Description

Split type open slot looping device

Technical Field

The invention relates to the field of spinning cake processing, in particular to a split type open slot looping device.

Background

After the package silk is stripped, the package silk needs to be sent to a warehouse for storage so as to be packaged or sent to the next procedure for continuous processing. If the filament ends of the rolled spinning cakes are not fixed, the filament ends can be scattered in the transportation process. The scattered yarn heads are easy to wind on other objects, and the wound yarn heads are messy, so that the influence of inconvenient operation on the next procedure is caused, and knotting can be an essential part in the spinning process. In the textile field, the processes of heading, stripping, knotting and the like of spinning cakes are generally performed manually at present. However, there are many inconveniences, for example, some filament vehicles are as high as one meter and seven just by the head beam, and a shorter operator is very inconvenient to perform the operations of stripping filament from cake, knotting and inspecting broken filament at the uppermost layer. The precision of manual operation by an operator varies from person to person and very high precision cannot be guaranteed. In particular, when an elderly operator is not sufficient in physical strength, the accuracy further decreases.

The air splicer is provided in the current textile industry, has wider application range, and is suitable for splicing yarns of different raw materials, yarn numbers and different twisting coefficients, such as cotton, wool, silk, filament polyester, acrylic fiber and the like. The air splicer is applicable not only to a bobbin winder but also to a process related to a knot such as a doubling machine, a twisting machine, a reeling machine, a skein machine, a warping machine, and the like. However, the air splicer has a problem in that the splice slips due to excessively low twisting pressure, excessively long twist section, or insufficient untwisting.

Besides, the self-tightening knotter is suitable for cotton and cotton chemical fibers with the density of 18-58tex, and the tail length is 4-7 mm. The self-tightening knot is composed of two incomplete knots, the ends are opposite, the knot roots are opposite, and the two incomplete knots are combined into a whole when the self-tightening knot is tightened. And the yarn is not easy to be separated when the yarn is pulled and tightened, is widely applied to textile factories, and is particularly suitable for smoother polyester spinning or polyester-cotton blended yarns. However, the self-clinching knotter has a problem that it is apt to be entangled by friction with adjacent yarns when weaving a high-density fabric, so that a shed is unclear, and the self-clinching is rubbed by dents when beating up, so that a broken end is sometimes generated.

The two knotters are based on knotting and looping of two silk threads, but at present, based on knotting of a single silk thread, the knotters comprise a kelp knotter and C-shaped and D-shaped buckle type square bale knotters which form a phi ring by rotating a clamp mouth for a circle. To sum up, in the textile industry at present, the manual knotting method that the mill adopted to single silk also consequently also adopts artificial mode at the looping of knoing in-process, and intensity of labour is big, low in labor efficiency, and the quality is difficult to guarantee, and the knot of beating moreover has the uncertainty, in follow-up weighing, the outward appearance detects the link, causes very easily that not only does not lead to the fact certain influence to the outward appearance detection that becomes flexible knot scatters, and because the scattering of knot can lead to the silk thread constantly to slide from the spinning cake and lead to the silk thread to appear on the tray of transportation spinning cake and various places moreover.

Therefore, the single silk thread knotting is urgently needed from manual work to automatic transformation, whether can be based on the deficiency among the prior art, a split type open slot looping device of modified is provided, the manual knotting is simulated to the silk thread looping process, a split type open slot structure is provided, the cooperation pushes away the mechanism simultaneously and realizes the looping and the returning of silk thread, the looping requirement both can be satisfied, the integrality of the loop process coil can be guaranteed to return, become the technical problem that technical personnel in the field need to solve urgently.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, the split open groove looping device of the first embodiment is used for a knotter, the knotter knottes silk threads on a cake, and the split open groove looping device includes: the device comprises a frame, a driving mechanism 1, a transmission mechanism 2, a wire pushing mechanism (not shown), a guide mechanism 3, a composite coiling mechanism and a wire fixing mechanism 6. The driving mechanism 1 is preferably a motor, but is not limited thereto, and other devices may be employed. The wire pushing mechanism is preferably a cylinder, but is not limited thereto, and other devices may be employed. The driving mechanism 1 is arranged on the frame, the transmission mechanism 2 is arranged on the driving mechanism 1, the guide mechanism 3 is arranged on the transmission mechanism 2, the composite looping mechanism is arranged on the guide mechanism 3 and comprises two

open slots

4 and 5, and the thread fixing mechanism 6 is arranged on the composite looping mechanism. In fig. 1, the a-side open groove of the composite looping mechanism is, for example, a C-shaped open groove, and the B-side open groove is, for example, an F-shaped open groove. The driving mechanism 1 drives the composite looping mechanism and the thread fixing mechanism 6 to rotate in the action process of the split open slot looping device. Specifically, the driving mechanism 1 drives the lower component to complete the rotary looping work, and the transmission of the force of the driving source and the actuating element is realized by using the transmission mechanism 2.

As shown in fig. 2, the thread pushing mechanism enables the silk thread to be fed into the A-side open groove, meanwhile, the B-side open groove descends to form a double-side closed inclined shape (a closed ring) with the A-side open groove, the silk thread can be clamped in the double-side closed inclined shape, meanwhile, the silk thread is prevented from slipping, the silk thread is in a state before the silk thread is manually knotted and rotates at the moment, the silk thread is in a square open shape at the A, B-side open groove, a follow-up thread inlet space is reserved, the A, B-side open groove is designed to be in a hollow-out mode, follow-up process wire inlet is facilitated, a loop is withdrawn, and the weight of the whole device is reduced.

As shown in fig. 3 and 4, after the open slot at the side A, B of the filament is divergent (see fig. 4), the filament is easily broken during rotation due to a small included angle between the divergent sides and the vertical direction, and the filament clamped in the open slot at the side A, B is deviated in position and cannot be looped. The thread fixing mechanism 6 is utilized to press down the threads on two sides of the dispersed thread, the included angle between the threads and the vertical direction is increased, so that the threads form a square opening shape, and the thread winding operation is completed under the driving of the driving mechanism 1.
