Description

Technical Field

[0001] The utility model relates to the technical field of polyester DTY yarn processing, in particular to a polyester DTY yarn heat setting device. Background Art

[0002] Polyester DTY yarn refers to high-strength, coarse-denier polyester industrial filament with a fineness of not less than 550dtex. It can be divided into high-strength and low-elongation type, high-modulus and low-shrinkage type, high-strength and low-shrinkage type, and active type according to its performance; among them, high-modulus and low-shrinkage polyester industrial yarn has a trend of gradually replacing high-strength and low-elongation polyester industrial yarn in tires and mechanical rubber products due to its excellent properties such as high breaking strength, high elastic modulus, low elongation, and good impact resistance; high-strength and low-elongation polyester industrial yarn has the characteristics of high strength, low elongation, high modulus, and high dry heat shrinkage. It is currently mainly used as tire cord and conveyor belts, canvas warp and vehicle seat belts.

[0003] At present, active polyester industrial yarns have to pass through multiple heating rollers for heating and setting during the heat setting process. However, the space temperature between the heating rollers is much lower than the temperature of the heating roller surface. As a result, the industrial yarns are greatly affected by the temperature difference between the space temperature between the heating rollers and the temperature of the heating roller surface during the heat setting process, resulting in poor heat setting effect, low efficiency and high energy consumption. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Example 1: Reference Figure 1-4 , a polyester DTY yarn heat setting device comprises a box body 1, two holes are symmetrically opened on the box body 1, and the two holes are set for the polyester DTY to pass through. A plurality of line rollers 2 are staggered and rotatably arranged inside the box body 1, and a ring 3 is arranged inside the box body 1 on both sides of the plurality of line rollers 2. Two electric heating tubes 4 are symmetrically fixed on the two rings 3, and the two electric heating tubes 4 are connected in series. The two electric heating tubes 4 work synchronously, and each ring 3 is rotatably arranged on the box body 1, and two first fixed plates 5 are symmetrically fixed on each ring 3, and a bearing 6 is fixed on the two first fixed plates 5. Two second fixed plates 7 are symmetrically fixed on the bearing 6, and the two second fixed plates 7 are fixed on the box body 1. The two second fixed plates 7 and the two first fixed plates 5 are respectively fixed on the inner and outer gear rings of the bearing 6. The setting of the two bearings 6 allows the two rings 3 to be more stably rotatably arranged on the box body 1.

[0023] A driving mechanism is fixed on one of the rings 3, and the driving mechanism is fixed on the box body 1. The driving mechanism includes an arcuate rack 10, and the arcuate rack 10 is fixed on one of the rings 3. The arcuate rack 10 is meshed with a gear 8, and a motor 9 is fixed on the gear 8. The motor 9 is a forward and reverse motor, and the motor 9 is fixed on the box body 1. The forward and reverse motor drives the arcuate rack 10 to rotate forward and reverse alternately through the gear 8, which allows the two electric heating tubes 4 to evenly heat the air around the polyester DTY yarn without being affected by the multiple line rollers 2, thereby ensuring the normal use of the multiple line rollers 2 and the two electric heating tubes 4.

[0024] When in use, when the polyester DTY passes through the box 1 and is supported by multiple wire rollers 2, the motor 9 drives the arc rack 10 to rotate forward and reverse alternately through the gear 8, which allows the two rings 3 to drive the two electric heating tubes 4 to rotate forward and reverse alternately, so that the two electric heating tubes 4 will not touch the multiple wire rollers 2, and the power supply wires on the two electric heating tubes 4 will not be entangled. The two electric heating tubes 4 will evenly heat the air around the polyester DTY yarn, so that the polyester DTY yarn is heated more evenly during heat setting, thereby ensuring the quality and efficiency of the polyester DTY yarn during heat setting.

[0025] Embodiment 2: In embodiment 1, since the gear 8 and the arc-shaped rack 10 are both arranged inside the housing 1, due to the shielding of the housing 1, it is very difficult to lubricate the gear 8 and the arc-shaped rack 10. Figure 1 , 2 , 5 and 6, as another preferred embodiment of the utility model, the difference from embodiment 1 is that a lubricating mechanism is fixed on the box body 1 above the gear 8, the lubricating mechanism includes an oil guide pipe 13, the oil guide pipe 13 penetrates and is connected and fixed on the box body 1, and the oil guide pipe 13 is arranged above the gear 8, a cylinder 11 is fixed on the oil guide pipe 13, the cylinder 11 is fixed on the box body 1 and a piston 12 is slidably inserted, the lubricating oil in the cylinder 11 drips onto the gear 8 through the oil guide pipe 13, and when the gear 8 drives the arc rack 10 to rotate forward and reverse, the lubricating oil is applied to the gear 8 and the arc rack 10, thereby achieving the purpose of lubrication.

[0026] A feed port 14 is provided on the cylinder 11, and a sealing plug 15 is inserted on the feed port 14. The sealing plug 15 is opened, and the lubricating oil can be added to the cylinder 11 through the feed port 14, so that the piston 12 does not need to be withdrawn from the cylinder 11. A baffle 16 is provided on the sealing plug 15, and a rotating shaft 17 is fixed on the baffle 16. The rotating shaft 17 is rotatably arranged on the box body 1. When the piston 12 is pushed to squeeze out the lubricating oil in the cylinder 11, the baffle 16 will block the sealing plug 15, so that the sealing plug 15 will not fall out of the feed port 14 due to the air pressure difference, thereby ensuring that the lubricating oil can be discharged from the cylinder 11 only through the oil guide pipe 13. In addition, rotating the baffle 16 can prevent the baffle 16 from contacting the sealing plug 15. When adding lubricating oil to the cylinder 11 through the feed port 14, the sealing plug 15 can be pulled out from the feed port 14, ensuring smooth addition of the lubricating oil.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
