Description

Technical Field

[0001] The invention relates to the technical field related to polyester filament processing, and specifically provides a tangent component for winding polyester filaments. Background Art

[0002] Polyester filament is made of polyester. Polyester is an important variety of synthetic fiber and the trade name of polyester fiber in my country. It is made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) as raw materials, and is made of polyethylene terephthalate (PET) through esterification or ester exchange and polycondensation reaction. The fiber is made by spinning and post-processing. The so-called polyester filament is a thread with a length of more than one kilometer, and the filament is wound into a ball; polyester has a wide range of uses and is widely used in the manufacture of clothing and industrial products. Flame-retardant polyester has a wide range of applications due to its flame retardancy. In addition to playing an irreplaceable role in industrial textiles, building interiors, and interior decoration of vehicles, it also plays a lot of roles in the field of protective clothing.

[0003] The existing polyester filament needs to be wrapped around the outside of the bobbin after processing and then transported. However, the existing tangent method is easy to cause the tangent to have a head, resulting in the internal separation of multiple strands of synthetic polyester filaments. In order to make up for the existing technology, Chinese invention patent CN218593084U provides a tangent machine for polyester line production, which relates to the technical field of polyester line tangent machines, including a test table assembly, the upper surface of the table assembly is provided with a cutting anti-loosening assembly, and one side of the cutting anti-loosening assembly is provided with a fixed clamping assembly. The utility model solves the problem that polyester filaments are usually made of multiple strands twisted together. The problem of easy wire loosening and dispersion after cutting is solved by passing the polyester wire wound on one end of the polyester wire reel through the lower end of the supporting frame plate, and then winding it on the outer surface of the bobbin. When the wire is wound through the bobbin, the control button is started, and the electric lifting rod drives the sliding block, and the sliding block drives the wire cutting blade and the electric heating wire to move downward. There are two groups of electric heating wires, which are respectively arranged on both sides of the wire cutting blade, so that the incision can be heat treated while cutting, so that the incision is melted and condensed, and the situation of loosening and dispersion is avoided. The structure is simple, easy to use and reasonably designed.

[0004] The above patent has the following defects: when the polyester filament passes through the cutting blade, the two ends of the heating wire will have slag on the surface of the heating wire due to the hot melt property of the plastic, and the tensioned wire will naturally fall off and shift after cutting. When the winding tension is tight, the wire needs to be rethreaded, which is inconvenient. Therefore, we need to improve the above problems. Summary of the invention

At this time, the worker can drive the telescopic rod to slide to the outside of the capacitor wire according to the situation, and then prompt the arc-shaped elastic scrapers on both sides to clean the cooled slag, thereby facilitating subsequent continuous operations. This method can make threading and winding more convenient, and the slag on the surface of the capacitor wire can be removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The wire clamping member includes two sets of elastic ropes 33, which are respectively installed at two ends of the inner side of the wire box 35; The elastic rope 33 can ensure that the wire will not move too much during the wiring process inside the wire box 35.

[0021] The line-retaining assembly includes clamping rods 30 respectively slidably mounted on the outer sides of the two ends of the U-shaped rod 22, and a resistance wheel 32 is rotatably mounted on the inner side of one end of the two clamping rods 30. A reverse screw 29 is commonly arranged on the outer sides of the ends of the two clamping rods 30 away from the resistance wheel 32. The reverse screw 29 is commonly installed between the two groups of U-shaped platforms 20, and the two groups of clamping rods 30 are threadedly matched with the reverse screw 29. A fixed shaft is fixedly mounted on one end of the reverse screw 29, and the fixed shaft is inserted into the inner side of the U-shaped platform 20 on the corresponding side away from the outer side of the end of the reverse screw 29, and a gear 28 is fixedly sleeved on the outer side of the fixed shaft.

[0022] When the reverse screw 29 rotates, the clamp rod 30 corresponding to the thread of the reverse screw 29 will move closer to or away from each other under the sliding contact of the U-shaped rod 22, and the end of the reverse screw 29 away from the fixed axis is in rotational cooperation with the U-shaped platform 20 on the other side.

[0023] The tangent assembly includes a rod 17 slidably mounted on the inner side of a base 27, a cylinder 19 is provided on the lower surface of the rod 17, the cylinder 19 is fixedly mounted on the lower surface of the base 27, and the telescopic end of the cylinder 19 passes through the inner side of the base 27 and is connected to the rod 17, a jacket 21 is fixedly mounted above both ends of the rod 17, a heater 23 is installed between the two jackets 21, and a capacitor wire 24 is installed above the outer sides of the two jackets 21; The cylinder 19 can drive the lever 17 to move up and down inside the base 27, so that the jacket 21 above both ends of the lever 17 can drive the heater 23 and the capacitor wire 24 to rise and fall synchronously, and the capacitor wire 24 is linearly connected to the heater 23; The two jackets 21 are both fixedly mounted with connecting blocks 25 on the outside, and the connecting blocks 25 corresponding to the positions of the gears 28 are fixedly connected with the fixing blocks 18 on the outside, and the fixing blocks 18 are fixedly connected with the racks 26 on the outside, and the racks 26 and the gears 28 are meshed, and the capacitor wire 24 is located below the reverse screw 29; With the fixed block 18 and the connecting block 25 installed, the rack 26 can extend upward from the bottom. Since the capacitor wire 24 is arranged below the reverse screw 29, the lifting distance is equal to the distance between the corresponding two clamping rods 30. When the capacitor wire 24 contacts the wire, the two clamping rods 30 also drive the corresponding wheels 32 to clamp the wire. In order to achieve this effect, it can be driven by an externally connected precise position sensor and controller.

[0024] A telescopic rod 39 is slidably mounted on the lower inner side of the U-shaped rod 22 , and elastic scrapers 31 are mounted on both sides of the telescopic end of the telescopic rod 39 .

[0025] The elastic scraper 31 is arc-shaped and convex inside, so that it can fit the surface of the capacitor wire 24 to scrape off the slag. The telescopic rod 39 can be composed of a common automatically telescopic rod body.

[0026] The driving mechanism includes a screw rod 16 rotatably mounted on the inner side of the top seat 2 , one end of the screw rod 16 passes through the outer side of the top seat 2 and the end is connected to the first motor 3 , the slide 4 and the screw rod 16 are threadedly matched, and the first motor 3 is fixedly mounted on the outer side of one end of the top seat 2 .

[0027] After the first motor 3 is connected to the power supply, it can drive the screw rod 16 to rotate, so that the slide seat 4 drives the outer support rod 6 to move horizontally inside the top seat 2, so as to meet the use of the component frame 7 to adjust the length of different bobbins in the later stage.

[0028] The lead assembly includes a U-shaped frame 10 fixedly connected to the lower surface of the top seat 2, an insertion shaft 9 is inserted inside the U-shaped frame 10, and a wire wheel 8 is movably arranged outside the insertion shaft 9; The inner side of the wire wheel 8 can guide the wire to assist in threading.

[0029] A connecting plate 13 is fixedly connected to the outer wall of one side of the bracket 1, and a second motor 15 is fixedly installed on the outer side of the connecting plate 13. The output end of the second motor 15 extends to the inner side of the connecting plate 13 and a rotating shaft 12 is installed on the end thereof. A bobbin 14 is arranged on the outer side of the rotating shaft 12. After the second motor 15 is connected to a power source, it drives the rotating shaft 12 to rotate. The rotating shaft 12 can cause the bobbin 14 to rotate and wind the wire. The bobbin 14 and the rotating shaft 12 are fixed by a positioning pin.

[0030] It should be noted that the capacitor wire 24 and the heater 23 are prior art, so they will not be described in detail here.

[0031] Working principle: When in use, the wire is pulled by the worker, passes through the lead assembly, the wire box 35, and the two wheels 32 in turn, and then the wire is wrapped around the outside of the wire drum 14. Then the second motor 15 drives the rotating shaft 12 to rotate, and the wire drum 14 automatically reels the wire on the outside. After the winding of the wire drum 14 is completed, the cylinder 19 pushes the rod 17 to move up, causing the two jackets 21 to drive the capacitor wire 24 and the heater 23 to move closer to the outside and below of the wire. During the rising process of the jacket 21, the rack 26 will drive the meshing gear 28 to rotate, and then the fixed shaft will drive the reverse screw 29 to rotate, and the two clamping rods 30 with threaded matching can approach each other, which means that the two wheels 32 can clamp the wire in the center at the edge of the wire box 35 until the capacitor wire 24 rises and connects. When the wire is touched, it is cut off. At this time, under the connection of the wheel 32, the traction wire away from one end of the wire reel 14 is still clamped on the inner side of the wire box 35. The worker can pull out the wire and wrap it around the new wire reel 14 to reel it up again. This method can quickly and effectively cut the wire and prevent the wire from falling off and shifting. During the threading process, the capacitor wire 24, the jacket 21, and the rod 17 all descend, and the corresponding wheel 32 also moves toward both ends. At this time, the worker can drive the telescopic rod 39 to slide to the outside of the capacitor wire 24 according to the situation, and then prompt the arc-shaped elastic scrapers 31 on both sides to clean the cooled slag, thereby facilitating subsequent continuous operations. This method can make threading and reeling more convenient, and also avoids the problem of laborious tangent due to excessive adhesion of slag during the tangent process.
