Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology and relates to a spindle wing structure for a roving frame. Background Technology

[0002] A roving frame that winds roving onto a bobbin is equipped with a spindle. The function of the spindle is to be mounted on a shaft. Under the action of centrifugal force, the spindle rotates to wind the roving onto the shaft. However, due to the yarn guide tube on one side and the addition of a pressure arm and pressure blade, the high-speed rotating spindle will cause an imbalance in the weight distribution between the spindle legs, making it impossible to rotate at high speed. Therefore, we propose a roving spindle. Utility Model Content

Detailed Implementation

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] like Figure 1-3 As shown, this utility model is a spindle wing structure for a roving frame, including a hub 11. One end of the hub 11 extends downward to form a first spindle wing leg 21 and a second spindle wing leg 3. The end of the second spindle wing leg 3 is provided with a cavity, and the end is connected to a third spindle wing leg 36. A counterweight assembly is provided between the end cavity and the third spindle wing leg 36 to balance the counterweight between the wing legs.

[0025] Preferably, the counterweight assembly includes an inner ring 31 disposed in the cavity, the lower end of the inner ring 31 being connected to the third spindle leg 36 via a connecting plate 35; the connecting plate 35 has a semi-circular arc structure; a spring 32 is disposed inside the inner ring 31, the upper end of the spring 32 being connected to the second spindle leg 3, and a baffle 33 is disposed at the lower end of the spring 32.

[0026] Preferably, the counterweight assembly further includes a rotating block 4, which has a circular hole 42 and a stud 41 at its upper end.

[0027] The inner ring 31 has an internal thread 34 at its lower part, which is screwed to the stud 41 so that the stud 41 and the inner ring 31 can be integrated to ensure that the micro-weight 5 will not move downward.

[0028] A micro-weight 5 is provided between the stud 41 and the baffle 33. The micro-weight 5 is provided to ensure the balance of the weight between the wing legs.

[0029] A retaining ring 6 is slidably provided between the inner ring 31 and the second spindle leg 3. The lower end of the retaining ring 6 contacts the third spindle leg 36 to form a closed state between the second spindle leg 3 and the third spindle leg 36, preventing external dust from entering the second spindle leg 3.

[0030] By setting micro-weights 5, they can be installed or removed as needed, thereby achieving dynamic balance adjustment with the second spindle wing leg 3.

[0031] The stud 41 and spring 32 are used to ensure the stable placement of the micro-weight 5, thereby further adjusting the dynamic balance of the wing legs.

[0032] First, push the retaining ring 6 upwards, then place the micro-weight 5 on the upper end of the stud 41. Rotate the stud 41 so that the stud 41 and the internal thread 34 form a threaded connection, thus fixing the position of the stud 41. During the process of the stud 41 and the internal thread 34 being screwed together, the micro-weight 5 moves upwards, compressing the spring 32. Conversely, the spring 32 always exerts a reaction force on the micro-weight 5, thereby ensuring the stability of the micro-weight 5.

[0033] In this embodiment, a palm presser arm 22 is also connected to one end of the first spindle leg 21, and a palm presser blade 23 is also connected to one end of the palm presser arm 22; preferably, a spindle main shaft 12 is also provided on the hub 11, and the spindle main shaft 12 extends downward to the center position of the first spindle leg 21 and the second spindle leg 3.

[0034] A spindle portion 1 is provided on the other end of the hub portion 11.

[0035] A yarn guide tube 2 is inserted inside the spindle part 1 and extends into the first spindle wing leg 21, and the curvature of the yarn guide tube 2 is consistent with the curvature of the second spindle wing leg 3.

[0036] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
