DETAILED DESCRIPTION

[0025] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0026] refer to Figures 1 to 9

[0027] A multi-strand yarn close-up mechanism comprises a frame 10, on which a plurality of longitudinal guide rollers 20 driven to rotate by a driving mechanism are installed at intervals along the horizontal direction of the frame, a guide channel 30 with adjustable spacing is arranged at the rear side of the longitudinal guide roller, a plurality of guide sleeves 40 with adjustable positions are installed at intervals along the longitudinal direction at the lower side between the guide channel and the longitudinal guide roller, a reversing rod 50 is arranged on the table at the front side of the frame, a guide channel 60 with a gradually narrowing width is arranged at the front side of the reversing rod, and a clamping mechanism 70 for clamping the yarn is arranged at the front end of the guide channel. The yarn in the yarn placing container placed under the guide sleeve passes through the guide sleeve, and then bypasses the upper side of the longitudinal guide roller and is transported forward. The yarn transported forward is positioned and guided by the guide channel, and finally, multiple yarns are sent into the guide channel by the longitudinal guide roller and the reversing rod at the front side to be close together, and then are compressed by the clamping mechanism to make the yarns fit more closely.

[0028] In this embodiment, in order to better drive the yarn to be transported forward, the longitudinal guide roller is provided with a plurality of longitudinal grooves 21 at intervals along the circumferential direction. The driving mechanism for driving the longitudinal guide roller may include a gear mounted on one end of the longitudinal guide roller, and the gear is driven by a motor via a chain to realize the rotation of the longitudinal guide roller. The driving mechanism may also include a synchronous pulley disposed in the middle of the longitudinal guide roller, and driven by a motor via a synchronous belt to realize the synchronous rotation of the longitudinal guide roller.

[0029] In this embodiment, in order to facilitate the spacing adjustment of the guide channel, a fixing frame 80 is provided at the rear side of the longitudinal guide roller, and a longitudinal slide groove 81 is provided at the upper end of the fixing frame. A plurality of columns 31 whose lower ends are slidably matched with the longitudinal slide groove are provided on the fixing frame at intervals, and the guide channel 30 is formed between two adjacent columns, and the lower ends of the columns are locked with the fixing frame by the fixing bolts 32. Only one wire strip passes through each guide channel.

[0030] In this embodiment, in order to adjust the position of the guide sleeve, a longitudinal groove 82 is provided on the lower side of the fixing frame, and a connecting angle plate 42 is installed on one side wall of the guide sleeve via a fixing rod 41. The connecting angle plate is slidably connected to the longitudinal groove via a locking bolt 43 and locked with a nut. After adjusting the position of the guide sleeve according to the requirements, the position of the guide sleeve is locked by the locking bolt.

[0031] In this embodiment, the middle portion of the guide sleeve is recessed inwardly to form a trumpet-like shape at both ends, so as to facilitate the introduction and export of the wire strip.

[0032] In this embodiment, in order to facilitate the wire to pass through the guide channel, the reversing rod is arranged longitudinally, one end of the reversing rod is hinged to the table through a hinge seat 51, and a slot 52 for the other end of the reversing rod to be placed is fixed on the table. When the wire is initially installed, after the wire passes through the guide channel, the other end of the reversing rod is inserted into the slot.

[0033] In this embodiment, in order to allow multiple wires to be brought together better, the guide channel includes a slot plate 61 with a bell mouth at the rear end and a contracted mouth at the front end. The front end of the slot plate has an extension portion 62 extending forward to the entrance of the clamping mechanism, so that the first and second pinching wheels can avoid gaps on both sides of the output end of the guide channel. The upper side of the slot plate is covered with a top plate 63 to form a guide channel. The rear end of the top plate has a guide portion 64 extending backward and tilting. After the multiple wires pass through the guide channel, they are brought together and can be better fed into the clamping mechanism for compaction.

[0034] In this embodiment, the clamping mechanism includes a first pinch wheel 71 and a second pinch wheel 72 which are arranged horizontally and rotate in opposite directions. The first pinch wheel is provided with an annular groove 73, and the side of the second pinch wheel extends into the annular groove. The table is provided with a first scraper 74 abutting against the annular groove, a second scraper 75 abutting against the side of the lower part of the first pinch wheel, and a third scraper 76 abutting against the side of the annular flange at the lower part of the second pinch wheel. The silk thread passes through the annular groove, and the second pinch wheel cooperates with the annular groove to realize the compression of the silk thread and forward clamping, so as to be sent into the silk thread storage barrel for collection. The silk thread adhering to the surface of the first pinch wheel, the surface of the annular groove, and the surface of the second pinch wheel is scraped off by using the first scraper, the second scraper, and the third scraper.

[0035] In this embodiment, the first pinch wheel and the second pinch wheel are driven to rotate by small motors respectively.

[0036] In this embodiment, in order to scrape off the wire that has not been sent into the guide channel, a plastic rotating plate 78 is installed on the upper end of the first pinch wheel via a vertical fixed shaft 77. The length of the plastic rotating plate is 2 to 3 times the diameter of the first pinch wheel. The first scraper, the second scraper and the third scraper are all plastic plates to prevent the scraper from scraping off the first pinch wheel and the second pinch wheel.

[0037] In this embodiment, a fixing plate 90 is installed at the front end of the frame, and conical comb teeth 91 are fixed to the lower side of the fixing plate at longitudinal intervals, and a yarn channel is formed between two adjacent conical comb teeth so that the yarn can pass through the yarn channels and be combed.

[0038] In this embodiment, a thread placing container 1 is arranged below the guide sleeve, and the thread placing container can be a cotton strip tube CN204454082U which is easy to clean.
