Description

Technical Field

[0001] The present invention belongs to the field of yarn spinning, and particularly relates to a horizontal twisting machine. Background Art

[0002] With the increasing demand for high-count yarns, high-density fabrics, and functional yarns in the textile industry, traditional vertical twisting machines have limitations in processing efficiency and yarn quality. Due to its horizontal layout and mechanical structure characteristics, the horizontal twisting machine is more suitable for the processing requirements of large package and high-twist yarns, especially in fields such as yarn-dyed fabrics and non-iron fabrics that have high requirements for yarn strength and appearance.

[0003] In a horizontal twisting machine, the yarn is led out from the creel, horizontally transported to the twisting area through a yarn guide; the yarn first enters a horizontally placed spindle rotor and is initially twisted as the spindle rotates at high speed; then the yarn is secondarily twisted by a yarn storage disc in a horizontal yarn guiding path to form a double-twist structure, further enhancing the yarn strength and compactness.

[0004] After the yarn is twisted, internal stress is generated in the fibers due to the twisting. When heated, the fiber temperature rises above the glass transition temperature, the molecular chain segments become more active, the original weak secondary valence bonds are broken, and the fiber molecules are rearranged under the action of heat and the internal stress is released, making the twist distribution more uniform and reducing the subsequent tendency to untwist. After the heating stage is completed, the yarn also needs to be quickly cooled below the glass transition temperature, at which time the movement of the fiber molecular chains is "frozen" and the new arrangement state is fixed, thus stabilizing the twist in the adjusted form.

[0005] Therefore, it is necessary to heat and cool the twisted yarn to stabilize the twist, and for this purpose, a horizontal twisting machine is proposed. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a horizontal twisting machine, which solves the problems in the prior art.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] A horizontal twisting machine includes a bottom plate fixed on a machine base, and a heating mechanism and a cooling mechanism are sequentially arranged on the upper end of the bottom plate along the yarn conveying direction;

[0009] The heating mechanism includes two first mounting plates that can slide synchronously and reversely along a direction perpendicular to the yarn conveying direction. A first L-shaped plate is fixed on each of the two first mounting plates and can enclose an annular space; a heater is fixed on the inner side of each of the two right-angle faces of the first L-shaped plate;

[0010] The cooling mechanism includes two second mounting plates that can slide synchronously and in opposite directions perpendicular to the yarn conveying direction. A second L-shaped plate is fixed on each of the two second mounting plates and can enclose an annular space. A plurality of second air blowing pipes are installed on both right-angled surfaces of the second L-shaped plate to blow air on the yarn for cooling.

[0011] Further, a plurality of first air blowing pipes are installed on both right-angled surfaces of the first L-shaped plate. The air blown by the first air blowing pipes reaches the yarn after being heated by a heater.

The baffle assembly includes two connecting rods respectively fixed to the two first mounting plates. A fixing rod is fixed on each of the two connecting rods. A baffle is installed on each of the two fixing rods.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0033] A horizontal twisting machine includes a machine base. As Figure 1 shown, a bottom plate 1 is fixed on the machine base. Along the transmission direction of the yarn at the upper end of the bottom plate 1, a heating mechanism 2 and a cooling mechanism 3 are sequentially arranged to heat the stress-relieved twisted yarn and cool and shape it respectively.

[0034] As Figure 2 and Figure 3 shown, the heating mechanism 2 includes two first mounting plates 21 that can slide synchronously and reversely on the upper end of the bottom plate 1, and the sliding direction is perpendicular to the transmission direction of the yarn. A heating component 22 is arranged at the upper end of each of the two first mounting plates 21. The heating component 22 includes a first L-shaped plate 221 fixed to the upper end of the first mounting plate 21. When the two first mounting plates 21 approach synchronously, the two first L-shaped plates 221 can enclose a circular space, and the yarn can pass through the circular space and be heated in the circular space.

[0035] A heater 22 is fixed to the inner side of each of the two right-angled surfaces of the first L-shaped plate 221. A heating tube is arranged on the heater 22 to generate heat after being powered on, thereby realizing the heating of the yarn. In addition, a plurality of first air blowing pipes 223 are installed on both right-angled surfaces of the first L-shaped plate 221. The first air blowing pipes 223 are connected to an air blowing pump. After the blown air is heated by the heater 22, it reaches the yarn to improve the heating effect.

[0036] When it is necessary to install the yarn or repair the heater 22, by controlling the two first mounting plates 21 to move away from each other, the circular space is opened to facilitate subsequent installation and repair operations.

[0037] In this embodiment, both of the two first mounting plates 21 are slidably connected to the bottom plate 1, and the sliding direction is perpendicular to the transmission direction of the yarn. Two first fixing plates 23 are arranged at the upper end of the bottom plate 1. A first lead screw 24 is rotatably connected between the two first fixing plates 23. The two ends of the first lead screw 24 are respectively provided with a first external thread 241 and a second external thread 242 with opposite helix directions and equal pitches. The first external thread 241 and the second external thread 242 respectively penetrate through the two first mounting plates 21 and are threadedly connected thereto. By arranging a motor on one of the first fixing plates 23 to drive the first lead screw 24 to rotate, the synchronous reverse sliding of the two first mounting plates 21 can be realized.

[0038] Moreover, in order to ensure the stability of the two first mounting plates 21 after position adjustment, the first lead screw 24 needs to have self-locking, that is, the lead angles of the first external thread 241 and the second external thread 242 are both smaller than the equivalent friction angle.

[0039] Of course, the method of controlling the synchronous reverse sliding of the two first mounting plates 21 includes but is not limited to the structure of the first lead screw 24 in this embodiment. In some embodiments, two cylinders can also be arranged on the bottom plate 1 to drive the two first mounting plates 21 to slide synchronously in the reverse direction.

[0040] As Figure 4 shown, the cooling mechanism 3 includes two second mounting plates 31 that can slide synchronously in the reverse direction, and the sliding direction is perpendicular to the conveying direction of the yarn. A second L-shaped plate 32 is fixed to the upper end of each of the two second mounting plates 31. By controlling the synchronous approach of the two second mounting plates 32, the two second L-shaped plates 32 can also enclose an annular space, and the yarn passes through the annular space and is cooled therein; a plurality of second air pipes 33 are arranged on both right-angled surfaces of the second L-shaped plate 32. The second air pipes 33 are communicated with an air blowing pump and can blow air to cool the yarn.

[0041] In addition, a cooling assembly 4 is arranged between the two second L-shaped plates 32. As Figure 5 shown, the cooling assembly 4 includes a spiral water pipe 41, and the yarn passes through the spiral water pipe 41. Two support rods 42 are arranged at the upper end of the bottom plate 1 to fix the spiral water pipe 41. Circulating cold water flows through the bolt water pipe 41. The air blown by the second air pipe 33 is cooled after passing through the spiral water pipe 41 and then reaches the yarn to cool and shape the yarn.

[0042] When it is necessary to repair the second air pipe 33 and the bolt water pipe 41, the two second mounting plates 31 can be controlled to move away from each other, so that the annular space enclosed by the two second L-shaped plates 32 is opened to facilitate the repair operation.

[0043] In this embodiment, both of the two second mounting plates 31 are slidably connected to the bottom plate 1, and the sliding direction is perpendicular to the conveying direction of the yarn. Two second fixing plates 34 are arranged at the upper end of the bottom plate 1. A second lead screw 35 is rotatably connected between the two second fixing plates 34. Third external threads 351 and fourth external threads 352 with opposite helix directions and equal pitches are arranged at both ends of the second lead screw 35. The third external thread 351 and the fourth external thread 352 respectively penetrate through the two second mounting plates 31 and are threadedly connected thereto. By arranging a motor on one of the second fixing plates 34 to drive the second lead screw 35 to rotate, the synchronous reverse sliding of the two second mounting plates 31 can be realized.

[0044] Moreover, to ensure the stability of the two second mounting plates 312 after position adjustment, the first lead screw 35 needs to have self-locking property, that is, the thread lead angles of the third external thread 351 and the fourth external thread 352 are both smaller than the equivalent friction angle.

[0045] In other embodiments, two cylinders can also be provided on the base plate 1 to respectively drive the two second mounting plates 31 to slide synchronously and in opposite directions.

[0046] It is worth mentioning that when the cooling mechanism 3 and the heating mechanism 2 are operating simultaneously, the cold air generated by the cooling mechanism 3 enters the heating mechanism 2, thus affecting the heating effect. Therefore, in this embodiment, a baffle assembly 5 is provided between the heating mechanism 2 and the cooling mechanism 3 to isolate the air path and reduce the mutual influence effect;

[0047] As Figure 6 shown, the baffle assembly 5 includes two connecting rods 51, the two connecting rods 51 are respectively fixed to the two first mounting plates 21, a fixing rod 52 is respectively fixed on the two connecting rods 51, and a baffle 53 is respectively installed on the two fixing rods 52. When the two first L-shaped plates 221 enclose to form an annular space, the two baffles 53 are spliced to block the cold air in the cooling mechanism 3 from entering the heating mechanism 2;

[0048] Moreover, as Figure 6 shown, a semi-circular groove 531 is respectively opened on one side of the two baffles 53 close to each other. When the two baffles 53 are spliced, the two semi-circular grooves 531 are spliced into a through hole, and the yarn can pass through the through hole and enter the cooling mechanism 3.

[0049] It should be noted that when installing the yarn, control the two first L-shaped plates 221 to move away from each other. At this time, the two baffles 53 will also move away from each other, so as to facilitate the installation of the yarn into the heating mechanism 2.

[0050] In this embodiment, as Figure 6 shown, two guide rods 532 are provided on the side of the baffle 53 facing away from the semi-circular groove 531. The guide rods 532 penetrate through the fixing rod 52 and are slidably connected thereto. A spring 54 is sleeved on the guide rods 532, and the two ends of the spring 54 are respectively fixed to the fixing rod 52 and the baffle 53, so as to realize the elastic connection between the baffle 53 and the fixing rod 52; thus, before the two first L-shaped plates 221 enclose to form an annular space, the two baffles 53 can be spliced to improve the splicing tightness;

[0051] A frustum 533 is provided at one end of the guide rod 532 away from the baffle 53. The diameter of the frustum 533 is larger than that of the guide rod 532. Under the elastic force of the spring 54, the frustum 533 has a tendency to approach the fixing rod 52 and can prevent the guide rod 532 from detaching from the fixing rod 52.

[0052] Working principle:

[0053] By sequentially arranging a heating mechanism 2 and a cooling mechanism 3 along the conveying direction of the yarn, the twisted yarn is heated to remove stress and cooled and shaped respectively, so as to achieve the purpose of stabilizing the twist. By arranging a baffle assembly 5 between the heating mechanism 2 and the cooling mechanism 3, and two baffles 53 that can move synchronously with two first mounting plates 21 are arranged in the baffle assembly 5, to isolate the air path and reduce the mutual influence between the heating mechanism 2 and the cooling mechanism 3; at the same time, it is also convenient to install the yarn into the heating mechanism 2 during maintenance.
