Technical Field
[0001] This utility model relates to the field of yarn frame accessories, specifically a yarn frame anti-tipping and stabilizing mechanism for a large circular knitting machine. Background Technology
[0002] The main function of a yarn feeder is to support and transport yarn, ensuring the continuity and stability of the yarn during production. Its structure consists of a support frame, a yarn spool mounting device, and a yarn guide device. The support frame is typically made of sturdy metal and designed with multiple arms or layers to support multiple yarn spools, meeting the need for simultaneous supply of multiple yarns. The yarn spool clamping device must be both secure and easy to replace, ensuring smooth and tangle-free yarn rotation. The yarn guide device guides the yarn smoothly to the spinning or weaving equipment. Modern equipment is also equipped with adjustable guide wheels or guide tubes to reduce [unspecified issues]. The possibility of friction and breakage; with the increase in production efficiency and the demand for multi-threaded supply, yarn racks are prone to instability in actual use, especially when multiple yarn drums are unloaded at the same time. This is because yarn racks are mostly multi-arm or multi-layered supports used to support multiple yarn drums. When multiple threads are unloaded at the same time, the tension and pull of the yarn will change constantly, and some yarns may be subjected to greater tension, which will cause the overall balance of the yarn rack to be disrupted. Furthermore, the installation environment and foundation conditions of the yarn rack will also affect its stability. For example, uneven ground or an unstable foundation may cause the yarn rack to shift or shake. Utility Model Content
[0003] The purpose of this utility model is to provide a yarn frame anti-tipping stabilizing mechanism for a large circular knitting machine. The bottom frame spans the lower end beam of the yarn frame, so that the left and right loop-shaped support plates are located on the left and right outer walls of the yarn frame. Stabilizing rods are installed at the top of the left and right loop-shaped support plates. By controlling the switch and the linkage assembly, the left and right loop-shaped support plates are brought closer to each other until they abut against the left and right outer walls of the yarn frame, so that the yarn frame can be stably supported and prevented from tipping, thereby solving the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a yarn frame anti-tipping stabilizing mechanism for a large circular knitting machine, comprising a base frame, an upper frame fixedly installed at the top of the base frame, and a left loop support plate and a right loop support plate slidably installed at the left and right positions of the base frame and the upper frame, respectively. The top of each of the left and right loop support plates is threaded with several equally spaced stabilizing rods. The top of the base frame is equipped with a connecting rod tension assembly for causing the left and right loop support plates to move linearly towards each other. A control switch is installed on one outer wall of the base frame, and the output end of the control switch is electrically connected to the input end of the connecting rod tension assembly.
[0005] Preferably, I-shaped columns are welded and installed at both sides of the top edge of the bottom frame, and the top of the I-shaped columns is welded to the bottom of the top frame.
[0006] Preferably, the top ends of the left and right spiral support plates are provided with a plurality of downwardly extending internal threaded grooves, and the lower outer circumferential surface of the stabilizer bar is provided with an external threaded groove.
[0007] Preferably, a U-shaped frame is fixed on the outer wall of the left and right circular support plates that are close to each other, and two sliding sleeves are installed on the top of the U-shaped frame.
[0008] Preferably, two circular guide rails are installed at the front and rear positions of the top of the bottom frame, and the sliding sleeve and the circular guide rails are in sliding engagement.
[0009] Preferably, the connecting rod assembly includes a geared motor mounted on the top of the bottom frame, a rocker arm mounted on the upper end of the geared motor drive shaft, and connecting rods hinged to both ends of the rocker arm. One end of one connecting rod is hinged to a U-shaped frame on the outer wall of the left loop support plate, and one end of the other connecting rod is hinged to a U-shaped frame on the outer wall of the right loop support plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This anti-tipping stabilizing mechanism for a yarn frame on a circular knitting machine allows the bottom frame to span the lower crossbeam of the yarn frame, positioning the left and right loop-shaped support plates at the left and right outer walls of the yarn frame. Stabilizing rods are installed at the top of the left and right loop-shaped support plates. By controlling the switch and connecting rod assembly, the left and right loop-shaped support plates are brought closer together until they abut against the left and right outer walls of the yarn frame, thus providing stable support and preventing tilting. This ensures the overall rigidity of the yarn frame and provides a reliable foundation for subsequent stable support and continuous yarn feeding. The installation of stabilizing rods at the top of the left and right loop-shaped support plates creates an adjustable support structure. The system, through control switches and linkage assemblies, allows adjustment of the proximity of the left and right loop support plates according to actual needs. As the left and right loop support plates gradually approach the left and right outer walls of the yarn frame, they form a tight wrapping and support structure, effectively limiting the lateral swaying and tilting of the yarn frame and enhancing overall stability. Secondly, the left and right loop support plates and the outer walls of the yarn frame form a multi-point support system, effectively dispersing the lateral pressure generated by the yarn drum, reducing the risk of deformation or collapse caused by excessive local stress. Furthermore, operators can adjust the proximity of the left and right loop support plates to adapt to different stress states during different process stages or when using different types of yarn. This adjustability greatly improves the adaptability and ease of use of the yarn frame. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0018] Please see Figure 1-5 The present invention provides an embodiment of a yarn frame anti-tipping stabilizing mechanism for a large circular knitting machine, comprising a base frame 1, an upper frame 3 fixedly installed at the top of the base frame 1, and a left loop support plate 5 and a right loop support plate 6 slidably installed at the left and right positions of the base frame 1 and the upper frame 3, respectively. The top of the left loop support plate 5 and the right loop support plate 6 are threaded with a plurality of equally spaced stabilizing rods 7. The top of the base frame 1 is equipped with a connecting rod pull assembly 4 for causing the left loop support plate 5 and the right loop support plate 6 to move linearly toward each other. A control switch 8 is installed on one side of the outer wall of the base frame 1, and the output end of the control switch 8 is electrically connected to the input end of the connecting rod pull assembly 4.
[0019] I-shaped columns 2 are welded and installed at both sides of the top of the bottom frame 1, and the top of the I-shaped columns 2 is welded to the bottom of the top frame 3.
[0020] The top of the left loop support plate 5 and the right loop support plate 6 are provided with several downward-extending internal thread grooves, and the lower end of the stabilizer bar 7 is provided with an external thread groove, so that the lower end of the stabilizer bar 7 is installed at the top of the left loop support plate 5 and the right loop support plate 6 in a threaded manner, thereby improving the anti-tilting area of the mechanism in the vertical direction by using the stabilizer bar 7.
[0021] U-shaped frames 9 are fixed on the outer walls of the left and right circular support plates 5 and 6 respectively. Two sliding sleeves 10 are installed at the top of the U-shaped frame 9. Two circular guide rails are installed at the front and rear positions of the top of the bottom frame 1. The sliding sleeves 10 and the circular guide rails slide together. During the sliding of the left and right circular support plates 5 and 6, the left and right circular support plates 5 and 6 can slide together through the U-shaped frame 9 and the sliding sleeves 10 at the top of the U-shaped frame 9 and the circular guide rails to improve the sliding stability of the left and right circular support plates 5 and 6 in the horizontal direction.
[0022] The linkage assembly 4 includes a geared motor 401 mounted on the top of the bottom frame 1, a rocker arm 402 mounted on the upper end of the drive shaft of the geared motor 401, and connecting rods 403 hinged to both ends of the rocker arm 402. One end of one connecting rod 403 is hinged to a U-shaped frame 9 on the outer wall of the left loop support plate 5, and one end of the other connecting rod 403 is hinged to a U-shaped frame 9 on the outer wall of the right loop support plate 6. When the linkage assembly 4 is working, the geared motor 401 is controlled by the control switch 8 to work, and the geared motor 401 drives the rocker arm 402 to rotate. During the rotation of the rocker arm 402, the connecting rods 403 at the end of the rocker arm 402 drive the left loop support plate 5 and the right loop support plate 6 to move towards the central axis of the drive shaft of the geared motor 401, that is, the left loop support plate 5 and the right loop support plate 6 move closer to each other or further away, so as to make the left loop support plate 5 and the right loop support plate 6 support the side wall of the yarn frame.
[0023] In this embodiment, the operator first positions the yarn frame to ensure its foundation is stable, preventing displacement or tilting due to uneven ground during subsequent operations. Then, the bottom frame 1 and top frame 3 are laid across the bottom beam of the yarn frame, positioning the left loop support plate 5 and right loop support plate 6 on the left and right outer walls of the yarn frame. The operator then removes several stabilizing rods 7, threading the lower ends of the stabilizing rods 7 onto the tops of the left loop support plate 5 and right loop support plate 6, thereby increasing the anti-tilting area of the mechanism in the vertical direction. After the stabilizing rods 7 are assembled with the left loop support plate 5 and right loop support plate 6, the operator activates the connecting rod pull assembly 4 via the control switch 8, which in turn engages the left loop support plate 5 and right loop support plate 6. As the yarn frame gradually approaches its left and right outer walls, the operator should closely observe the movement of the left and right loop support plates 5 and 6 during operation to ensure they move smoothly without shifting or jamming. When the left and right loop support plates 5 and 6 are firmly against the outer wall of the yarn frame, the operator should check the stability rod 7 again to ensure the tight connection of the entire mechanism. After the left and right loop support plates 5 and 6 are in place against the outer wall of the yarn frame, a comprehensive safety inspection should be conducted to ensure that all connecting parts are firmly fixed and that the left and right loop support plates 5 and 6 are tightly fitted to the yarn frame without loosening or shifting. A slight shaking test can then be performed to observe the stability of the yarn frame and ensure that it will not tip over or shake during normal use.
