Description

Integrated open slot looping device

Technical Field

The invention relates to the field of spinning cake processing, in particular to an integrated 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 to automatic conversion, whether can be based on the defects in the prior art, the improved integrated open slot looping device is provided, the manual knotting is simulated aiming at the silk thread looping process, the integrated open slot structure is provided, the looping and the looping back of the silk thread are realized by matching the thread pushing mechanism, the looping requirement can be met, the completeness of the loop returning process coil can be ensured, and the technical problem to be solved urgently by technical personnel in the field is formed.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 integrated open slot looping device of the first embodiment is used for a knotter, the knotter knottes silk threads on a cake, and the integrated open slot looping device includes: the device comprises a rack, a driving mechanism 1, a transmission mechanism 2, a wire pushing mechanism 3 and an open slot mechanism 4. The driving mechanism 1 is preferably a motor, but is not limited thereto, and other devices may be employed. The wire pushing mechanism 3 is preferably a cylinder, but is not limited thereto, and other devices may be employed. The open groove mechanism 4 is preferably in the form of a hollow cylinder, but is not limited thereto. The driving mechanism 1 is arranged on the rack, the wire pushing mechanism 3 is arranged on the rack, the transmission mechanism 2 is arranged on the driving mechanism 1, and the open slot mechanism 4 is arranged on the transmission mechanism 2. The transmission mechanism 21 is used for connecting the driving mechanism and the open slot mechanism 4, and the driving mechanism 1 drives the open slot mechanism 4 to rotate in the action process of the integrated 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 3 picks up the thread above the hollow cylindrical open slot mechanism 4, and fixes the thread clamping slot 41 of the thread aligned with the hollow cylindrical open slot mechanism 4. The slot-clamping slot 41 is groove-shaped and is wholly lower than the upper surface of the hollow cylindrical open slot mechanism 4. After the position of the wire pushing mechanism 3 is accurately positioned, the silk threads are fed into the wire clamping groove 41, and the silk threads are fixed in the groove, so that the silk threads cannot be taken out and slide on the surface of the rolled spinning cake in the subsequent rotating and looping process.

After the wire is looped, as shown in fig. 3, the loop on the open slot mechanism 4 in the hollow cylindrical shape needs to be taken down to complete the final knotting. In order to facilitate the wire pushing mechanism 3 to push out the coil, an opening with a certain width is reserved on the side edge of the hollow cylindrical open slot mechanism 4 along the wire pushing direction, the wire pushing mechanism 3 enters the hollow cylindrical open slot mechanism 4 along the opening, a certain force is given to push the silk thread out of the wire clamping slot 41, and then the final tensioning and knot forming work is completed.

As shown in fig. 4, the thread pushing mechanism 3 provides a certain pushing force to the thread which completes the rotary looping operation, so as to drive the thread to slide out from the groove-shaped thread clamping groove 41, and meanwhile, in order to reduce the friction force of the surface of the hollow cylindrical open slot mechanism 4 to the thread, an inclined plane with a certain taper is arranged at the tail of the hollow cylindrical open slot mechanism 4, namely, an auxiliary loop withdrawing mechanism 42 is arranged, the inclined plane is designed to be hollow, so that the possibility that the thread breaks due to the friction force applied to the surface of the thread is further reduced.

As described above, according to the integral type open slot looping device of the first embodiment, compared with the prior art, only one integral device is needed to realize the looping work of the silk thread, on the premise of ensuring smooth looping, the work flow of the knotting machine is simplified, the production speed of the knotting machine is improved to a great extent, the lightweight effect can be achieved, the traditional manual knotting looping work is replaced, the influence factor of the silk thread looping is fully considered, the manual knotting process steps are referred, the feasibility of knotting looping is improved, the problems of low efficiency and many uncontrollable factors of manual knotting are solved, and the production efficiency of a factory is improved. Compared with a nipper type knotter, the yarn clamping design can effectively solve the problem that the yarns easily slide off in the looping process, thereby reducing the influence of external factors on the whole looping process and improving the stability and reliability of looping. Meanwhile, the phenomenon that the tension borne by the silk thread exceeds the maximum breaking strength due to the movement precision error of the mechanism to cause the sudden breakage of the coil is prevented, so that the coil withdrawing auxiliary mechanism is adopted to ensure that the looping work can be finished and the requirement of the coil withdrawing can be met. This device improves on this basis according to the problem that artifical lopping exists, makes the device have the function such as quick that people's function can reach, accuracy, dexterity, has improved the efficiency of lopping, realizes the automated processing to the spinning cake, reduces the human cost, improves production efficiency and automated production, realizes the intelligent processing to the spinning cake.
