Problems solved by technology

In the prior art, the thermal difference method is usually used to control the excess length of the loose tube, but the PP material has a strong post-shrinkage, and it will continue to shrink within 48 hours after the loose tube of the optical cable is cooled, so the thermal difference method cannot be applied Due to the loose tube of PP material, the excess length of the loose tube of PP material is still uncontrollable, which affects the transmission performance of the optical fiber

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0030] See Figure 1 to Figure 3 As shown, the embodiment of the present invention provides a squeezing and pulling device for a loose tube of an optical cable, which includes a frame 1 and an extrusion mechanism 2 provided on the frame 1.

[0031] The extrusion mechanism 2 includes two sets of clamping wheels 20 and a driving mechanism 21 arranged in parallel. The clamping wheel set 20 is arranged on the frame body 1. The clamping wheel set 20 includes at least two rollers 200 and a traction belt 201 that cooperates with the two rollers 200. A traction belt 201 is formed between the two traction belts. In the channel 202 of the loose tube of the optical cable, the driving mechanism 21 is connected to the roller 200 and drives the roller 200 to rotate.

[0032] The squeezing mechanism 2 also includes a pressure mechanism 22, which is used to bend both sides of ...

Abstract

The invention discloses an extruding and pulling device for cable loose tubes and relates to the field of cable manufacturing. The extruding and pulling device for the cable loose tubes comprises a rack and an extruding mechanism arranged on the rack. The extruding mechanism comprises two clamping wheel sets arranged in parallel and a drive mechanism, wherein the clamping wheel sets are arranged on the rack. Each clamping wheel set comprises at least two rollers and a pulling belt matched with the two rollers. A channel for extruding and pulling the cable loose tubes is formed between the two pulling belts. The drive mechanism is connected with the rollers and used for driving the rollers to rotate. The extruding and pulling device for the cable loose tubes can effectively control the excess lengths of the cable loose tubes and is simple in structure and wide in application range.

Description

Technical field [0001] The invention relates to the field of optical cable manufacturing, in particular to an squeezing and pulling device for a loose tube of an optical cable. Background technique [0002] PP is a kind of raw material for the production of loose tube of optical cable. Compared with traditional PBT and other materials, PP material has better tensile and bending properties, which can meet the bending of loose tube in a narrow space, so the loose tube of PP material The application of casing is more and more extensive. [0003] Since the loose tube has strong shrinkage, it is necessary to control the shrinkage of the loose tube within a smaller range. In the prior art, the thermal difference method is usually used to control the excess length of the loose tube, and the PP material has strong post-shrinkage, and it will continue to shrink within 48 hours after the loose tube of the optical cable is cooled. The thermal difference method is not applicable Because of t...
