Description

Technical Field

[0001] This utility model relates to the field of computerized flat knitting machine technology, specifically to a computerized flat knitting machine with a bobbin positioning structure. Background Technology

[0002] Computerized flat knitting machines (also known as electronic flat knitting machines or knitting machines) are automated mechanical devices used for knitting fabrics. They are widely used in the textile industry and are operated by a horizontally placed needle bed and a computer control system.

[0003] Chinese Patent Announcement No. CN218321836U discloses a stable lead wire mechanism for a computerized flat knitting machine. This patent prevents the yarn from being too taut during lead wire laying by using a second winding wheel and a rotating frame. In this way, the chance of yarn breakage is reduced and the knitting efficiency of the computerized flat knitting machine is improved while the machine is knitting.

[0004] In existing technologies, since the first and second winding wheels guide the yarn path, the lack of positioning of the yarn bobbin can easily lead to unstable yarn paths, resulting in problems such as winding deviation and uneven tension, thus affecting the normal use of the device.

[0005] Based on this, this utility model designs a computerized flat knitting machine with a bobbin positioning structure to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a computerized flat knitting machine with a bobbin positioning structure.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A computerized flat knitting machine with a bobbin positioning structure includes a machine body and support rods. Multiple support rods are fixedly connected to the bottom of the machine body. A support frame is provided on the upper surface of the machine body. An adjustment assembly is provided on the outer surface of the support frame, and a positioning assembly is provided on the outer surface of the adjustment assembly. The adjustment assembly includes a pair of adjustment frames symmetrically mounted on the outer surface of the support frame. An electric push rod is fixedly connected inside each of the two adjustment frames. An adjustment block is fixedly connected to the output shaft end of each electric push rod. A moving block is fixedly connected between the two adjustment blocks. The positioning assembly includes multiple base plates fixedly mounted on the upper surface of the moving block. A winding rod is provided on the upper surface of each base plate. A fixing plate is threadedly connected to the outer surface of the winding rod. Multiple side plates are fixedly connected to the upper surface of the moving block. A sliding rod is slidably connected inside each side plate, and an arc-shaped clamping plate is fixedly connected to one end of each sliding rod.

[0009] Furthermore, both of the adjustment frames have movable grooves on their outer surfaces.

[0010] Furthermore, the moving block is slidably connected to the inside of the moving groove, and the adjusting block is slidably connected to the inside of the adjusting frame.

[0011] Furthermore, a spring is fitted onto the outer surface of the slide rod, with one end of the spring connected to the arc-shaped clamp and the other end connected to the side of the side plate.

[0012] Furthermore, silicone pads are fixedly connected to the outer surface of the arc-shaped clamps, and a limit plate is fixedly connected to the other end of the slide rod.

[0013] Furthermore, a fixing rod is provided between the support frames, and multiple winding wheels are fixedly connected to the outer surface of each fixing rod.

[0014] Furthermore, the upper surface of the computer flat knitting machine body is fixedly connected to two mounting slots, and a magnet is fixedly connected inside the mounting slots. A second magnet is magnetically connected to the upper surface of the first magnet.

[0015] Furthermore, the upper surface of the magnet is connected to the support frame, and the mounting groove and the support frame are provided with threaded holes, and expansion bolts are threaded into the threaded holes. Beneficial effects

[0016] This design places the bobbin on the winding rod, ensuring its free rotation. A base plate and a rotating fixing plate securely fix the bobbin to the winding rod, preventing it from loosening during operation. The yarn is guided through multiple winding wheels, while an arc-shaped clamp automatically adjusts the pressure via springs to maintain appropriate tension. This ensures that the arc-shaped clamp and silicone pad remain in contact with the yarn, guaranteeing yarn path stability, reducing the risk of winding deviation, and preventing problems such as unstable yarn path, winding deviation, and uneven tension caused by a lack of bobbin positioning.

[0017] The electric push rod extends and retracts, pushing the adjusting block to slide inside the adjusting frame. At the same time, the moving block moves synchronously with the adjusting block through a sliding connection with the moving groove. This allows the position of the yarn to be adjusted as needed, thereby controlling its tension and avoiding the problem of unstable yarn path. This enables rapid adjustment according to different sizes and types of bobbins, improving the machine's versatility and adaptability.

[0018] By using magnet one, magnet two, and the mounting groove together, the support frame can be quickly installed and disassembled with the computerized flat knitting machine body, allowing for rapid adjustments according to work requirements. At the same time, the threaded holes and expansion bolts ensure the stability of the support frame during long-term use, preventing loosening due to vibration or other external factors.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-7 A computerized flat knitting machine with a bobbin positioning structure includes a computerized flat knitting machine body 1 and support rods 101. Multiple support rods 101 are fixedly connected to the bottom of the computerized flat knitting machine body 1. A support frame 102 is provided on the upper surface of the computerized flat knitting machine body 1. An adjustment component 2 is provided on the outer surface of the support frame 102.

[0035] In this embodiment of the utility model, the adjustment component 2 includes a pair of adjustment frames 201 symmetrically installed on the outer surface of the support frame 102. An electric push rod 202 is fixedly connected inside each of the two adjustment frames 201. An adjustment block 203 is fixedly connected to the output shaft end of the electric push rod 202. A moving block 205 is fixedly connected between the two adjustment blocks 203. A moving groove 204 is opened on the outer surface of each of the two adjustment frames 201. The moving block 205 is slidably connected to the inside of the moving groove 204, and the adjustment block 203 is slidably connected to the inside of the adjustment frame 201.

[0036] In one embodiment of this utility model, the electric push rod 202 is activated, causing the electric push rod 202 to extend and retract, and pushing the adjusting block 203 to slide along the inside of the adjusting frame 201. The moving block 205 is slidably connected with the moving groove 204 and moves synchronously with the moving adjusting block 203 so as to adjust the position of the yarn as needed.

[0037] In some embodiments, such as Figure 1-7 As shown, in a preferred embodiment of the present invention, the outer surface of the adjusting component 2 is provided with a positioning component 3.

[0038] In this embodiment of the utility model, the positioning component 3 includes multiple base plates 301 fixedly installed on the upper surface of the movable block 205. A winding rod 302 is provided on the upper surface of the base plate 301. A fixing plate 303 is threadedly connected to the outer surface of the winding rod 302. Multiple side plates 304 are fixedly connected to the upper surface of the movable block 205. A sliding rod 305 is slidably connected inside each side plate 304. An arc-shaped clamping plate 306 is fixedly connected to one end of the sliding rod 305. A spring 307 is sleeved and connected to the outer surface of the sliding rod 305. One end of the spring 307 is connected to the arc-shaped clamping plate 306, and the other end is connected to the side of the side plate 304. A silicone pad 308 is fixedly connected to the outer surface of each arc-shaped clamping plate 306. A limit plate is fixedly connected to the other end of the sliding rod 305. A fixing rod 309 is provided between the support frames 102. Multiple winding wheels 310 are fixedly connected to the outer surface of each fixing rod 309.

[0039] In one embodiment of this utility model, a bobbin is fitted onto a winding rod 302 to ensure that the bobbin can rotate freely. A fixing plate 303 securely fixes the bobbin to the winding rod 302 via threads on its surface to prevent it from loosening during operation. The yarn is then guided through multiple winding wheels 310. When the yarn begins to move, the arc-shaped clamp 306 automatically adjusts the pressure through the action of a spring 307 to maintain appropriate tension. Simultaneously, the required knitting pattern, color combination, stitch type, and other parameters are input into the control system of the computerized flat knitting machine. After confirming that all settings are correct, the settings are saved and the knitting process is prepared to begin. At the same time, when the winding rod 302 releases yarn, the arc-shaped clamp 306 and the silicone pad 308 are kept in contact with the yarn through the cooperation of the slide bar 305 and the spring 307.

[0040] In some embodiments, such as Figure 1-7 As shown, this is a preferred embodiment of the present invention.

[0041] In this embodiment of the utility model, two mounting slots 4 are fixedly connected to the upper surface of the computer flat knitting machine body 1. A magnet 401 is fixedly connected inside the mounting slot 4. A magnet 402 is magnetically connected to the upper surface of the magnet 401. The upper surface of the magnet 402 is connected to the support frame 102. Threaded holes 403 are opened inside the mounting slots 4 and the support frame 102. An expansion bolt 404 is threaded inside the threaded hole 403.

[0042] In one embodiment of this utility model, the support frame 102 is placed on the upper surface of the computer flat knitting machine body 1, ensuring that the support frame 102 is aligned with the mounting groove 4, so that the first magnet 401 and the second magnet 402 are magnetically connected, initially fixing the support frame 102. Then, the expansion bolts 404 are used to further reinforce the support frame 102 through the threaded holes 403 to ensure its stability. Conversely, the support frame 102 can be disassembled so that it can be quickly installed or disassembled according to work requirements.

[0043] The working principle of this utility model is as follows: When in use, first place the support frame 102 on the upper surface of the computer flat knitting machine body 1, ensuring that the support frame 102 is aligned with the mounting groove 4, so that the first magnet 401 and the second magnet 402 are magnetically connected, initially fixing the support frame 102. Then, use expansion bolts 404 through threaded holes 403 to further reinforce the support frame 102 to ensure its stability. Conversely, the support frame 102 can be disassembled so that it can be quickly installed or disassembled according to work requirements.

[0044] Then, turn on the control system of the computer-controlled flat knitting machine body 1, enter the bobbin positioning and adjustment interface, select the bobbin number to be adjusted (if there are multiple bobbins), and input the required adjustment distance or position. The control system then sends a command to the electric push rod 202, which begins to extend and retract, pushing the adjusting block 203 to slide along the inside of the adjusting frame 201. The moving block 205, through its sliding connection with the moving groove 204, moves synchronously with the adjusting block 203, thereby adjusting the yarn position as needed to control its tension and...

[0045] Subsequently, the bobbin is placed on the winding rod 302, ensuring that the bobbin can rotate freely. The fixing plate 303 securely fixes the bobbin to the winding rod 302 through the threads on the surface of the winding rod 302 to prevent it from loosening during operation. The yarn is then guided through multiple winding wheels 310. When the yarn begins to move, the arc-shaped clamp 306 automatically adjusts the pressure through the action of the spring 307 to maintain appropriate tension. At the same time, the required knitting pattern, color combination, stitch type and other parameters are input into the control system of the computer flat knitting machine. After confirming that all settings are correct, the settings are saved and ready to start knitting. Meanwhile, when the winding rod 302 releases the yarn, the arc-shaped clamp 306 and the silicone pad 308 are kept in contact with the yarn through the cooperation of the slide bar 305 and the spring 307.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
