Description

Technical Field

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

[0002] The circular knitting machine is a core piece of equipment in the textile industry used to produce knitted fabrics. It is mainly used to knit semi-finished fabrics for clothing such as underwear, sportswear, and T-shirts. The knitting disc (also called the 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 a fixing device. Through the fixing device, together with the fixing parts and bolts, the knitting disc of the circular knitting machine is connected to the machine body, 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 aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: the existing fixing device of the large circular knitting machine's knitting disc is connected to the top of the fixing component by a hexagonal bolt through a threaded hole on its bottom surface. However, during maintenance and disassembly, a wrench is needed to loosen the hexagonal bolt at the bottom. During the loosening process, the rotation trajectory of the wrench directly overlaps with the support part of the fixing component. Consequently, the wrench is blocked by the support part of the fixing component during rotation. Therefore, it is necessary to remove the wrench and readjust the angle to rotate the hexagonal bolt, making the disassembly process very inconvenient and time-consuming. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a large circular knitting machine disc fixing device that is easy to assemble and disassemble and does not easily jam the wrench.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a large circular knitting machine tray fixing device, including a tray and a placement groove integrally formed on the upper surface of the tray, wherein a plurality of first threaded holes are integrally formed on the inner side of the placement groove on the tray, and the first threaded holes penetrate the tray.

[0006] A further improvement is that the tray has an integrally formed extension block located at the outer edge of the placement slot.

[0007] A further improvement is that the extension block has several second threaded holes integrally formed on it.

[0008] A further improvement is that the tray is integrally formed with an upper raised ring at the inner edge of the placement slot.

[0009] A further improvement is that a first reinforcing rib is integrally formed on the lower surface of the tray at the corresponding position on the inner edge of the placement groove.

[0010] A further improvement is that a second reinforcing rib is integrally formed on the lower surface of the tray at the corresponding position on the outer edge of the placement groove.

[0011] The beneficial effects of this utility model after adopting the above technical solution are as follows: This utility model allows the fixing component to be connected to the fixing device by penetrating the first threaded hole of the tray and matching the second threaded hole. After placing the knitting tray in the placement slot of the tray, the hexagonal bolt can be taken out and screwed down from the top of the first threaded hole and the second threaded hole, so that its bottom end is connected to the top of the fixing component. When disassembly, inspection and maintenance are required, after disassembling the knitting tray, the hexagonal bolt can be unscrewed from the upper surface of the tray with a wrench. During the unscrewing process, the wrench will not collide with the support of the fixing component, and there is no need to pull the wrench out and readjust the angle in the middle, thereby making the disassembly process smoother and simpler, saving time.

[0014] Figure 2 This is a top view of the fixing device of this utility model. Detailed Implementation

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] See Figure 1-2As shown, the technical solution adopted in this specific embodiment is: a circular knitting machine tray fixing device, including a tray 1 and a placement groove 2 integrally formed on the upper surface of the tray 1. Several first threaded holes 11 are integrally formed on the inner side of the placement groove 2 on the tray 1. The first threaded holes 11 penetrate the tray 1. In use, multiple fixing devices need to be removed so that they are distributed around the lower surface of the knitting tray. The knitting tray of the circular knitting machine is placed on the placement groove 2 of the tray 1, and the tray 1 is placed on the top of the fixing member on the main body of the circular knitting machine. The first threaded holes 11 are aligned with the threaded holes on the top of the fixing member, and the hexagonal bolts are removed. 1. A hexagonal bolt is inserted downwards at the top, connecting the first threaded hole 11 and the threaded hole of the fastener together. By connecting multiple fasteners to multiple fasteners, the knitting disc can be fixed on the main body of the circular knitting machine. When disassembly and maintenance are required, the knitting disc is first removed from the placement slot 2. Then, the hexagonal bolt can be unscrewed from the first threaded hole 11 using a wrench from the upper surface of the tray 1. The fastener is then separated from the tray 1. During the unscrewing process, the wrench will not collide with the support of the fastener, and there is no need to remove the wrench and readjust the angle midway. This makes the disassembly process smoother and simpler, saving time.

[0017] The tray 1 is also integrally formed with an extension block 4 at the outer edge of the placement slot 2, which helps to expand the coverage area of ​​the tray 1. Thus, when placing the knitting tray, even if there is a slight offset, the knitting tray can be supported to prevent it from falling off during installation.

[0018] The extension block 4 has several integrally formed second threaded holes 41, which facilitates connection with the fastener through the second threaded holes 41 and further improves the stability of the connection.

[0019] The tray 1 is also integrally formed with an upper raised ring 21 at the inner edge of the placement slot 2. This facilitates the positioning of the knitting tray when it is inserted, making the positioning easier and simpler during installation and improving the installation accuracy.

[0020] The lower surface of the tray 1 is integrally formed with a first reinforcing rib 13 at the corresponding position of the inner edge of the placement groove 2. This helps to improve the strength of the tray 1 and prevent the placement groove 2 from being squeezed and deformed during the operation of the knitting tray, thus affecting the support effect on the knitting tray.

[0021] The lower surface of the tray 1 has a second reinforcing rib 14 integrally formed at the corresponding position on the outer edge of the placement groove 2. This helps to further improve the strength of the tray 1 and prevent the placement groove 2 from being squeezed and deformed during the operation of the knitting tray, thus affecting the support effect on the knitting tray.

[0022] The working principle of this utility model is as follows: When using this utility model, multiple fixing devices need to be removed and arranged around the lower surface of the knitting tray. The knitting tray of the circular knitting machine is placed on the placement groove 2 of the tray 1, and the tray 1 is placed on the top of the fixing component on the main body of the circular knitting machine. The first threaded hole 11 is aligned with the threaded hole at the top of the fixing component, and the hexagonal bolt is removed. The hexagonal bolt is then inserted downwards from the top of the first threaded hole 11, so that the first threaded hole 11 and the threaded hole of the fixing component are connected together by the hexagonal bolt. By connecting multiple fixing devices with multiple fixing components, the knitting tray can be fixed on the main body of the circular knitting machine. When disassembly, inspection, and maintenance are required, the knitting tray is first removed and taken out of the placement groove 2. Then, the hexagonal bolt can be unscrewed from the first threaded hole 11 by using a wrench from the upper surface of the tray 1. Then, the fixing component is separated from the tray 1. During the unscrewing process, the wrench will not collide with the support of the fixing component, and there is no need to remove the wrench midway and readjust the angle. This makes the disassembly process smoother and simpler, saving time.
