Description

Technical Field

[0001] This utility model relates to the field of sizing machine technology, and in particular to a selvage device for sizing machines. Background Technology

[0002] In the sizing process, the sized and dried yarn must be neatly wound onto a spool by a winding mechanism. However, due to the significant differences in physical properties between yarns of different materials (especially low-quality yarns with low strength, poor toughness, or uneven twist), traditional winding mechanisms cannot ensure that all yarns achieve the desired winding effect. Yarns with insufficient toughness or loose structure are prone to loosening, shifting, and piling during high-speed winding, failing to arrange themselves tightly and regularly on the spool, forming irregular yarn rolls that are messy, loose, or have local bulges. Such irregularly wound yarn rolls significantly increase the complexity and difficulty of subsequent unwinding, yarn separation, and warping processes, easily causing yarn breakage or tangling in later processing. Furthermore, they severely reduce the yarn capacity per spool, resulting in wasted space, significantly increasing the workload of manual sorting and rewinding, and reducing overall production efficiency and yarn manageability. Irregular winding can also easily conceal quality problems, such as excessive fuzz or weak yarn segments, and affect the smooth progress of subsequent weaving or dyeing processes. Therefore, it is necessary to add devices on both sides of the winding mechanism to wind yarns of poor quality.

[0003] Therefore, a selvage device for a sizing machine is proposed. Utility Model Content

[0004] One of the technical problems to be solved by this application is that devices that can wind yarn of poor quality need to be added to both sides of the winding mechanism.

[0005] To solve the above-mentioned technical problems, this application provides a sizing machine edge-adding device, including a bottom frame, a first support rod, a top frame, and a second support rod. A plurality of first support rods are provided on any side between the bottom frame and the top frame, and a plurality of second support rods are provided on the opposite side of the first support rods. A plurality of support rods are provided along the length of the second support rods. A cross frame is provided in front of the bottom frame and the top frame, and combing teeth are provided on the cross frame.

[0006] In some embodiments, support rod one is fixedly connected to the bottom frame and the top frame, support rod two is rotatably connected to the top frame at its top, and a rotation locking assembly is provided at the bottom of support rod two so that support rod two can be locked after rotation. The rotation locking assembly is provided on the bottom frame, and rollers are provided at the bottom of the bottom frame so that the bottom frame can move.

[0007] In some embodiments, a plurality of guide wires are provided on the support rod 1. The guide wires are fixed to the support rod 1 by screws. The guide wires also include a hole 1 at the rear end, a hole 2 at the front of the hole 1, a movable rod at the front of the hole 2, a pressing plate at the front of the movable rod, a connecting plate at the front of the pressing plate, and a hole 3 on the connecting plate.

[0008] In some embodiments, the rotary locking assembly includes a base disposed on the bottom frame, an outer sleeve disposed on the base, a guide rail disposed on the second support rod, a guide rod disposed within the guide rail, a connecting block fixedly connected to the guide rod, and a fixing block disposed between the second support rod and the outer sleeve, with a space formed between the fixing blocks and the connecting block located within the space.

[0009] In some embodiments, the fixing block is a block with a slope from low to high, a magnet is provided on the contact side between the fixing block and the connecting block, and a magnet is provided on the contact side between the connecting block and the fixing block, and the magnetic poles of the opposite sides of the magnet are opposite.

[0010] In some embodiments, the contact portion between the connecting block and the lower part of the inclined surface of the fixing block is rounded.

[0011] In some embodiments, the support rods are evenly distributed circumferentially along the two cross sections of the support rod.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. A yarn tension guide is installed on support rod one, allowing for flexible online adjustment of yarn tension by manually moving the lever. This eliminates the need for complex tools or machine downtime, effectively simplifying yarn tension control during production. Simultaneously, support rod two and its bottom rotating locking assembly allow for automatic yarn bobbin position switching and locking via a 90-degree manual rotation of support rod two after the inner yarn bobbin is fully wound. This utilizes the inclined guide rail and magnetic structure to quickly switch to the new empty yarn bobbin, significantly reducing the number of steps and waiting time required for bobbin replacement.

[0014] 2. The inclined fixing block in the rotary locking assembly works in conjunction with the smoothly rounded connecting block, and opposite-polarity magnets are placed on their contact surfaces, making yarn bobbin replacement smoother and less strenuous. With only a small rotational force, the connecting block easily slides into its higher position under the guidance of the inclined surface and locks itself in place naturally. Magnetic adsorption further enhances the stability of the lock, effectively preventing accidental rotation. This design significantly reduces the physical exertion and operational complexity of yarn bobbin replacement, while also avoiding the safety hazards of loosening or the need for tools that may occur with traditional locking methods, thus improving the safety and convenience of the operation.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly described below with reference to the accompanying drawings of the embodiments.

[0023] The embodiments described herein are clearly only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] Example 1, please refer to Figure 1-6 This utility model provides a technical solution: a sizing machine edge-adding device, including a bottom frame 100, a first support rod 200, a top frame 300, and a second support rod 400. A plurality of first support rods 200 are arranged on any side between the bottom frame 100 and the top frame 300, and a plurality of second support rods 400 are arranged on the opposite side of the first support rods 200. A plurality of support rods 401 are arranged along the length of the second support rods 400. A cross frame 500 is provided in front of the bottom frame 100 and the top frame 300, and comb teeth 501 are arranged on the cross frame 500.

[0025] Support rod 200 is fixedly connected to the bottom frame 100 and the top frame 300. The top of support rod 400 is rotatably connected to the top frame 300. A rotation locking assembly is provided at the bottom of support rod 400 so that support rod 400 can be locked after rotation. The rotation locking assembly is provided on the bottom frame 100. A roller 101 is provided at the bottom of the bottom frame 100 so that the bottom frame 100 can move.

[0026] Specifically, a rigid main frame of the device is formed by a base frame 100, a top frame 300, and a fixedly connected support rod 200, ensuring overall structural stability and the ability to withstand the load during yarn winding. Simultaneously, an independently designed support rod 400 is added as a core winding functional component. Its top is rotatably connected to the top frame 300 rather than fixedly, while its bottom engages with the base frame 100 via a specially designed rotary locking assembly. The purpose of this design is that the support rod 400 can rotate around its top axis. This allows operators to switch the positions of different yarn bobbin winding positions (i.e., the support rods 401) by rotating the support rod 400, while the main frame remains stationary, thus realizing the functional operation of the core working component.

[0027] A rotary locking assembly is installed at the bottom of support rod 2 400 and fixed to the base frame 100. Its design aims to ensure that support rod 2 400 can be reliably locked in the predetermined position after rotating 90 degrees to switch positions, preventing accidental shaking or rotation during subsequent winding. The core benefit of this design is the realization of quick, safe, and tool-free switching and locking of the yarn bobbin winding position. When a yarn bobbin is full, the operator only needs to manually rotate support rod 2 400 to the next empty yarn bobbin position, and the assembly automatically locks, requiring no additional tools or complex tightening steps. This significantly improves changeover efficiency and workflow, reducing non-productive downtime.

[0028] Casters 101 are installed at the bottom of the base frame 100. The direct purpose of this design is to enable the entire device to be easily moved. The significant benefit is a substantial increase in the device's practicality and adaptability. Operators can easily move the edge-adding device to the most suitable working position or storage area according to production needs, such as the location of the sizing machine winding mechanism, yarn type, and spatial layout. This flexibility meets the needs of different workstation configurations in the workshop and overcomes the drawbacks of rigid placement of fixed auxiliary devices.

[0029] A crossbeam 500 is installed at a key position in front of the bottom frame 100 and the top frame 300, and comb teeth 501 are mounted on it. Its main design purpose is to comb, gather, and guide the yarn before it is guided and wound onto the yarn bobbin on the support rod 400. The core benefit is that it effectively prevents the yarn from becoming tangled, crossed, or loose during the forward winding process. The comb teeth 501 act like a fine comb, organizing multiple or single strands of yarn, ensuring they are parallel and have relatively uniform tension as they reach the winding bobbin. This ensures that the yarn finally wound onto the spare bobbin is relatively neat and orderly, facilitating subsequent possible reprocessing or use.

[0030] Example 2, see Figures 1-6 The support rod 200 is provided with several guide wires 201. The guide wires 201 are fixed to the support rod 200 by screws 2017. The guide wires 201 also include a hole 2011 at the rear end, a hole 2012 at the front of the hole 2011, a movable rod 2013 at the front of the hole 2012, a pressing plate 2014 at the front of the movable rod 2013, a connecting plate 2015 at the front of the pressing plate 2014, and a hole 3016 on the connecting plate 2015.

[0031] Specifically, several independent yarn guides 201 are spaced apart on the support rod 200 and fixed to the support rod 200 with screws 2017. The purpose of this design is to modularize and distribute the key functional components for controlling yarn tension, enabling them to directly act on multiple independent yarns along the length of the support rod 200. The advantages are: each yarn guide 201 is responsible for the tension adjustment of its corresponding yarn, without interference, improving the device's ability and efficiency to handle multiple yarns simultaneously; the screw fixing method ensures that the yarn guides 201 remain firmly and stably during operation, preventing displacement due to vibration or operation, and guaranteeing the reliability of tension control.

[0032] The yarn guide 201 has a hole 2011 at its rear for initial yarn introduction, and a hole 2012 near its front. A movable rod 2013 is positioned in front of hole 2012. The core purpose of this design is to establish a predetermined tortuous path for the yarn and achieve online dynamic tension adjustment. The specific benefits are: the yarn first passes through hole 2011 to fix the introduction point, then passes through hole 2012 to form initial direction control and a micro-friction point; the movable rod 2013, as the core adjustment element, is designed to allow the operator to manually move it within a specific track on the yarn guide 201, such as pushing the yarn to tighten or loosen. This allows for intuitive and continuous adjustment of the yarn path's curvature, friction contact length, and force by simply moving the movable rod 2013, thereby achieving online, stepless, and instantaneous adjustment of yarn tension. The operation is extremely simple and flexible, making it particularly suitable for handling the tension requirements of yarns of different types or fluctuating quality.

[0033] One or more pairs of pressure plates 2014 are arranged in front of the movable rod 2013, and a connecting plate 2015 is arranged in front of it, with a hole 2016 on the connecting plate 2015. The purpose of this component is to provide final stable pressure and yarn exit direction positioning for the yarn after the initial guidance and tension adjustment. Its significant advantages are: the pressure plates 2014 provide a gentle and stable friction damping point for the yarn through elastic clamping or micro-pressure, which can help maintain the yarn tension and absorb some tension fluctuations, preventing the yarn from rebounding and loosening after adjustment; the yarn finally passes through the hole 2016 on the connecting plate 2015, which provides a clear and fixed yarn exit direction and end anchor point, ensuring that the yarn is transmitted forward to the subsequent device such as the comb tooth 501 with a stable and determined posture and tension, preventing end drift or sway from affecting the winding quality.

[0034] Example 3, see Figure 1-6 The rotary locking assembly includes a base 403 mounted on the base frame 100, an outer sleeve 402 mounted on the base 403, a guide rail 404 mounted on the second support rod 400, a guide rod 405 mounted inside the guide rail 404, a connecting block 406 fixedly connected to the guide rod 405, and a fixing block 407 mounted between the second support rod 400 and the outer sleeve 402. A space 408 is formed between the fixing blocks 407, and the connecting block 406 is located within the space 408.

[0035] The fixing block 407 is a block with slopes that rise from low to high. A magnet is installed on the contact side between the fixing block 407 and the connecting block 406, and a magnet is installed on the contact side between the connecting block 406 and the fixing block 407. The magnetic poles of the opposing surfaces of magnets 1 and 2 are opposite. The lower contact area between the slopes of the connecting block 406 and the fixing block 407 is rounded. Support rods 401 are evenly distributed circumferentially along the cross-section of support rod 400.

[0036] Specifically, several support rods 401 are installed on support rod 2 400, and they are evenly distributed along the diameter of the cross-section of support rod 2 400. The purpose of this design is to provide multiple symmetrically distributed winding stations for installing yarn bobbins. The core benefits are: each support rod 401 can carry a spare yarn bobbin, and the even distribution ensures that the yarn bobbins do not interfere with each other and that the rotation of support rod 2 400 is balanced; when one yarn bobbin is full, rotating support rod 2 400 ninety degrees can quickly switch to the next empty yarn bobbin, improving station switching efficiency and winding continuity, and maximizing the use of the device space.

[0037] The core rotary locking assembly includes a base 403 and an outer sleeve 402 fixed to the base frame 100, a guide rail 404 located on the second support rod 400, a guide rod 405 movable along the guide rail 404, a connecting block 406 fixed to the guide rod 405, and multiple inclined fixing blocks 407 disposed between the second support rod 400 and the outer sleeve 402. A space 408 is formed between the fixing blocks 407 to accommodate the connecting blocks 406, and magnets 1 and 2 that attract each other are respectively disposed on the contact surfaces of the fixing blocks 407 and the connecting blocks 406. Its design purpose is to achieve automatic position guidance and tool-free locking when the second support rod 400 rotates.

[0038] When the support rod 400 is manually rotated counterclockwise, the connecting block 406 begins to move along the inclined plane of the fixed block 407 from low to high. This inclined plane design, combined with the constraint of the guide rod 405 within the guide rail 404, allows the connecting block 406 to simultaneously undergo circular motion and upward linear movement along the axis of the support rod 400. The inclined plane guides the rotational motion into a partial lifting force with minimal effort. When the connecting block 406 reaches the highest point of the inclined plane, it automatically falls under the influence of gravity, precisely landing in the adjacent space 408. At this point, its position corresponds to a precise 90-degree rotation of the support rod 400, i.e., a workstation switch.

[0039] The connecting block 406 with magnet 2, which has fallen into place, and the adjacent fixing block 407 with magnet 1, generate an attractive force due to the different magnetic poles on their opposite surfaces. This magnetic force immediately and firmly attaches them to the side wall of the fixing block 407, forming a strong automatic locking mechanism. This design completely prevents the support rod 2 400 from accidentally rotating or loosening during winding, ensuring operational stability, and eliminating the need for any additional manual locking operations.

[0040] The contact area between the connecting block 406 and the fixed block 407 at the lower part of the inclined surface is rounded, which greatly reduces frictional resistance and the feeling of sticking at the moment of start-up, making the workstation switching operation more effortless and smooth, improving the operating feel and protecting the components.

[0041] The following is combined with Figures 1-6 The specific usage process is explained as follows:

[0042] The yarn is drawn from the winding mechanism of the sizing machine, passes through hole 2011 of the guide wire 201, passes through several rings in the middle of the guide wire 201, passes through hole 2012, then passes through the pressure plate 2014 in front of hole 2012, then passes through hole 3016 of the connecting plate 2015 in front of the pressure plate 2014, then passes through the comb teeth 501 of the cross frame 500 in front of the bottom frame 100 and the top frame 300, and finally is wound onto the yarn bobbin of the support rod 401 of the support rod 200. To adjust the yarn tension, simply move the movable rod 2013 within the arc track on the guide wire 201 to push the yarn to tighten or loosen.

[0043] Once the internal yarn bobbin is fully wound, the worker grasps the support rod 401 on the second support rod 400 and rotates the second support rod 400 counterclockwise. At this time, the connecting block 406 at the bottom of the second support rod 400 will rotate counterclockwise along the inclined surface of the fixed block 407. Simultaneously, since the connecting block 406 is set on the guide rail 404 via the guide rod 405, the guide rod 405 moves upward along the guide rail 404 during the rotation, consistent with the process of the connecting block 406 moving from low to high along the inclined surface of the fixed block 407. During this process, the connecting block 406 performs both rotational and upward linear motion. When it reaches the highest point of the fixed block 407, the connecting block 406 rotates 90 degrees and falls into another empty space 408 under the action of gravity. At this time, since the magnetic poles of the first magnet of the fixed block 407 and the second magnet of the connecting block 406 are opposite, the connecting block 406 and the fixed block 407 are attracted together, thus achieving a locked state and preventing the connecting block 406 from continuing to rotate. At this point, the bobbin on the unwound support rod 401 rotates inward to continue winding the yarn. To replace the bobbin on the next support rod 401 that is winding yarn, the operator simply needs to continue rotating the support rod 400 by ninety degrees, and the process is the same as described above.
