Description

Technical Field

[0001] The utility model relates to the technical field of flat knitting machines, in particular to a winding mechanism of a flat knitting machine. Background Art

[0002] A knitting machine is a mechanical device used to produce knitwear. It converts yarn into various knitwear such as clothes, socks, hats, etc. through continuous horizontal knitting action. The core working principle of a knitting machine is to use the knitting needle to reciprocate in the horizontal direction, and drive the yarn to form a knitted structure through the up and down movement of the knitting needle. The characteristic of this structure is that it can well maintain the elasticity and softness of the fabric, making the knitwear more comfortable and fit when worn. Knitting machines are usually equipped with a multi-channel needle selection system, which can selectively activate or shut down certain knitting needles according to different knitting procedures and design requirements, thereby achieving complex and diverse knitting patterns and textures. With the development of technology, modern knitting machines have achieved a high degree of automation and electrification, and can control the knitting process through computer programming, greatly improving production efficiency and product quality. In addition, knitting machines also have environmental protection characteristics such as energy saving and emission reduction, which is in line with the concept of sustainable development. In the textile industry, knitting machines are widely used. They can not only produce traditional knitted clothing, but also customize various functional knitwear according to special needs, such as sportswear, medical supplies, etc. With the rise of personalization and customization, the flexibility and diversity of knitting machines have made them play an increasingly important role in the modern textile industry.

[0003] However, the current knitting machines, after weaving the fabric, will directly drop it into the receiving slot at the bottom of the machine body. The operator cuts the fabric in batches, thereby obtaining batches of fabric for stacking and collecting. Finally, the operator takes the whole batch of fabric away for shipment or subsequent processing. However, the current knitting machines also require that there is always an operator squatting in front of its receiving slot to manually cut and take away the fabric in batches. For knitting machines with a high degree of automation and the need to produce fabrics around the clock, there is naturally a gap in work efficiency between the two, resulting in the inability of manpower to keep up with the efficiency of knitting machines in shipping.

[0004] Therefore, a knitting machine winding mechanism is proposed to solve or alleviate the above problems. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] A winding mechanism for a flat knitting machine, such as Figure 1 As shown, it includes a body 1, the front side of the body 1 is recessed inward to form a receiving slot that can be opened and closed. Specifically, a door 2 for closing the receiving slot is hinged on the body 1, and a winding mechanism is arranged in the receiving slot. The winding mechanism guides the outside air to enter radially and circulate along its length direction.

[0026] like Figure 2 and 3As shown, the winding mechanism includes a hollow winding roller 4, one end of which is connected to a rotating air extraction component, a bearing seat 3 is fixedly connected to the inner wall of the receiving groove, the winding roller 4 is fixedly connected to the inner ring of the bearing seat 3, and the end of the winding roller 4 away from the rotating air extraction component is transmission-connected to a driving motor arranged on the machine body 1, a plurality of air extraction holes 401 connected to the interior thereof are opened on the outer peripheral wall of the winding roller 4, the aperture of the air extraction holes 401 is gradually reduced from the inside to the outside, and the air extraction holes 401 are truncated cone-shaped, the rotating air extraction component is connected to a vertically arranged connecting pipe 1 601, and the connecting pipe 1 601 is connected to a horizontally arranged connecting pipe 2 603 through a bellows 602, and the connecting pipe 2 603 is used to connect to an air extraction pump.

[0027] like Figure 4 and 5 As shown, the rotary air extraction assembly includes two end plates 5, a cylinder wall 501 fixedly connected to the two end plates 5 and facing each other, a plurality of connecting pieces 502 fixedly connected between the cylinder walls 501 on both sides, and a rotating sleeve 6 sleeved on the outside of the cylinder wall 501 and covering the connecting pieces 502. The outer diameter of the cylinder wall 501 is smaller than the outer diameter of the end plate 5, and the rotating sleeve 6 is fixedly connected to the connecting pipe 601 and connected. The opening cross-sectional area formed between adjacent connecting pieces 502 and the inner cross-sectional area of ​​the connecting pipe 601 are larger than that of the winding roller 4. The inner cross-sectional area, the outer ring of the cylinder wall 501 is recessed inward to form a plurality of recessed holes 5011, a retaining ring 503 is sleeved on the outer side of the cylinder wall 501, and a ball 5031 is movably connected in the recessed hole 5011. The retaining ring 503 is provided with limiting holes corresponding to the recessed holes 5011 and for the ball 5031 to pass through. The inner ring of the rotating sleeve 6 is provided with an annular groove for accommodating the ball 5031 protruding from the retaining ring 503. A sealing ring 7 is embedded between the rotating sleeve 6 and the end plate 5 and is sleeved on the outer side of the cylinder wall 501. The sealing ring 7 is a sealing rubber ring.

[0028] When the utility model is working, the knitting machine completes the weaving of the yarn, so that the textile can enter the receiving slot through the frame. At this time, it is only necessary to start the suction pump to allow suction through the connecting pipe 2 603, the bellows 602, and the connecting pipe 1 601 in order to exhaust air into the rotating exhaust component. Since the opening cross-sectional area formed between the adjacent connecting pieces 502 and the inner cross-sectional area of ​​the connecting pipe 1 601 are both larger than the inner cross-sectional area of ​​the winding roller 4, when the air in the winding roller 4 and the exhaust hole 401 is sucked, the air there can increase the flow rate, thereby further reducing the air pressure there, so that the external atmospheric pressure can press the textile onto the winding roller 4. When the driving motor drives the winding roller 4 to rotate, the winding roller 4 can be supported and rotated smoothly through the bearing seat 3. In this way, the winding roller 4 can realize winding of the textile entering the receiving slot. After completing the winding work, the operator opens the box door 2 and unwinds the textile from the winding roller 4.

[0029] During the rotation of the winding roller 4, the winding roller 4 will also drive the end plate 5 to rotate. During the rotation of the end plate 5, the cylinder wall 501 and the connecting piece 502 will be driven to rotate together, while the rotating sleeve 6 and the connecting tube 601 remain stationary, thereby realizing the relative rotation of the rotating sleeve 6 and the end plate 5, the cylinder wall 501, and the connecting piece 502. In addition, during the rotation, due to the setting of the ball 5031, the rotation of the rotating sleeve 6 is relatively smooth. At the same time, the retaining ring 503 can limit the ball 5031 to prevent it from falling. Finally, the sealing ring 7 seals the gap between the rotating sleeve 6 and the end plate 5, so that during the relative rotation of the rotating sleeve 6, there will be no leakage between the rotating sleeve 6 and the cylinder wall 501, the end plate 5, and the connecting piece 502, thereby ensuring that the air is completely sucked out.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
