Description
Technical Field
The utility model relates to a processing device for longitudinally coating a cable with non-woven fabric.
Background
The armored cable has high compressive strength, strong capability of preventing external force damage and external erosion, and is widely popularized and applied in China. The polyethylene sheath armored cable has good waterproof and cold-resistant performances, so that the polyethylene sheath armored cable is widely applied to waterproof occasions and cold areas in the north of China. However, the environmental stress cracking resistance of polyethylene is not good, so that the anti-cracking performance of polyethylene raw materials, the internal stress release during the extrusion of the polyethylene sheath and the design of the cable structure need to be particularly noticed in the cable processing process, and the polyethylene sheath of the cable is prevented from cracking during construction. The cable armor generally adopts two steel band clearance to wrap the mode, and steel band hardness is big, has great bounce-back trend when wrapping, has aggravated the external tension that the polyethylene sheath bore. When the polyethylene sheath is extruded and processed, the polyethylene sheath is stretched and then coated on the surface of the steel tape armor, the thickness of the polyethylene sheath is uneven due to poor flatness of the surface of the steel tape, the mechanical strength of the position with the thin thickness of the polyethylene sheath is low, and the polyethylene sheath is easy to crack under the action of stress. Therefore, when the polyethylene sheath is processed, proper raw materials, a reasonable die matching and sectional cooling are needed to be selected, a non-woven fabric buffer layer is generally added in the polyethylene sheath, so that the polyethylene sheath is separated from a steel belt, small cracks are not easy to generate on the inner side of the polyethylene sheath, the non-woven fabric buffer layer bears main stress, the polyethylene sheath is prevented from bearing local stress, and the polyethylene sheath is protected.
At present, special processing devices for longitudinally wrapping metal strips such as aluminum-plastic composite strips, steel strips, copper strips, aluminum strips and the like exist in the cable manufacturing and processing process and are widely applied, but the special processing devices for longitudinally wrapping are not suitable for longitudinally wrapping non-metal soft strips such as non-woven fabrics and the like, so that the non-metal soft strips such as the non-woven fabrics and the like basically adopt a wrapping mode at present, time and labor are wasted, and the risk of quality defects generated in the processing process is increased. Such as patent application No. 201020234163.3, publication No. CN 201845600U, and "cable for use in deep cold and ultraviolet region in plateau" are all the same. Therefore, the main reason is that the non-metal soft belt materials such as non-woven fabrics have some problems when being longitudinally wrapped: firstly, the belting rebounds, the non-metal soft belt materials such as non-woven fabrics and the like have larger elasticity, and the non-metal soft belt materials cannot reliably wrap the cable core like the lapping longitudinal wrapping metal belt materials after longitudinally wrapping, so that after the longitudinal wrapping mold is formed, a rebound flattening trend (namely, the belting is formed into a closed tubular state by the forming mold before and returns to a linear state with a U-shaped or even C-shaped or flat cross section) to meet the requirement of longitudinal wrapping) can not be achieved; secondly, the wrapping is incomplete, the non-metal soft belt materials such as non-woven fabrics and the like have larger elasticity, and the non-metal soft belt materials are directly wrinkled during longitudinal wrapping and cannot be longitudinally wrapped into 360 degrees, so that two edges of the wrapping belt which are longitudinally lapped together after the longitudinal wrapping are finished cannot be lapped together; and thirdly, the polyethylene sheath armored cable has a voltage grade related to medium and low voltage cables, and the outer diameter of the cable is generally not less than 20 mm. And the larger the outer diameter of the cable is, the larger the longitudinal wrapping difficulty of the non-woven fabric wrapping tape is.
