Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a conveniently detachable fastener for a large circular knitting machine. Background Technology

[0002] "Circular knitting machine" is a common name for a core production equipment in the knitting industry. Its formal name is usually single-sided circular knitting machine or double-sided circular knitting machine, and sometimes it is simply called a circular knitting machine. It is used to continuously and efficiently produce tubular knitted fabrics. The knitting disc (also called needle disc or large disc) of the circular knitting machine is one of the core components of the circular knitting machine (circular weft knitting machine). It is responsible for fixing the knitting needles, controlling the movement trajectory of the needles, and cooperating with the loop forming system to complete the knitting of the fabric. The lower surface of the knitting disc of the circular knitting machine is equipped with several fixing parts. The knitting disc of the circular knitting machine is connected to the machine body through the fixing parts, so that the knitting disc can be firmly locked to the machine body of the circular knitting machine to prevent it from shaking during operation and affecting the knitting accuracy.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: the existing fasteners are integrally formed by mold casting. When adjusting the height of the knitting disc, the entire fastener often has to be removed and replaced with another fastener that matches the height of the knitting disc. The base position needs to be repositioned, and the adjustment process is complicated and cumbersome. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a convenient and easy-to-disassemble fastener for large circular knitting machines that is easy to adjust and does not require repeated positioning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a conveniently detachable fastener for a large circular knitting machine, comprising a base and a support column detachably mounted on the upper surface of the base by bolts, wherein the bottom end of the support column is integrally formed with a first threaded hole, the base comprises a base body and a second threaded hole that penetrates and is integrally formed on the base body at the position corresponding to the first threaded hole, and a third threaded hole for fixing the base body is also provided on the base body.

[0006] A further improvement is that an extension block is welded and fixed to the top of the support column.

[0007] A further improvement is that the extension block has several fourth threaded holes integrally formed therethrough.

[0008] A further improvement is that the bottom end of the second threaded hole is integrally formed with a bolt positioning groove.

[0009] After adopting the above technical solution, the beneficial effects of this utility model are as follows: In the process of using this utility model, if it is necessary to adjust the height of the knitting disc of the circular knitting machine, the bolts can be unscrewed from the first threaded hole and the second threaded hole to make the base and the support no longer fixedly connected, thereby replacing the support. When the support is replaced to match the height of the knitting disc, there is no need to reposition it. It is only necessary to lock the replaced support back into the base fixed on the main body of the circular knitting machine. Disassembly, replacement and adjustment are convenient.

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0015] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is: a conveniently detachable fixing component for a large circular knitting machine, including a base 2 and a support column 1 detachably mounted on the upper surface of the base 2 by bolts. The bottom end of the support column 1 is integrally formed with a first threaded hole 11. The base 2 includes a base body 21 and a second threaded hole 22 penetrating and integrally formed on the base body 21 at the position corresponding to the first threaded hole 11. The base body 21 is also provided with a third threaded hole 23 for fixing the base body 21. In use, firstly, a support column 1 that matches the height of the knitting tray is selected. The support column 1 can be a cast iron part or a stamped metal tube. The base 2 is placed on the main body of the large circular knitting machine. After positioning, it is placed under the knitting tray that meets the requirements. The base 2 is fixed to the main body of the large circular knitting machine by screwing in the bolt through the third threaded hole 23. Then, the support column 1 is removed, and the first threaded hole 11 at the bottom of the support column 1 is aligned with the second threaded hole 22 on the base 2. The second threaded hole 23 is screwed in by screwing in the bolt. The threaded hole 22 allows the bolt to move along the second threaded hole 22 into the first threaded hole 11, thereby connecting the base 2 and the support column 1. At this time, the support column 1 can support the knitting tray of the circular knitting machine. When adjusting the height of the knitting tray, first suspend the knitting tray to the required height and fix it. Then, take out the support column 1 that matches the height of the knitting tray, and simultaneously loosen or tighten the bolts that pass through the second threaded hole 22 and the first threaded hole 11 to remove it. At this time, the support column 1 that needs to be replaced can be removed from the base 2. Then, the support column 1 that matches the height of the knitting tray can be taken out immediately, and the first threaded hole 11 at the bottom of the support column 1 that matches the height of the knitting tray is aligned with the second threaded hole 22. The bolts are then locked into the second threaded hole 22 and the first threaded hole 11 again, so that the support column 1 that matches the height of the knitting tray is fixed on the base 2. When replacing, there is no need to reposition it. Just lock the replaced support column 1 back into the base 2 fixed on the main body of the circular knitting machine. Disassembly, replacement and adjustment are convenient.

[0016] An extension block 3 is also welded and fixed to the top of the support column 1, which helps to increase the contact area between the top of the support column 1 and the knitting disc, thereby improving the support stability and support effect.

[0017] The extension block 3 has several fourth threaded holes 31 integrally formed on it, which facilitates the bolts to be locked into the knitting disc through the fourth threaded holes 31, thereby further improving the fixing effect of the extension block 3 on the knitting disc.

[0018] The bottom end of the second threaded hole 22 is integrally formed with a bolt positioning groove 221, which makes it easier to locate the second threaded hole 22 when it is not visible to the naked eye, and facilitates the insertion of the bolt into the second threaded hole 22.

[0019] The working principle of this utility model is as follows: First, select a support column 1 that matches the height of the knitting disc. Place the base 2 on the main body of the circular knitting machine. After positioning, place it below the knitting disc as required. Secure the base 2 to the main body of the circular knitting machine by screwing in a bolt through the third threaded hole 23. Then, remove the support column 1 and align the first threaded hole 11 at the bottom of the support column 1 with the second threaded hole 22 on the base 2. Screw in the bolt through the second threaded hole 22, allowing the bolt to move along the second threaded hole 22 into the first threaded hole 11, thus connecting the base 2 and the support column 1. At this point, the support column 1 can support the knitting disc of the circular knitting machine. When adjusting the height of the knitting disc, first suspend the knitting disc and move it to... After fixing the required height, remove the support column 1 that matches the height of the knitting disc, and simultaneously loosen or tighten the bolts inserted into the second threaded hole 22 and the first threaded hole 11 to remove it. At this point, the support column 1 that needs to be replaced can be removed from the base plate 2. Then, immediately remove the support column 1 that matches the height of the knitting disc, align the first threaded hole 11 at the bottom of the support column 1 with the second threaded hole 22, and re-lock the bolts into the second threaded hole 22 and the first threaded hole 11, so that the support column 1 that matches the height of the knitting disc is fixed on the base 2. When replacing, there is no need to reposition it; simply lock the replaced support column 1 back into the base 2 fixed on the main body of the circular knitting machine. Disassembly, replacement, and adjustment are convenient.
