Description

Technical Field

[0001] The utility model relates to the field of production devices for covered yarns, in particular to a yarn guiding device. Background Art

[0002] A spinning frame is a spinning device that draws roving into fine yarn. Usually, a spinning frame can have multiple spindles. Each spindle has a bobbin driven by a rotating spindle, and the drawn spun yarn is wound onto the bobbin. This also requires that each spindle must also be equipped with a corresponding roving core for drafting. These roving cores are generally placed between the feed wheels and separated by isolation rods to prevent the positions of multiple roving cores from shifting when being pulled. Since the isolation rods are often fixedly installed between the feed wheels, before the roving core is placed on the feed wheel, the staff often needs to compare the length of the roving core with the distance between the two isolation rods in advance, and then put it in the appropriate position between the feed wheels, which is more time-consuming.

[0039] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0040] The utility model embodiment provides a yarn guide device, please refer to Figure 1-Figure 3 The yarn guiding device comprises a thread loosening unit, a thread feeding unit and a frame 5. Among them,

[0041] The wire loosening unit has a support plate and a feed column. The support plate is installed on the feed column. The support plate includes a support plate body 3, an isolation rod assembly 21 and a limit assembly 22. The support plate body 3 is provided with a through hole 300. The isolation rod assembly 21 includes an isolation rod 210 and a rotating block 211. The isolation rod 210 is matched with the through hole 300 and slides in the direction of the through hole 300. The space between two adjacent isolation rods 210 is used for placing the roving core 6. The size of the rotating block 211 is larger than the diameter of the through hole 300. The rotating block 211 is sleeved and threadedly connected to the outer wall of the isolation rod 210. The limit assembly 22 has a spiral rod 220. The spiral rod 220 is threadedly connected to the side wall of the support plate body 3, and is used to limit the movement of the roving core 6 in the direction of the through hole 300.

[0042] The thread delivery unit comprises an input roller 40. The input roller 40 is wound with the thick yarn drawn by the thread loosening unit.

[0043] By adjusting the distance between two adjacent isolation rods 210 and the height of the isolation rods 210 above the support plate body 3 , a plurality of roving cores 6 of different specifications can be positioned and placed at the support plate body 3 arbitrarily.

[0044] Specifically,

[0045] The wire loosening unit comprises two feeding columns and a supporting plate. The supporting plate is installed between the two feeding columns.

[0046] The feed column includes a column body 102 and two extensions 101. The extensions 101 are connected to the two ends of the column body 102. The feed column includes a first feed column 11 and a second feed column 10. A rotating assembly is connected to the extension 101 of the second feed column 10. The rotating assembly includes a fixed block 130 and an active column 131. The fixed block 130 is connected to the extension 101. The active column 131 is rotatably connected to the fixed block 130. The active column 131 is externally connected to a driving device.

[0047] The support plate includes a support plate body 3 , an isolation rod assembly 21 and a limit assembly 22 .

[0048] The support plate body 3 includes a bottom plate 30 and two side plates 31. The bottom plate 30 is installed between the two feed columns. A through hole 300 is passed through the bottom plate 30 from top to bottom, and the distribution direction of the through hole 300 is parallel to the extension direction of the support plate body 3. The two side plates 31 are installed at both ends of the bottom plate 30 respectively.

[0049] The isolation rod assembly 21 includes an isolation rod 210 and a rotating block 211. The isolation rod 210 is provided to match the through hole 300. That is, the diameter of the isolation rod 210 is equal to the diameter of the through hole 300, so that the isolation rod 210 can pass through the through hole 300. The isolation rod 210 can move along the through hole 300, so the distance between two adjacent isolation rods 210 is adjustable, so that roving cores 6 of various lengths can be placed between the two adjacent isolation rods 210.

[0050] The rotating block 211 is sleeved and threadedly connected to the outer wall of the isolation rod 210. The size of the rotating block 211 is larger than the diameter of the through hole 300. The isolation rod 210 is arranged to pass through the through hole 300 so that the rotating block 211 sleeved on the isolation rod 210 is connected to the top of the support plate body 3, thereby preventing the isolation rod 210 arranged in the through hole 300 from sliding downward. According to the length of a roving core 6, the spacing between two adjacent isolation rods 210 is adjusted by sliding the isolation rod 210 along the through hole 300. According to the thickness of the roving core 6, the height of the isolation rod 210 above the bottom plate 30 is adjusted by rotating the rotating block 211. Other roving cores 6 are adjusted in the same manner as above and placed on the support plate, so that a plurality of roving cores 6 of different specifications can be positioned and placed arbitrarily on the support plate body 3.

[0051] The limit assembly 22 includes a screw rod 220 and a limit block 221. The screw rod 220 is arranged to match the side plate 31. That is, two screw rods 220 are also arranged. Each screw rod 220 is threadedly connected to the side plate 31. The limit block 221 is connected to one end of the screw rod 220 and is arranged between the screw rod 220 and the isolation rod 210 arranged near the end of the feed column. When the screw rod 220 is rotated clockwise, the limit block 221 approaches the isolation rod assembly 21; conversely, the limit block 221 moves away from the isolation rod assembly 21. When a plurality of roving cores 6 are arranged on the support plate body 3, the two screw rods 220 are rotated clockwise so that the two limit blocks 221 move toward the isolation rod assembly 21 until they are connected with the isolation rod 210. In this way, by limiting the movement of the isolation rod 210 along the direction of the through hole 300, the position displacement of the roving core 6 during traction is limited.

[0052] The wire feeding unit includes an input roller 40, a rotating shaft 41 and a conveyor belt 42. The input roller 40 is arranged near the second feed column 10. The rotating shaft 41 is connected to the end of the input roller 40. The conveyor belt 42 is sleeved on the outer wall of the rotating shaft 41 and the outer wall of the active column 131. When the driving device drives the active column 131 to rotate, the transmission is driven by the conveyor belt 42 to drive the rotating shaft 41 to rotate, and further drives the input roller 40 to rotate. The coarse yarn of the coarse yarn cores 6 of multiple different specifications placed on the support plate body 3 is wound around the input roller 40, and is pulled out to the yarn guide drum as the input roller 40 rotates. The coarse yarn core 6 can enter from the feeding hole of the yarn guide drum, and be wound to the yarn guide drum after coming out from the outlet hole.

[0053] The frame 5 includes two lateral plates 52 and a top plate 51. The top plate 51 is connected to the top of the two lateral plates 52. The two feed columns are installed between the two lateral plates 52 through the extension part 101. Among them, the rotating assembly connected to the extension part 101 of the second feed column 10 is arranged on the outside of the lateral plate 52. The input roller 40 is arranged between the two lateral plates 52, and is rotatably connected to the lateral plate 52 through the rotating shaft 41, and the rotating shaft 41 exposed on the outside of the lateral plate 52 is provided with a mounting part. The mounting part is sleeved by the conveyor belt 42.

[0054] The working method of the embodiment of the present application is as follows:

[0055] According to the specifications of the roving core 6, the distance between two adjacent isolation rods 210 and the height of the isolation rod 210 above the bottom plate 30 are adjusted respectively, so that a plurality of roving cores 6 of different specifications can be positioned and placed at the support plate body 3 at will. Then the spiral rod 220 is rotated clockwise to make the limit block 221 approach the isolation rod assembly 21 until it is connected with the isolation rod 210 provided near the end of the feed column, thereby preventing the roving core 6 from being offset during the traction process.

[0056] The driving device is started to drive the active column 131 to rotate, and the transmission is transmitted through the conveyor belt 42 to drive the rotating shaft 41 to rotate, and further drive the input roller 40 to rotate. The roving of the roving core 6 placed on the support plate body 3 is wound around the input roller 40, and is pulled to the yarn guide drum for winding as the input roller 40 rotates.

[0057] Based on the above embodiments, the advantages of this application are:

[0058] The present application adjusts the distance between two adjacent isolation rods 210 so that multiple roving cores 6 of different lengths can be positioned and placed at the support plate body 3 at will; at the same time, the height of the isolation rod 210 above the bottom plate 30 can be adjusted by the rotating block 211 to match the thickness of the roving core 6. This not only increases the applicability of the yarn guide device, but also saves time for the staff to compare the length of the roving core 6 with the spacing between the isolation rods 210 before positioning and placing it.
