storage device for the weft yarn unwound from the bobbin before it is introduced into the shed. It is usually composed of a motor, a yarn storage drum, a yarn winding disk, a damping ring, a tensioner, a yarn arrangement structure, etc. Its main functions include reducing the unwinding speed of the bobbin, reducing loop unwinding and end breakage, reducing the resistance of the unwinding weft yarn during weft insertion, and improving the quality of the fabric. The yarn storage drum is an important component of the weft storage device. In the prior art, the swinging parts or connecting parts of the yarn storage drum are generally detachably connected to the main body. Since the yarn storage drum will vibrate during operation, it is easy to cause the yarn storage drum to deform and displace, resulting in poor tension effect, increasing costs, and affecting processing efficiency. Utility Model Content

[0003] The utility model provides a yarn storage drum for a weft storage device, which solves the problems of poor stability and high cost caused by loose swinging parts in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] Yarn storage drum for weft feeder, including

[0006] main body;

[0007] A swinging member, arranged on the side of the main body;

[0008] The invention is characterized in that the swinging part and the main body are integrally formed, which can improve the structural strength and stability of the entire yarn storage drum, reduce failures caused by loose or worn connecting parts, simplify the manufacturing process, and reduce the manufacturing cost.

[0009] Furthermore, the swinging members are evenly distributed circumferentially on the main body to evenly control the tension of the yarn, which helps to ensure that the yarn maintains a stable tension throughout the entire supply process, thereby improving weaving quality and efficiency, while reducing failures caused by vibration or impact and improving the reliability and durability of the equipment.

[0010] Furthermore, the swinging part includes a limit plate, a mounting groove is provided on the surface of the limit plate, and a wear-resistant strip is installed in the through groove. Since the yarn will generate friction with the limit plate during the supply process, the wear-resistant strip can effectively reduce the wear of the limit plate caused by such friction, thereby extending the service life of the limit plate. By replacing the wear-resistant strips of different materials or specifications, it can adapt to different yarn types and weaving requirements, thereby improving the applicability of the equipment.

[0011] Furthermore, the opening ends of the installation grooves are all set to arc surfaces, which reduces stress concentration during installation and removal, reduces the risk of breakage and damage of the wear-resistant inserts in the installation grooves, increases the service life, and facilitates the clip-on installation of the wear-resistant inserts.

[0012] Furthermore, a mounting hole is provided in the mounting groove, and the screw cooperates with the mounting hole to realize the connection between the wear-resistant insert and the swing part. The screw connection is firm and easy to disassemble and assemble. When the insert needs to be replaced or repaired, it can be easily removed by loosening the screw, and then the new insert is fixed in the mounting groove by the screw.

[0013] Furthermore, the swing member also includes a swing block, on which a rib is provided, and the rib is connected to the limit plate. The rib can optimize the stress distribution on the swing member, prevent fracture or deformation caused by stress concentration, and at the same time enhance the structural stability of the entire swing member.

[0014] Furthermore, a positioning groove is provided at one end of the main body, and the positioning groove is used to install the end cover, which is convenient for positioning and installing the end cover and can effectively prevent the end cover from loosening or falling off during use, thereby ensuring the overall structural stability of the yarn storage drum.

[0015] Furthermore, a limiting portion is provided on the swing block, which is used to limit the end cover. The limiting portion can ensure that the end cover remains in a fixed position after installation to prevent it from being displaced or loosened during use, which is crucial to maintaining the stability and normal working state of the yarn storage drum.

[0016] Furthermore, the swing block is connected to the main body through a connecting plate, and a limiting cavity is formed between the connecting plate, the main body and the swing block. The limiting cavity is used to limit the end cover. When the end cover is installed, the end cover slides down along the surface of the limiting portion, and the middle position of the end cover is clamped in the positioning groove, and the edge position is clamped in the limiting cavity, thereby realizing double clamping and locking, thereby improving the connection strength and stability. The limiting cavity can ensure that the end cover is not easy to fall off or shift when subjected to external force, thereby improving the safety of the yarn storage drum.

[0017] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0018] The utility model discloses a yarn storage drum for a weft storage device, wherein the swinging part and the main body are integrally formed, which can improve the structural strength and stability of the entire yarn storage drum, reduce failures caused by looseness and wear of the connecting part or the swinging part, simplify the manufacturing process, and reduce the manufacturing cost.
