Description

Technical Field

[0001] This utility model belongs to the field of warp knitting machine technology, specifically relating to a combined lace patterned headband. Background Technology

[0002] Warp knitting machines, as key equipment in the textile industry, are widely used in the production of complex fabrics such as lace, frills, and mesh. The pattern head (or "pattern disc") is one of the core components of the warp knitting machine. Its function is to control the amount and tension of the warp yarns according to the preset pattern, thereby forming a specific pattern effect on the fabric.

[0003] In actual production, to adapt to the market demand for diverse varieties and small batches, it is often necessary to change the patterned warp heads. Traditional warp head heads mostly adopt an integral structure or a simple bolt fixing method. Once the integral warp head is manufactured, its pattern cannot be changed, resulting in extremely poor flexibility. While the bolt-fixed modular warp head can theoretically replace the warp head, it has significant drawbacks in actual operation: replacing the warp head requires tightening or loosening multiple bolts one by one, which is cumbersome, time-consuming, and labor-intensive, seriously affecting the production efficiency of the equipment. At the same time, after long-term use, the bolts are prone to problems such as stripping and corrosion, resulting in insufficient locking force. The warp head may loosen or shift during high-speed operation, thus affecting the accuracy of the pattern and even causing warp yarn breakage, resulting in defective products.

[0004] To address this, we propose a modular lace-patterned flower head that allows for quick installation and disassembly of the flower head, facilitating subsequent assembly and adjustments. Utility Model Content

[0005] The purpose of this invention is to provide a modular lace-patterned flower head that allows for quick installation and disassembly of the flower head, facilitating subsequent assembly.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A combined lace-patterned headband includes a hollow shaft and a flower disc. The hollow shaft has multiple sets of annularly distributed through grooves on its outer side, with four grooves in each set. Each flower disc has a mounting groove matching the diameter of the hollow shaft. Multiple locking holes are formed on the inner wall of each mounting groove. A rotating assembly is housed inside the hollow shaft, and multiple conical threaded sleeves are threaded onto the rotating assembly. Each conical threaded sleeve has four inclined T-shaped sliding grooves, each containing a T-shaped slider. Four sets of U-shaped frames are also provided on the inner wall of the hollow shaft, each with an elastic component. The bottom of each elastic component is fixedly connected to the T-shaped slider, and a locking rod is fixedly installed on the top of each elastic component, matching the through grooves and locking holes.

[0008] Furthermore, the rotating assembly includes a threaded rod disposed inside the hollow shaft, one end of which extends through the hollow shaft and is fitted with a rotating disk, and the threaded rod is threadedly connected to the conical threaded sleeve.

[0009] Furthermore, one end of the hollow shaft is provided with a plurality of first threaded holes in a circular array, and the rotating disk is provided with second threaded holes. Fixing bolts are provided inside the first threaded holes and the second threaded holes.

[0010] Furthermore, both the T-shaped slider and the T-shaped groove are provided with smooth surfaces.

[0011] Furthermore, the elastic component includes a movable hole formed on the U-shaped frame, a movable rod disposed inside the movable hole, the bottom of the movable rod being connected to the T-shaped slider, the top of the movable rod being connected to the locking rod, and a spring disposed on the movable rod, the spring being located between the U-shaped frame and the T-shaped slider.

[0012] Furthermore, a first limiting disc is fixedly installed on the hollow shaft, and a second limiting disc is threadedly installed.

[0013] Furthermore, a rubber layer is provided on the outer side of the locking rod.

[0014] The technical effects achieved by this utility model are as follows:

[0015] First, during the assembly of the flower trays, the different flower trays are sequentially installed onto the hollow shaft through their mounting slots, aligning with each set of through slots. Then, the rotating assembly is activated, driving multiple conical threaded sleeves to move. This causes the T-shaped slider to move within the T-shaped groove, moving the elastic component upwards on the U-shaped frame. The elastic component then drives the locking rod from inside the through slot into the locking hole, thus locking and securing the flower tray. For disassembly, simply reverse the rotation of the rotating assembly. This causes the multiple conical threaded sleeves to move in the opposite direction, and the T-shaped slider to move in the opposite direction within the T-shaped groove. This allows the elastic component to pull the locking rod out of the locking hole, and then the flower tray can be replaced to complete the assembly. This device allows for quick installation and disassembly of the flower trays, facilitating subsequent assembly. Attached Figure Description

Detailed Implementation

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-5 As shown, a combined lace-patterned head includes a hollow shaft 1 and a flower plate 2. Multiple sets of annularly distributed through grooves 3 are formed on the outer side of the hollow shaft 1, with four grooves in each set. Each flower plate 2 has an installation groove 4 matching the diameter of the hollow shaft 1. Multiple locking holes 5 are formed on the inner wall of the installation groove 4. A rotating assembly is installed inside the hollow shaft 1, and multiple conical threaded sleeves 6 are threaded onto the rotating assembly. Four inclined T-shaped sliding grooves 7 are formed on the conical threaded sleeves 6, and each T-shaped sliding groove 7 has a T-shaped slider 8 inside. Four sets of U-shaped frames 9 are set on the inner wall of the hollow shaft 1, and each U-shaped frame 9 has an elastic component. The bottom of the elastic component is fixedly connected to the T-shaped slider 8, and a locking rod 10 is fixedly installed on the top of the elastic component. The locking rod 10 matches the through grooves 3 and locking holes 5.

[0025] The rotating assembly includes a threaded rod 11 disposed inside the hollow shaft 1. One end of the threaded rod 11 extends through the hollow shaft 1 and is fitted with a rotating disk 12. The threaded rod 11 is threadedly connected to a conical threaded sleeve 6.

[0026] This configuration allows the rotating disk 12 to drive the threaded rod 11 to rotate, and the threaded rod 11 to drive the conical threaded sleeve 6 to move.

[0027] Meanwhile, a plurality of first threaded holes 13 are arranged in a ring array at one end of the hollow shaft 1, and a second threaded hole 14 is provided on the rotating disk 12. Fixing bolts 15 are provided inside the first threaded holes 13 and the second threaded holes 14. The threaded rod 11 can be limited and locked by the fixing bolts 15 to prevent slippage.

[0028] Both the T-shaped slider 8 and the T-shaped groove 7 are provided with smooth surfaces, which can reduce the friction during movement and make it easy to rotate.

[0029] The elastic component includes a movable hole formed in the U-shaped frame 9, inside which a movable rod 16 is disposed. The bottom of the movable rod 16 is connected to the T-shaped slider 8, and the top of the movable rod 16 is connected to the locking rod 10. A spring 17 is disposed on the movable rod 16, and the spring 17 is located between the U-shaped frame 9 and the T-shaped slider 8. This arrangement allows the movable rod 16 to move upward and compress the spring 17 when the T-shaped slider 8 slides, thereby causing the locking rod 10 to extend and operate.

[0030] The diameter of the locking rod 10 is larger than the diameter of the movable rod 16. This design allows the movable rod 16 to enter and provide support when the locking rod 10 enters the through groove 3, without causing interference.

[0031] A first limiting plate 18 and a threaded second limiting plate 19 are fixedly installed on the hollow shaft 1. This arrangement can limit and press the flower plate 2. When in use, the second limiting plate 19 can be removed to install the flower plate 2.

[0032] A rubber layer is provided on the outside of the locking rod 10. The rubber layer ensures that the locking rod 10 can enter the locking hole 5 without any gaps, thus improving the locking effect.

[0033] The working principle of this utility model is as follows: First, during the assembly of the flower discs 2, different flower discs 2 are sequentially installed on the hollow shaft 1 through their mounting grooves 4 and aligned with each set of through grooves 3. Then, the rotating component is activated, driving multiple conical threaded sleeves 6 to move, thereby causing the T-shaped slider 8 to move inside the T-shaped groove 7 and driving the elastic component to move upward on the U-shaped frame 9. The elastic component drives the locking rod 10 from inside the through groove 3 into the locking hole 5, thereby locking and fixing the flower disc 2. For disassembly, simply reverse the rotation of the rotating component. The rotating component drives the multiple conical threaded sleeves 6 to move in the opposite direction, and the T-shaped slider 8 to move in the opposite direction inside the T-shaped groove 7, thereby causing the elastic component to pull the locking rod 10 out of the locking hole 5. Then, the flower disc 2 can be replaced to complete the assembly. This device allows for quick installation and disassembly of the flower discs 2, facilitating subsequent assembly.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
