Description

Technical Field

[0001] The invention relates to the technical field of optical cable manufacturing, and more specifically, to an optical cable loose tube constant temperature cooling device and a cooling method. Background Art

[0002] Loose tube is a tube that can loosely place optical fibers in optical cables to protect them from internal stress and external side pressure. Loose tube is usually made of PBT (polybutylene terephthalate). During the manufacturing process, after PBT is melted and extruded by an extruder at high temperature and cut off, it needs to be cooled by cooling water to allow the molten PBT to cool, crystallize and shrink as expected until it is formed into a loose tube.

[0003] The existing cooling method is: the extruded loose tube passes through a water trough, in which cooling water is stored, and the part of the loose tube in the water trough is completely immersed in the cooling water. The loose tube is fully in contact with the water to achieve the effects of cooling, crystallization and shrinkage, thereby realizing the molding of the loose tube.

[0004] However, since cooling, crystallization and shrinkage are all carried out in the water tank, the loose tube needs to be immersed in cooling water. In order to ensure the cooling effect, a large amount of cooling water is required in the water tank. After the water in the water tank absorbs the heat released by the loose tube, the temperature will continue to rise, especially the water temperature near the loose tube will rise rapidly first, affecting the subsequent crystallization and shrinkage effect; at the same time, after the loose tube is cooled and formed, it needs to be taken out manually from the cooling water, which reduces the work efficiency. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a constant temperature cooling device for an optical cable loose tube, which drives the screw to rotate by controlling the start-up servo motor, thereby driving the retaining member to slide along the guide groove, thereby driving the loose tube to move in the opposite direction of the water flow. During the movement of the retaining member, the guide balls on each group of guide parts slide along the corrugated plate under the elastic force of the reset spring, thereby driving the guide part to move back and forth in the corresponding piston cylinder, so that the high-temperature water after heat exchange near the loose tube is discharged to the rear through the water guide pipe in time, so that during the heat exchange cooling process, a continuous cooling environment is maintained near the loose tube, thereby improving the cooling effect and efficiency.

[0060] A cooling method for an optical cable loose tube constant temperature cooling device comprises the following steps:

[0062] After T2 and PBT are melted and extruded by the extruder at high temperature, they are cut off and fall into the receiving tube 13. The electromagnetic suction cup 33 is controlled to be electrically attracted to the iron plate 34, thereby driving the lifting plate 25 to pull the connecting rope 26 to rise, and then pulling the sliding ring 14 to slide into the arc-shaped sleeve 10, so that the receiving tube 13 drives the loose sleeve to rotate parallel to the ground, preventing the flowing cooling water from impacting the pipe wall for a long time and causing the deformation of the loose sleeve. The cooling water flows along the length direction of the loose sleeve to achieve cooling of the loose sleeve.

[0063] T3. Control and start the servo motor 30 to drive the screw to rotate, thereby driving the retaining member 2 to slide along the guide groove 3, thereby driving the loose tube to move in the opposite direction of the water flow, further improving the cooling effect on the loose tube, so that the loose tube is cooled, crystallized and contracted as expected.

[0064] T4. During the movement of the retaining member 2, the guide balls 51 on each group of guide parts 19 slide along the corrugated plate 16 under the elastic force of the return spring 49, thereby driving the guide part 19 to move back and forth in the corresponding piston cylinder 18, so that the high-temperature water after heat exchange near the loose tube is discharged to the rear through the water pipe 55 in time, so that during the heat exchange cooling process, a continuous cooling environment is maintained near the loose tube, further improving the cooling effect and efficiency.
