Description

Technical Field

[0001] This utility model relates to circular knitting machines, and more particularly to a dust removal mechanism for circular knitting machines. Background Technology

[0002] The top of the circular knitting machine is a ring-shaped yarn frame with multiple yarn collectors. Each collector draws and winds yarn from the spindles on the original yarn frame, then feeds the collected yarn into the needle plate of the circular knitting machine. Once the amount of yarn collected in the yarn collectors decreases to a certain level, it is re-wound and collected from the spindles. During this process, some short fibers and debris on the yarn easily detach and, mixed with dust, fall onto the yarn frame. Over time, when the yarn leaves the yarn collectors, it is also prone to being covered with dust, short fibers, and debris, causing the following problems: affecting yarn quality; and the presence of dust, short fibers, and debris on the yarn can also cause the circular knitting machine to misjudge the yarn as having knots.

[0032] Please see Figure 1 and Figure 3 A dust removal mechanism for a circular knitting machine includes a first rod 1, a housing 2, multiple second rods 3, multiple fans 4, a slip ring 5, and a motor 6.

[0033] The first rod 1 is vertical, and its bottom is used for fixed connection with the round forming machine, thereby installing the dust removal mechanism onto the round forming machine. More specifically, the bottom of the first rod 1 may have a flange.

[0034] The housing 2 is rotatably connected to the top of the first rod 1. More specifically, the first rod 1 may include a rod body 1a and a mounting sleeve 1b fixedly connected to the top of the rod body 1a. The mounting sleeve 1b is stepped and is connected to a bearing 7 via a retaining ring. The housing 2 is then connected to the outer ring of the bearing 7 via another retaining ring.

[0035] One end of each of the second rods 3 on the inner side is fixedly connected to the housing 2, and the two can be fixed by welding.

[0036] The number of fans 4 is the same as the number of second rods 3, and multiple fans 4 are fixedly connected to the second end of multiple second rods 3 on the outer side.

[0037] Please see Figure 1 In some implementations, each fan 4 is configured in one of two ways, and the configurations of multiple fans 4 are not all the same. Configuration 1: The fan 4 is in a higher position (higher here is relative to Configuration 2), with the fan blades pointing vertically downwards; Configuration 2: The fan 4 is in a lower position (lower here is relative to Configuration 1), with the fan blades tilted downwards and outwards. For example, in the attached figure, there are three fans 4 and two rods 3, with one fan 4 in Configuration 1 and the other two fans 4 in Configuration 2.

[0038] Thus, the fan 4 in setting two is used to blow dust, lint, debris, etc. outward from the yarn frame of the circular knitting machine, while the fan 4 in setting one is used to suppress the blown dust from rising upward.

[0039] Please see Figure 3 For setting one, the second rod 3 can simply be horizontal. Alternatively, the second rod 3 can be a telescopic rod, allowing adjustment of the distance between the fan 4 and the housing 2.

[0040] Please see Figure 2 For configuration two, the second rod 3 may include a first section 3a for fixed connection with the housing 2 and a second section 3b for fixed connection with the fan 4. Both the first section 3a and the second section 3b are fitted with sliding sleeves 3c. A bolt and nut fastener 3d passes between the two sliding sleeves 3c. Tightening the fastener 3d locks the two sliding sleeves 3c to the first section 3a and the second section 3b respectively, while also restricting the relative rotation between the two sliding sleeves 3c. This allows adjustment of the tilt angle of the corresponding fan 4 and the distance between the corresponding fan 4 and the housing 2.

[0041] Please see Figure 3 and Figure 4 The stationary part of the slip ring 5 is fixedly connected to the top of the first rod 1, or more specifically, it can be fixedly connected to the aforementioned mounting sleeve 1b. The power cords of multiple fans 4 are connected to the rotating part of the slip ring 5 via the housing 2. Specifically, the rotating part of the slip ring 5 has the same number of first connecting wire groups 5a as the fans 4. The first connecting wire groups 5a and the power cords of the fans 4 can be connected via terminals. The connecting wires on the stationary part of the slip ring 5 can pass through the first rod 1 and then be connected to an external power source.

[0042] In some embodiments, multiple second rods 3 are hollow and connected to the housing 2. More specifically, the outer wall of the housing 2 may have through holes for inserting the second rods 3, and the outer wall of the second rods 3 and the edge of the through holes are welded and fixed. In conjunction with the above-mentioned configuration that "the second rod 3 may include a first section 3a for fixed connection with the housing 2 and a second section 3b for fixed connection with the fan 4," both the first section 3a and the second section 3b are hollow, and the power cord first passes through the first section 3a, then through the second section 3b, and enters the housing 2.

[0043] The motor 6 is installed inside the first rod 1 or the housing 2, driving the housing 2 to rotate around the first rod 1, which in turn drives multiple fans 4 to rotate around the first rod 1. While rotating around the first rod 1, the fan 4 also rotates its own blades, which circulate and act on the yarn frame of the circular knitting machine, blowing dust, lint, debris and other particles off the yarn frame.

[0044] If motor 6 is installed on the first rod 1, then motor 6 can be installed on the outer wall of the first rod 1, and transmission between motor 6 and housing 2 is achieved through gears. Although the structure is relatively simple and compact, motor 6 and gears are exposed, making them prone to dust, lint, debris, etc.

[0045] Please see Figure 3 The motor 6 is installed inside the housing 2, and the power cord of the motor 6 is also connected to the rotating part of the slip ring 5. That is, for the rotating part of the slip ring 5, in addition to multiple sets of first connecting wires 5a, a second connecting wire set 5b is also required to connect to the motor 6. By placing the motor 6 inside the housing 2, it is isolated from external dust, lint, debris, etc., resulting in a better working environment for the motor 6.

[0046] Please see Figure 4 In conjunction with the above-mentioned "motor 6 is mounted on housing 2", furthermore, a gear ring 1b1 is fixedly provided at the top of the first rod 1, or more specifically, the top of the mounting sleeve 1b may be integrally equipped with a gear ring 1b1; the output shaft of the motor 6 is fixedly provided with a first gear 6a; a rotating shaft 2d is also rotatably provided inside the housing 2, or more specifically, a connecting plate 2c for rotating shaft 2d may be fixedly provided inside the housing 2, and the rotating shaft 2d is rotatably connected to the connecting plate 2c through a bearing seat; the upper end of the rotating shaft 2d is fixedly provided with a second gear 2d1 meshing with the first gear 6a, and the lower end is fixedly provided with a third gear 2d2 meshing with the gear ring 1b1.

[0047] Please see Figure 5 Furthermore, each fan 4 on the connecting plate 2c is provided with a through slot 2c1 for the power cable to pass through.

[0048] In this way, the power cord of the fan 4 is constrained, which better prevents the power cord of the fan 4 from coming into contact with the gear ring 1b1, the first gear 6a, the second gear 2d1, or the third gear 2d2 when the fan 4, the housing 2, the motor 6, the slip ring 5 and other rotating parts are rotating together.

[0049] Please see Figure 4 In addition, to facilitate assembly on housing 2, housing 2 may include a lower housing portion 2a for connection with bearing 7 and an upper housing portion 2b for connection with power supply 6, connecting plate 2c, and multiple second rods 3. The upper housing portion 2b is detachably fixedly connected to the lower housing portion 2a.
