Description

Technical Field

[0002] In acrylic yarn fabrics, commonly known as artificial wool, the fabrics have a soft and fluffy feel similar to wool fabrics, bright colors, and good warmth retention, and are deeply loved by consumers. In the manufacturing process of acrylic yarn fabrics, a roving frame is required for operation. After retrieval, it is found that in the existing public technology, the publication number is: CN116971065A, an efficient flyer roving frame, including a bracket, a creel is arranged at the rear side of the bracket, a drafting device is arranged at the top of the bracket, an upper creel is arranged at the front side of the top of the bracket, flyer spindles are arranged on the upper creel, a lower creel is arranged below the upper creel, and a bobbin corresponding to the flyer spindles is arranged on the lower creel; a roving automatic cutting device is arranged at the end of the outlet wing rod of the flyer spindle. The pressure roller group of the automatic cutting device will gradually move backward as the thickness of the roving wound on the bobbin increases. After moving backward a certain distance, it will quickly jump backward. After jumping backward, the cutters on both sides of the pressure roller group will close to cut the roving in front of the pressure roller group, resulting in a relatively long section of roving remaining in front of the pressure roller group after cutting. After the full-wound bobbin is removed, the pressure roller group will automatically push the roving to the farthest position (to achieve reset), push the end of the roving to near the empty bobbin, and realize the automatic winding of the subsequent bobbin, achieving automatic cutting and the lap operation of the roving head before winding.

[0003] To sum up: The roving frame set in the above case does not have the function of detecting broken yarns, thus reducing the functional practicality of the overall roving frame for detecting broken yarns. Content of the Utility Model

[0019] Compared with the prior art, the beneficial effect of the present utility model is that: the roving frame facilitating automatic broken yarn detection

[0020] (1) In this case, by setting the broken yarn detection structure, the problem that the roving frame set in the above case does not have the function of detecting broken yarn is solved, thereby reducing the functional practicality of the overall roving frame for broken yarn detection. When the acrylic yarn bypasses the guide roller and the wire guiding roller, at this time, it drives the wire guiding roller to move downward obliquely. When the wire guiding roller moves downward obliquely under force, it synchronously drives the torsion spring to rotate. When the torsion spring rotates under force, it drives the trigger rod to be separated from the trigger module under force. When the acrylic yarn is wound normally, at this time, both the trigger rod and the trigger module are in a separated state. When the acrylic yarn winding is broken, at this time, the trigger rod contacts the trigger module to play a role in broken yarn alarm;

[0021] (2) By setting the body structure, the situation that the acrylic yarn is easily separated from the guide roller and the wire roller after yarn breakage is solved. After the acrylic yarn is separated due to yarn breakage, when the wire roller moves upward under the elastic force and contacts the chuck, the acrylic yarn after yarn breakage is squeezed and limited to prevent detachment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-6 , the present utility model provides a technical solution: a roving frame for facilitating automatic detection of yarn breakage, such as Figure 1 , Figure 2 and Figure 3As shown in the figure, it includes an organism structure 1. The organism structure 1 includes a roving frame body 101 as the main body. A T-shaped bearing frame 102 is fixed on the roving frame body 101. At the same time, a conveying roller 103 is rotatably installed in front of the whole T-shaped bearing frame 102. There are 12 groups of conveying rollers 103, and the conveying rollers 103 are installed at equal intervals. When there are 12 groups and 24 of the above-mentioned components are set, it not only reflects the practicality of the installation of the above-mentioned components, but also reflects the equal-distance distribution and yarn guiding and conveying properties of the above-mentioned components. And when there are 12 groups and 24 of the above-mentioned components are set, it also reflects the symmetry of the above-mentioned components about the transverse axis of the T-shaped bearing frame 102. A trigger module 104 is fixed below the T-shaped bearing frame 102. A L-shaped rod 105 is fixed on one side of the trigger module 104. At the same time, a chuck 106 is fixed directly in front of the L-shaped rod 105. There is 1 group of chucks 106, and the chuck 106 is vertically installed directly above the wire guide roller 206. When there is 1 group of the above-mentioned components, it reflects the vertical installation property of the above-mentioned components directly above the wire guide roller 206, and also reflects the property of the above-mentioned components to squeeze and limit the running-away yarn of the broken yarn on the wire guide roller 206. And when there is 1 group of the above-mentioned components, it reflects the synchronous yarn clamping and limiting and the distinguishing yarn clamping and limiting properties of the above-mentioned components.

[0031] Furthermore, in the above solution, an alarm 107 is fixed above the T-shaped bearing frame 102, and the alarm 107 is arranged in a symmetrical manner.

[0032] As Figure 4 、 Figure 5 and Figure 6 shown in the figure, a broken yarn detection structure 2 is fixedly installed on the organism structure 1. The broken yarn detection structure 2 includes a concave block 201 with an installation groove 202 on the inner side. A guide wheel roller 203 is rotatably installed directly in front of the concave block 201. At the same time, the concave block 201 is fixedly installed below the bottom of the T-shaped bearing frame 102. The installation groove 202 is rotatably connected to an opening frame 205 through a torsion spring 204. A wire guide roller 206 is rotatably installed directly in front of the opening frame 205. At the same time, a trigger rod 207 is fixedly installed on the opening frame 205. Among them, the above-mentioned components constitute an elastic rotation adjustment structure. When using the elastic rotation adjustment structure composed of the above-mentioned components, it effectively plays an elastic rotation and broken yarn elastic recovery effect on the opening frame 205 and the wire guide roller 206.

[0033] In the above solution, when the acrylic yarn bypasses the guide roller 203 and the wire guide roller 206, it drives the wire guide roller 206 to move downward obliquely. During the process of the wire guide roller 206 moving downward under force, the torsion spring 204 is synchronously driven to rotate. When the torsion spring 204 rotates under force and drives the trigger rod 207 to be separated from the trigger module 104 under force, when the acrylic yarn is wound normally, the trigger rod 207 and the trigger module 104 are in a separated state. When the acrylic yarn breaks during winding, the trigger rod 207 contacts the trigger module 104 to achieve yarn breakage alarm. At the same time, the chuck 106 contacts the wire guide roller 206 under force to squeeze the broken yarn to prevent the yarn from running away.
