Description

Technical Field

[0001] The utility model belongs to the technical field of large circular knitting machines, in particular to an anti-vibration frame of a large circular knitting machine. Background Art

[0002] Large circular knitting machine, scientifically known as circular weft knitting machine, is mainly composed of a frame, a yarn supply mechanism, a transmission mechanism, a lubrication and dust removal mechanism, an electrical control mechanism, a pulling and winding mechanism and other auxiliary devices. Large circular knitting machines can be divided into two categories: single-sided series and double-sided series. Due to the large circular knitting machine's multiple loop forming systems, high speed, high output, fast pattern changes, good fabric quality, fewer processes, and strong product adaptability, it has developed rapidly. Among them, the double-sided knitting large circular machine is a large circular machine with two needle cylinders.

[0003] When the existing circular knitting machine is started, the circular knitting machine itself will produce a certain vibration. At this time, if the circular knitting machine is placed on the ground for work, the vibration of the circular knitting machine itself may cause itself to move slightly, causing the yarn winding of the circular knitting machine itself to be affected, thereby affecting the working operation of the equipment itself. Therefore, we proposed a double-sided circular knitting machine anti-vibration frame to solve this problem. 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 accompanying drawings in the embodiments of the present invention.

[0025] See also Figure 1-4 As shown, the utility model is a vibration-proof frame of a large circular knitting machine, including a knitting body 3 and support columns 1 evenly distributed directly below the knitting body 3, and also includes:

[0026] The connecting columns 2 are evenly distributed and fixed on the lower end surface of the braided body 3, and the connecting columns 2 and the supporting columns 1 maintain a unified vertical center line;

[0027] The airbag sphere 11 is arranged between the connecting column 2 and the supporting column 1, and the upper and lower ends of the airbag sphere 11 are respectively fixedly connected to the bottom of the connecting column 2 and the top of the supporting column 1. A certain amount of gas is arranged inside the airbag sphere 11, and the whole can withstand a large pressure, and can play a role of shock absorption and buffering when the braided main body 3 vibrates up and down;

[0028] The limiting component is arranged outside the supporting column 1, and plays a guiding role in the vibration direction of the connecting column 2. The limiting component includes a guiding groove 4 and a sliding sleeve 5. The guiding groove 4 is evenly distributed and opened on the outer wall of the supporting column 1. The sliding sleeve 5 is fixed to the outside of the connecting column 2, and the sliding sleeve 5 is slidably connected to the inside of the guiding groove 4. The sliding sleeve 5 can slide up and down along the linear direction of the guiding groove 4 when the connecting column 2 vibrates up and down, so as to limit the vibration direction of the connecting column 2, so that when it vibrates up and down, the direction of the connecting column 2 squeezing the airbag ball 11 downward is more stable;

[0029] The shock-absorbing component is circumferentially arranged on the outside of the limiting component and is used to reduce shock to the braided main body 3. The shock-absorbing component includes a connecting plate 6, a rotating arm 1 8, a rotating arm 2 9 and a sleeve 10. The rotating arm 1 8 is circumferentially distributed and rotatably connected to the outer wall of the connecting column 2, and the rotating arm 2 9 is circumferentially distributed and rotatably connected to the outer wall of the supporting column 1. The connecting plate 6 is circumferentially arranged on the outside of the sliding sleeve 5, and the upper and lower ends of the connecting plate 6 are respectively rotatably connected to the rotating arm 1 8 and the rotating arm 2 9. The sleeve 10 is rotatably connected to the inner center position of the connecting plate 6. The internal sliding clamp of the sleeve 10 is connected with a damper 13, and one end of the damper 13 is rotatably connected to the sliding sleeve 5. The outer sleeve of the damper 13 is provided with a tension spring 12, and the tension spring 12 is provided on the outer sleeve of the damper 13. The spring 12 is located inside the sleeve 10, and the sleeve 10 is used to install the tension spring 12. The tension spring 12 can generate a certain pulling force on the damper 13, and then the damper 13 can pull the external connecting plate 6 toward the sliding sleeve 5. The rotating arm 1 8 and the rotating arm 2 9 can maintain a certain angle under the pulling action of the damper 13, and then cooperate with the buffering effect of the airbag ball 11 to achieve the shock absorbing effect on the overall equipment to avoid problems with the textile fabric due to vibration. A shock absorbing layer 7 is provided at the bottom of the support column 1, and the lower end surface of the shock absorbing layer 7 is in contact with the ground. The shock absorbing layer 7 is made of a relatively soft material, which can absorb energy during the vibration of the equipment.

[0030] Working principle: First, the connecting column 2 is evenly distributed and fixed on the lower end surface of the braided main body 3 to support the braided main body 3. The airbag sphere 11 is provided with a certain amount of gas inside, which can withstand a large pressure as a whole and play a role of shock absorption and buffering when the braided main body 3 vibrates up and down;

[0031] Then, the tension spring 12 is set to generate a certain pulling force on the damper 13, and then the damper 13 can pull the external connecting plate 6 toward the sliding sleeve 5. Under the pulling action of the damper 13, the rotating arm 1 8 and the rotating arm 2 9 can maintain a certain angle, and combined with the buffering effect of the airbag ball 11, the shock absorbing effect of the overall equipment is achieved to avoid problems with textile fabrics caused by vibration.
