Description

Technical Field

[0001] The utility model relates to the technical field of combined creels, in particular to a combined creel for a seamless underwear machine which meets the requirements of multiple specifications. Background Art

[0002] In the textile industry, seamless underwear machines are key equipment for producing seamless underwear, and the yarn frame, as an important component of seamless underwear machines, has a direct impact on the quality and efficiency of underwear production. As consumers' demand for personalized and diversified seamless underwear continues to grow, the market's requirements for the styles, materials, and specifications of seamless underwear are increasing. However, most existing seamless underwear machine yarn frames are fixed structures that can only accommodate a single or a few yarn specifications and cannot meet the needs of producing multiple yarn specifications simultaneously. When seamless underwear of different specifications needs to be produced, it is often necessary to stop the machine and replace the yarn frame, which not only increases operating time and labor intensity, but also seriously reduces production efficiency and increases production costs.

[0003] Chinese patent CN221810442U discloses a seamless underwear machine yarn rack, including a main body bracket, a plurality of groups of splicing components are provided on the top of the main body bracket, and the splicing components are used to assemble and increase the number of yarn racks, and a plurality of groups of quick-install components are provided on the front and back of the splicing components, and the quick-install components are used to quickly install yarn. This patent installs a splicing component, and uses a combination sleeve to provide a limit for the internal combination column. The positioning plate can provide an installation position for the internal structure. The adjusting screw can drive the bottom adjustment plate to rise by rotating, and the positioning shaft can provide the flip adjustment capability for the flip buckle. After the flip buckle is combined with the fixed buckle, the adjustment plate can be controlled to rise to limit the movement. Multiple groups of yarn racks can be combined through the splicing component, thereby improving the flexibility of the device and facilitating the adjustment of the device specifications according to different needs.

[0004] This existing technology utilizes splicable brackets to form a single unit and secure the brackets with a splicing assembly. However, this technology still has significant limitations. The retaining frames on the yarn bobbins are welded directly to the brackets. This fixed connection prevents the flexible adjustment of the number of bobbins based on actual production needs. When producing seamless underwear of varying specifications and yarn usage, the bobbin configuration cannot be quickly adjusted, limiting the ability to accommodate multiple yarn specifications.

DETAILED DESCRIPTION

[0022] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figures 1-6 As shown, the utility model provides a combined yarn frame for a seamless underwear machine that meets the needs of multiple specifications, including: a base 1; a support frame 2, which is provided with several pieces, and two adjacent support frames 2 can be spliced, and one of the support frames 2 can be spliced ​​with the base 1; a limiting assembly 3, which is provided with several pieces and is arranged on the base 1 and the support frame 2 to fix the base 1 and the support frame 2, or to fix two adjacent support frames 2; a wheel frame assembly 4, which is provided on the support frame 2 and can slide on the support frame 2; a slide groove 24 is provided on the front and back sides of the support frame 2, the wheel frame assembly 4 includes a support frame 41 and a slider 411 installed on the back of the support frame 41, the slider 411 and the slide groove 24 can be slidably matched, and the wheel frame assembly 4 also includes a fixing structure that can fix the wheel frame assembly 4 on the support frame 2.

[0024] During actual use, first determine the required number of support frames 2 based on the specific specifications of underwear production. Place the base 1 in a suitable position, then splice and fix one support frame 2 to the base 1 through the limiting component 3, and then splice other support frames 2 in sequence as needed, using the limiting component 3 to ensure that adjacent support frames 2 are firmly spliced ​​together to form a yarn frame main structure that meets the size requirements. Afterwards, install the wheel frame assembly 4 on the support frame 2, so that the slider 411 on the back of the support frame 41 cooperates with the slide groove 24 on the support frame 2 to achieve the sliding installation of the wheel frame assembly 4 on the support frame 2. According to the layout requirements of the yarn during the production process, slide the wheel frame assembly 4 to the appropriate position, and then use the fixing structure on the wheel frame assembly 4 to fix it to the support frame 2. Finally, place the yarn bobbin on the support frame 41 of the wheel frame assembly 4, and the yarn is drawn out from the yarn bobbin to provide the yarn required for production for the seamless underwear machine. When production requirements change and the creel structure or yarn position needs to be adjusted, the fixing of the limit component 3 on the support frame 2 can be loosened, and the support frame 2 can be re-spliced ​​to change the creel size; or the fixing structure on the wheel frame component 4 can be loosened, the wheel frame component 4 can be slid to a new position and re-fixed, thereby meeting the production needs of underwear of different specifications.

[0025] The fixing structure includes two upper and lower screw rods 412 that can rotate on the support frame 41 , and a clamping block 413 that can abut against the support frame 2 is further provided at the bottom of the screw rod 412 .

[0026] When the wheel frame assembly 4 needs to be fixed to a specific position of the support frame 2, the operator rotates the upper and lower screws 412 on the support frame 41. Due to the threaded fit between the screw 412 and the support frame 41, as the screw 412 rotates, the screw 412 will move downward in the vertical direction. During the downward movement of the screw 412, the clamping block 413 at its bottom will be driven to move downward together until the clamping block 413 is in close contact with the surface of the support frame 2. At this time, the clamping block 413 applies a certain pressure to the support frame 2, and the friction between the clamping block 413 and the support frame 2 firmly fixes the wheel frame assembly 4 on the support frame 2, preventing the wheel frame assembly 4 from being displaced due to vibration and other reasons during the production process, ensuring that the yarn can be stably drawn out from the yarn bobbin, and providing a reliable yarn supply for the seamless underwear machine.

[0027] The wheel frame assembly 4 also includes a movable frame 42 that can slide with the support frame 41. A spring that can reset the movable frame 42 is also provided inside the support frame 41. One end of the spring is connected to the movable frame 42, and the other end is connected to the inner wall of the support frame 41. A clamping disk 48 is rotatably provided in both the support frame 41 and the movable frame 42. The wheel frame assembly 4 also includes a yarn wheel 43 clamped in the clamping disk 48. The yarn wheel 43 has a plurality of limit slots along its length, and a plurality of limit blocks that cooperate with the limit slots are provided in the center of the clamping disk 48.

[0028] When the yarn wheel 43 needs to be installed, the yarn wheel 43 is placed between the support frame 41 and the clamping disk 48 of the movable frame 42. Since the movable frame 42 can slide, during the installation process, the movable frame 42 can be moved away from the support frame 41 to increase the distance between the two clamping disks 48, making it easier to insert the yarn wheel 43. After inserting the yarn wheel 43, the movable frame 42 is released. Under the action of the spring inside the support frame 41, the movable frame 42 will slide toward the support frame 41, so that the two clamping disks 48 clamp the yarn wheel 43 in the middle. At the same time, the limit block at the center of the clamping disk 48 will be inserted into the limit groove at the center of the yarn wheel 43, ensuring that the yarn wheel 43 and the clamping disk 48 rotate synchronously.

[0029] The wheel frame assembly 4 also includes a connecting column 44 arranged on the support frame 41, and a detachable plug-in column 45 is provided on the connecting column 44. A yarn guide ring 46 for guiding the yarn is fixedly installed at one end of the plug-in column 45 away from the connecting column 44, and a wire wheel 47 is also rotatably provided on the plug-in column 45 near the front of the yarn guide ring 46.

[0030] The base 1 is provided with a first slot 11, the bottom of the support frame 2 is provided with a post 21, and the top of the support frame 2 is provided with a second slot 23. The post 21 of one support frame 2 can be inserted into the first slot 11, and the post 21 of one support frame 2 can also be inserted into another second slot 23. The base 1 and the support frame 2 are locked by a limit assembly 3, and two adjacent support frames 2 are also locked using the limit assembly 3. The limit assembly 3 includes a shell 31 that can be fixed to the outside of the base 1 or the support frame 2. A plug-in 32 is slidably provided inside the shell 31. Slots 22 for inserting the plug-in 32 are also provided on both sides of the post 21. The limiting assembly 3 also includes a return spring 33 arranged in the shell 31 and sleeved on the outside of the plug-in 32. The upper part of the insertion end of the plug-in 32 is set as a slope, and the two sides of the bottom of the column 21 are also set as slopes. When the base 1 is docked with the support frame 2 or the two support frames 2 are docked, the slope on the column 21 can press downward to move the plug-in 32 outward until the plug-in 32 can be inserted into the slot 22.

[0031] When the base 1 and support frame 2 are docked, or when two support frames 2 are docked, the pin 21 begins to insert into the corresponding slot (first slot 11 or second slot 23). During insertion, the inclined surface at the bottom of the pin 21 first contacts the inclined surface at the insertion end of the insert 32. Due to the action of the inclined surface, the pin 21 presses downward on the insert 32, applying an outward horizontal force to the insert 32, causing it to move outward and compressing the return spring 33. As the pin 21 continues to insert, when the insert 32 aligns with the slots 22 on either side of the pin 21, the elastic restoring force of the return spring 33 causes the insert 32 to move inward and insert into the slots 22. At this point, the insert 32 engages the slots 22, locking the pin 21 in place within the slot, thereby firmly securing the base 1 and support frame 2, or between two adjacent support frames 2, preventing loosening or separation during use and ensuring normal production.

[0032] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
