Description

Technical Field

[0001] The utility model relates to the technical field of yarn conveying, in particular to a yarn rack. Background Art

[0002] The creel is an auxiliary device for conveying yarn to the knitting equipment, which can guide the conveying of several yarns in an orderly manner. See the "Spinning Creel" disclosed in the announcement number CN107814253B. In this scheme, the first support rod or the second support rod is used to support the yarn bobbin. However, since the yarn is relatively small, the yarn may break during the conveying process, resulting in the broken yarn bobbin being unable to continue conveying the yarn to the knitting equipment, and it is not easy to be detected, thereby affecting the quality of the woven fabric. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a yarn rack capable of judging whether there is a yarn breakage situation.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a yarn rack, including a yarn support frame and a detection component; a plurality of expansion shafts are rotatably arranged on the yarn support frame, and the detection component includes a rotation detector and a prompter communicatively connected to the rotation detector; a detection component is arranged on the yarn support frame corresponding to each expansion shaft.

[0005] Furthermore, the expansion shaft includes an outer sleeve, a movable block and a core shaft; one end of the outer sleeve is rotatably connected to the yarn support frame, the movable block is movably arranged on the outer sleeve along the radial direction of the outer sleeve, the movable block has an abutment portion located in the inner cavity of the outer sleeve, and the movable block has a supporting portion that can be away from the outer side wall of the outer sleeve; the core shaft can extend into the inner cavity of the outer sleeve to contact the abutment portion, and keep the supporting portion away from the outer side wall of the outer sleeve.

[0006] Furthermore, the core shaft is in a truncated cone shape, the small diameter end of the core shaft can extend into the inner cavity of the outer sleeve and contact the abutment portion, and the large diameter end of the core shaft is detachably connected to the barrel opening of the outer sleeve.

[0007] Furthermore, the large diameter end of the core shaft is provided with an end cover, and the end cover is sleeved on the outer side wall of the barrel opening of the outer sleeve.

[0008] Furthermore, the yarn support frame is provided with a plurality of lead-in rows, and the lead-in rows are provided with a plurality of threading holes.

[0009] The beneficial effect of the utility model is that, different from the prior art, an expansion shaft and a detection component are rotatably arranged on the yarn support frame. The yarn tube is supported by the expansion shaft, and the yarn on the yarn tube is pulled out and rotated, which can drive the expansion shaft to rotate. Then, a rotation detector is used to detect whether the expansion shaft rotates. If a wire break occurs, the yarn tube cannot be rotated by the weaving device pulling out the yarn, that is, the yarn tube will not drive the expansion shaft to rotate. Then, when the rotation detector detects that the expansion shaft does not rotate, it will control the prompter to issue a prompt to remind the on-site personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0018] Please refer to Figure 1 As shown, the utility model is a yarn frame, including a yarn support frame 1 and a detection component 2; a plurality of expansion shafts 11 are rotatably arranged on the yarn support frame 1, and the detection component 2 includes a rotation detector 21, and a prompter 22 communicatively connected to the rotation detector 21; a detection component 2 is arranged on the yarn support frame 1 corresponding to each expansion shaft 11.

[0019] Working principle: Due to the expansion and tensioning ability of the expansion shaft 11, the yarn tube can be fixed on the expansion shaft 11, so that the yarn on the yarn tube is pulled out and rotated, and at the same time, the expansion shaft 11 can be driven to rotate. Therefore, taking advantage of this feature, a detection component 2 is added to the yarn support frame 1 corresponding to each expansion shaft 11, and the rotation detector 21 detects whether the expansion shaft 11 is rotating. If the wire is broken, the yarn tube cannot be rotated by the weaving equipment by pulling out the yarn, that is, the yarn tube will not drive the expansion shaft 11 to rotate. Then, the rotation detector 21 detects that the expansion shaft 11 has not rotated, and it will control the prompter 22 to issue a prompt to remind on-site personnel.

[0020] Among them, the rotation detector 21 can be a photoelectric sensor, a Hall sensor, a speed sensor or the like for detecting the speed. Taking the use of the Hall sensor as an example, the Hall sensor is set on the yarn support frame 1, and a magnetic block is set on the expansion shaft 11. Within the specified time, the magnetic block on the expansion shaft 11 can pass through the detection end of the Hall sensor, which means that the yarn tube is outputting the yarn normally. If the magnetic block on the expansion shaft 11 does not pass through the detection end of the Hall sensor within the specified time, it means that the yarn on the yarn tube is broken. At this time, the Hall sensor will control the prompter 22 to issue a prompt to remind the on-site personnel. Preferably, the prompter 22 adopts an integrated sound and light prompting method, which reminds the on-site personnel by sound and informs the on-site personnel by light source where the yarn tube is broken.

[0021] Please refer to Figure 2 and Figure 3 As shown, further, the expansion shaft 11 includes an outer sleeve 111, a movable block 112 and a core shaft 113; one end of the outer sleeve 111 is rotatably connected to the yarn support frame 1, and the movable block 112 is movably arranged on the outer sleeve 111 along the radial direction of the outer sleeve 111, and the movable block 112 has an abutment portion 1121 located in the inner cavity of the outer sleeve 111, and the movable block 112 has a support portion 1122 that can be away from the outer wall of the outer sleeve 111; the core shaft 113 can extend into the inner cavity of the outer sleeve 111 and contact the abutment portion 1121, and keep the support portion 1122 away from the outer wall of the outer sleeve 111.

[0022] It can be seen from the above description that in order to facilitate the rapid replacement of the yarn bobbin, the core shaft 113 is inserted and pulled out to control the movement of the movable block 112 on the outer sleeve 111 to achieve the expansion and contraction of the expansion shaft 11.

[0023] Please refer to Figure 2 As shown, further, the core shaft 113 is in a truncated cone shape, the small diameter end of the core shaft 113 can extend into the inner cavity of the outer sleeve 111 and contact the abutment portion 1121, and the large diameter end of the core shaft 113 is detachably connected to the barrel mouth of the outer sleeve 111.

[0024] As can be seen from the above description, the core shaft 113 is in a truncated cone shape, which can facilitate the contact between the abutment portion 1121 and the shaft body of the core shaft 113 when the core shaft 113 is inserted into the inner cavity of the outer sleeve 111. As the core shaft 113 continues to penetrate into the inner cavity of the outer sleeve 111, the support portion 1122 gradually moves away from the outer wall of the outer sleeve 111.

[0025] Please refer to Figure 2 As shown, further, the large diameter end of the core shaft 113 is provided with an end cover 1131 , and the end cover 1131 is sleeved on the outer side wall of the barrel opening of the outer sleeve 111 .

[0026] It can be known from the above description that by sleeve-mounting the end cover 1131 on the outer wall of the tube opening of the outer sleeve 111 , the core shaft 113 can be quickly fixed on the outer sleeve 111 .

[0027] Please refer to Figure 1 and Figure 4 As shown, further, the yarn support frame 1 is provided with a plurality of lead-in rows 12 , and the lead-in rows 12 are provided with a plurality of threading holes 121 .

[0028] As can be seen from the above description, the yarns are introduced into the braiding device through the threading holes 121 on the lead-in row 12 to ensure the orderly delivery of multiple yarns.
