Description

Technical Field

[0001] This utility model relates to the field of yarn twisting machines, and in particular to a yarn unwinding and anti-entanglement device for yarn twisting machines. Background Technology

[0002] In the spinning process of the textile industry, the key step is to simultaneously unwind multiple single yarns from their respective yarn feeders and combine them into a single strand. During this process, as the yarn is axially unwound from the high-speed rotating yarn feeders, it forms a dynamically rotating "air ring" due to centrifugal force. The size and shape of this air ring are crucial for the smooth unwinding of the yarn, reducing tension fluctuations, and preventing yarn breakage.

[0003] However, existing spinning machines generally use a fixed spindle pitch (i.e., the installation distance between the centers of two adjacent yarn feeders). This fixed spindle pitch design has a significant drawback: it cannot dynamically adjust the distance between adjacent yarn feeders according to the actual characteristics of the unwound yarn and process requirements. As a result, it cannot provide the optimal air pocket space required by different yarns, which is one of the root causes of mutual interference between the unwound air pockets of adjacent yarns, tangling and knotting, increased breakage rate, decreased production efficiency, and damaged product quality. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a yarn unwinding and anti-entanglement device for a doubling machine to solve the technical problems in the prior art.

[0005] To achieve the above objectives, this utility model provides a yarn unwinding and anti-entanglement device for a doubling machine, comprising a chassis and a column vertically fixed on the chassis; At least two yarn feed tubes, each yarn feed tube is installed on the chassis via an independent connecting rod; Adjustment component one for adjusting the radial position of the yarn feed bobbin, the adjustment component one comprising: The adjusting disc, which is rotatably mounted on the column, has multiple adjusting grooves evenly distributed along the circumference on its surface. A toothed ring fixed to the outer ring of the adjusting disc; A gear that meshes with a gear ring, the gear being fixedly connected to a rotating shaft, and the bottom of the rotating shaft being rotatably mounted on a chassis; One end of the connecting rod is slidably connected to the corresponding adjustment groove.

[0006] Preferably, there are multiple yarn supply cylinders, which are equidistantly distributed along the circumference of the chassis.

[0007] Preferably, the chassis surface has radial grooves matching the number of connecting rods, and the connecting rods are slidably installed in the corresponding grooves.

[0008] Preferably, the number of adjustment grooves is the same as the number of yarn feeding cylinders, and each adjustment groove is arranged at equal intervals along the circumference of the adjustment disc.

[0009] Preferably, one end of the connecting rod that connects to the adjusting groove is fixed with a columnar guide pin, and the upper end of the guide pin extends into the adjusting groove and slides therewith.

[0010] Preferably, the extension direction of the adjustment groove gradually approaches the axis of the adjustment disc from one end to the other, forming an inclined groove structure.

[0011] Preferably, the device further includes: a yarn guide plate disposed on the column, the yarn guide plate having yarn guide holes penetrating its upper and lower end faces, and a height adjustment component two disposed between the yarn guide plate and the column, the adjustment component two including: Multiple limiting holes are arranged along the axial direction of the column; The sliding limit pin through the yarn guide disc can be inserted into any limit hole at its front end. A retaining ring fixed in the middle of the limiting pin; A spring is fitted onto a limiting pin, with its two ends abutting against the inner wall of the yarn guide disc and a fixing ring, respectively.

[0012] Preferably, the upper and lower inlet end faces of the yarn disc hole are both arc transition surfaces.

[0013] The beneficial effects of this utility model are as follows: The yarn unwinding and anti-entanglement device of the doubling machine of this utility model, through the setting of components such as yarn supply cylinders, adjusting plate and adjusting groove, realizes the equal-distance adjustment of multiple equally distributed yarn supply cylinders, and makes multiple yarns relatively close and relatively far apart. By increasing or decreasing the yarn spacing in this way, it is possible to make flexible adjustments according to process requirements, further improve the stability of yarn unwinding, and avoid the problem of yarn entanglement caused by two adjacent air rings being too close. The use of components such as columns, limiting holes, and limiting pins allows for easy adjustment of the yarn guide plate height according to the size of the air ring. This effectively compresses the diameter of the air ring, preventing yarn tangling and thus optimizing the air ring shape to eliminate tension fluctuations. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0018] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0019] The first aspect of this utility model proposes a yarn unwinding and anti-entanglement device for a doubling machine, such as... Figure 1-4 As shown, it includes a chassis 1 and a column 2 vertically fixed to the chassis 1; At least two yarn supply cylinders 3, each yarn supply cylinder 3 is installed on the chassis 1 via an independent connecting rod 4; Adjustment component one is used to adjust the radial position of the yarn feed cylinder 3. Adjustment component one includes: The adjusting disc 5, which is rotatably mounted on the column 2, has multiple adjusting grooves 6 evenly distributed along the circumference on its surface. It should be added that the inner ring of the adjusting disc 5 is provided with a bearing, and the inner ring of the bearing is fixedly connected to the surface of the column 2, while the outer ring of the bearing is fixedly connected to the inner wall of the adjusting disc 5, thereby improving the stability of the rotation of the adjusting disc 5. Gear ring 7 fixed to the outer ring of the adjusting disc 5; Gear 8 meshes with gear ring 7, gear 8 is fixedly connected to rotating shaft 9, and the bottom of rotating shaft 9 is rotatably mounted on chassis 1; One end of the connecting rod 4 is slidably connected to the corresponding adjusting groove 6.

[0020] In the unwinding of yarn on a doubling machine, different yarns (cotton / chemical fiber / blended), different counts (coarse / fine), and different unwinding speeds require different air ring spaces. Therefore, the distance between two adjacent yarn feed cylinders 3 needs to be adjusted accordingly to avoid yarn entanglement caused by the air rings being too close. By rotating the shaft 9 on the gear 8, the gear 8 meshes with the toothed ring 7 on the outer wall of the adjusting disc 5, causing the adjusting disc 5 to rotate. At this time, the position of the adjusting groove 6 on the surface of the adjusting disc 5 changes, thereby driving the connecting rod 4, which is slidably installed in the adjusting groove 6, to move along the guide of the slide groove 101. This allows multiple equally spaced yarn feed cylinders 3 to drive the yarns mounted on the surface to adjust at equal intervals, moving the yarns relatively closer or further apart. This method increases or decreases the yarn spacing to allow for flexible adjustments according to process requirements, further improving the stability of yarn unwinding.

[0021] In this embodiment, multiple yarn supply cylinders 3 are provided, and the multiple yarn supply cylinders 3 are equidistantly distributed along the circumference of the chassis 1. The equidistant distribution of multiple yarn supply cylinders 3 enhances the stability of the air ring, reduces air ring collision, and lowers the risk of entanglement.

[0022] In this embodiment, the chassis 1 has radial grooves 101 on its surface that match the number of connecting rods 4, and the connecting rods 4 are slidably installed in the corresponding grooves 101. The slidable installation of the connecting rods 4 in the corresponding grooves 101 further improves the stability of their movement.

[0023] In this embodiment, the number of adjusting grooves 6 is the same as the number of yarn supply cylinders 3, and each adjusting groove 6 is arranged at equal intervals along the circumference of the adjusting disc 5. It should be noted that several adjusting grooves 6 correspond one-to-one with multiple yarn supply cylinders 3 to ensure that one adjusting groove 6 corresponds to one yarn supply cylinder 3.

[0024] In this embodiment: a columnar guide pin is fixed to one end of the connecting rod 4 that connects to the adjusting groove 6. The upper end of the guide pin extends into the adjusting groove 6 and slides therewith. When the guide pin slides in the adjusting groove 6, the friction between the two is reduced.

[0025] In this embodiment, the adjusting groove 6 extends from one end to the other, gradually approaching the axis of the adjusting disc 5, forming an inclined groove structure. When the adjusting disc 5 rotates clockwise, the adjusting groove 6 drives the connecting rod 4 to move away from the axis of the adjusting disc 5. When the adjusting disc 5 rotates counterclockwise, the adjusting groove 6 drives the connecting rod 4 to move closer to the axis of the next adjusting disc 5, thereby achieving equidistant adjustment of the distance between multiple yarn supply cylinders 3.

[0026] In this embodiment, the device further includes: a yarn guide plate 10 disposed on the column 2, the yarn guide plate 10 having yarn guide holes 11 penetrating its upper and lower end faces, and a height adjustment component two being provided between the yarn guide plate 10 and the column 2, the adjustment component two including: Multiple limiting holes 12 are arranged along the axis of column 2; The limiting pin 13 slides through the yarn guide disc 10, and its front end can be inserted into any limiting hole 12; A retaining ring 14 is fixed to the middle of the limiting pin 13; A spring 15 is fitted onto the limiting pin 13, with its two ends abutting against the inner wall of the yarn guide plate 10 and the fixing ring 14, respectively.

[0027] Since the size of the spatial movement trajectory of the yarn during unwinding directly affects the tension stability, and the diameter of the air ring is determined by both the height of the yarn guide plate 10 and the yarn diameter, adjusting the height of the yarn guide plate 10 according to the size of the air ring can effectively compress the diameter of the air ring and avoid winding problems. When adjusting the height of the yarn guide plate 10, the limiting pin 13 is pulled so that one end moves out of the corresponding limiting hole 12. At this time, the spring 15 is compressed. By raising and lowering the yarn guide plate 10, after the yarn guide plate 10 is raised or lowered to the required height, the limiting pin 13 is released. At this time, the spring 15 elastically returns to its original position and pushes the fixing ring 14 on the limiting pin 13 so that one end of the limiting pin 13 is inserted into the corresponding limiting hole 12, thereby completing the height adjustment of the yarn guide plate 10 and thus better optimizing the shape of the air ring and eliminating tension fluctuation problems.

[0028] In this embodiment, both the upper and lower inlet faces of the yarn tray hole 11 are rounded transition surfaces. By setting the rounded transition surfaces, compared with the angular vertical surfaces, yarn friction damage can be reduced.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
