Technical Field

[0001] This utility model relates to the field of textile processing technology, and in particular to a circular knitting machine for preventing yarn breakage. Background Technology

[0002] Circular knitting machines, also known as circular knitting weft knitting machines or circular knitting weft machines, have seen rapid development due to their numerous yarn feed paths, high speed, high output, rapid pattern changes, good fabric quality, fewer processes, and strong product adaptability.

This invention provides a yarn tensioning mechanism for a circular knitting machine to solve the problem that in the prior art, a yarn tensioning mechanism is needed to assist the circular knitting machine in knitting yarn, but most existing yarn tensioning mechanisms do not have the ability to adjust the yarn tension and cannot well meet the usage requirements.

[0004] The existing technology has the following problems:

[0005] The tensioning mechanism uses torsion springs to passively adjust the yarn tension. However, the lifespan of the torsion springs decreases with long-term use, and their elasticity is also affected. When the yarn tension is too high, they may break, making it difficult to actively adjust the yarn tension and improve production yield. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5As shown, a circular knitting machine for preventing yarn breakage includes a circular knitting machine body 1. A control mechanism 2 is movably installed on the front side of the circular knitting machine body 1. A fixed platform 3 is movably installed on the upper side of the circular knitting machine body 1. Several ring-shaped tensioning mechanisms 4 are overlapped on the upper side of the fixed platform 3. Two fixed mechanisms 5 are fixedly connected to the upper side of each of the tensioning mechanisms 4. The lower side of the fixed mechanism 5 is fixedly connected to the upper side of the fixed platform 3.

[0027] The tensioning mechanism 4 includes a base plate 41. Two rotating rods 43 are rotatably connected to the upper side of the base plate 41 near the inner side of the fixed platform 3. A tensioning wheel 45 is rotatably connected to the upper end of the rotating rod 43. Two electromagnetic telescopic rods 47 are rotatably connected to both sides of the tensioning wheel 45. The lower end of the electromagnetic telescopic rod 47 is rotatably connected to the upper side of the base plate 41 away from the inner side of the fixed platform 3. A tension monitoring component 46 is movably installed on the upper side of the base plate 41 near the inner side of the fixed platform 3.

[0028] It should be noted that the tension monitoring component 46 contains a three-pulley tension sensor, which can detect the tension of the yarn. The electromagnetic telescopic rod 47 is a device that uses electromagnetic effect to achieve telescopic movement, so that the length of the electromagnetic telescopic rod 47 can be adjusted, thereby changing the height of the tensioning wheel 45, which in turn adjusts the tension of the yarn. The base plate 41 and the fixed platform 3 are electrically connected in the form of contacts. The tension monitoring component 46 detects the yarn tension and then transmits the result to the control mechanism 2. The control mechanism 2 processes the result and then transmits a signal to the electromagnetic telescopic rod 47 to control the length adjustment of the electromagnetic telescopic rod 47.

[0029] like Figure 3 As shown, two guide wheels 44 are rotatably connected to the upper side of the substrate 41 away from the inner side of the fixed platform 3, and a tension wheel 45 is located between the two guide wheels 44. Two fixed pulleys 42 are rotatably connected to the upper side of the substrate 41 away from the inner side of the fixed platform 3, and the two guide wheels 44 are located between the two fixed pulleys 42.

[0030] It should be noted that the guide wheel 44 is used to ensure that the state of the yarn before or after leaving the tension wheel 45 does not change due to the change in the position of the tension wheel 45, and the fixed pulley 42 is used to lift the yarn so that the yarn does not fall onto the base plate 41.

[0031] like Figure 5As shown, the fixing mechanism 5 includes a locking platform 51. The outer side of the base plate 41 is located on the lower side of the upper wall of the locking platform 51. The lower side of the locking platform 51 is fixedly connected to the upper side of the fixing platform 3. Several linearly distributed balls 52 are movably sleeved on the side wall of the locking platform 51 near the electromagnetic telescopic rod 47. The outer side of the balls 52 is movably sleeved in the slots opened on both sides of the base plate 41 near the tension wheel 45. A baffle 53 is movably sleeved on the inner side of the locking platform 51. Several linearly distributed spherical grooves 54 are opened on the side of the baffle 53 near the tension wheel 45.

[0032] It should be noted that in the initial state, the positions of the spherical groove 54 and the ball 52 are arranged alternately. When the ball 52 is movably sleeved in the slot and the position of the baffle 53 does not change, the baffle 53 fixes the ball 52, causing the ball 52 to fix the substrate 41. Pushing the baffle 53 causes the spherical groove 54 to align with the ball 52, so that the substrate 41 can be taken out from the lower side of the upper wall of the mounting plate 51.

[0033] like Figure 5 As shown, a number of rectangularly distributed vertical plates 55 are fixedly connected to the side of the baffle 53 near the tension wheel 45. Limiting rods 56 are movably sleeved on the inner side of each vertical plate 55. The two ends of the limiting rods 56 are fixedly connected to the vertical surface inside the mechanism groove opened on the inner side of the clamping table 51 near the tension wheel 45. Springs 57 are movably sleeved on the outer side of each limiting rod 56, and the springs 57 are located on the side of the vertical plate 55 near the inner side of the fixed table 3.

[0034] It should be noted that the spring 57 pushes the vertical plate 55 so that the initial state of the vertical plate 55 will not be changed by external non-human operation.

[0035] like Figure 4 As shown, the side of the clamping platform 51 away from the tensioning wheel 45 has several horizontally distributed limiting grooves 58, and the round shaft of the baffle 53 away from the tensioning wheel 45 is movably sleeved in the limiting grooves 58.

[0036] It should be noted that the limiting groove 58 is used to limit the movement range of the baffle 53, so that the spherical groove 54 can be aligned with the ball 52. A push plate is provided on the side of the round shaft away from the ball 52, and the baffle 53 can be pushed by pushing the push plate.

[0037] like Figure 3 As shown, a push plate 59 is fixedly connected to the upper side of the substrate 41 near the card table 51.

[0038] It should be noted that when the thumb pushes the baffle 53, the other fingers can push the push plate 59, which makes it easier to remove the substrate 41.

[0039] like Figure 4As shown, a limiting block 510 is fixedly connected to the upper side of the card table 51 away from the inner side of the fixed table 3, and the side of the limiting block 510 is in contact with the surface of the push plate 59 near the inner side of the fixed table 3.

[0040] It should be noted that the limiting block 510 is used to limit the push plate 59. When the push plate 59 contacts the limiting block 510 during the installation of the substrate 41, it indicates that the substrate 41 is installed in place.

[0041] The working principle of this utility model is as follows: First, the tension monitoring component 46 contains a three-pulley tension sensor, which can detect the tension of the yarn. The electromagnetic telescopic rod 47 is a device that uses electromagnetic effect to achieve telescopic movement, so that the length of the electromagnetic telescopic rod 47 can be adjusted, thereby changing the height of the tensioning wheel 45, which in turn adjusts the tension of the yarn. The base plate 41 and the fixed platform 3 are electrically connected by contacts. The tension monitoring component 46 detects the yarn tension and then transmits the result to the control mechanism 2. The control mechanism 2 processes the result and then transmits a signal to the electromagnetic telescopic rod 47 to control the length adjustment of the electromagnetic telescopic rod 47. The guide wheel 44 is used to ensure that the state of the yarn before or after leaving the tensioning wheel 45 does not change due to the change of the position of the tensioning wheel 45. The fixed pulley 42 is used to lift the yarn so that the yarn does not fall onto the base plate 41. The tension monitoring component 46 detects the tension of the yarn, so that the electric... The length of the magnetic telescopic rod 47 is adjusted to adjust the height of the tensioning wheel 45, thereby actively adjusting the yarn tension to keep it within a certain range and improve product yield. Initially, the spherical groove 54 and the ball bearing 52 are alternately positioned. When the ball bearing 52 is movably engaged in the slot, and the position of the baffle 53 remains unchanged, the baffle 53 fixes the ball bearing 52, thus fixing the ball bearing 52 to the base plate 41. Pushing the baffle 53 aligns the spherical groove 54 with the ball bearing 52, allowing the base plate 41 to be removed from the lower side of the upper wall of the mounting platform 51. The spring 57 pushes the vertical plate 55, ensuring that the initial state of the vertical plate 55 is not altered by external, non-human operation. When the ball bearing 52 is in the slot, it fixes the base plate 41. Pushing the rotating rod 43 allows the ball bearing 52 to disengage from the slot, allowing the base plate 41 to be removed from the lower side of the upper wall of the mounting platform 51. This facilitates maintenance of the tensioning mechanism 4, making installation and disassembly convenient.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
