Description

Technical Field

[0001] The present invention relates to the technical field of cable manufacturing, and in particular to a device for online detection of rip cord breakage. The present invention also provides a detection method for online detection of rip cord breakage. Background Art

[0002] The country's infrastructure construction in various fields has been rapidly developed. As the central nervous system of signal transmission, data cables are increasingly widely used in various fields. Data cables are usually composed of cable cores, cross skeletons, tear cords, and insulating polyethylene sheaths wrapped around the cable cores. The tear cords play two roles: one is to strengthen the overall tensile strength of the data cable and act as a reinforcing rib; the other is to facilitate breaking the outer skin of the data cable.

[0003] However, in the production process of data cables, the phenomenon of broken rip cords often occurs, which seriously affects the quality and safety of the data cables. In addition, since the equipment does not automatically shut down after the rip cord breaks, it is difficult to locate the breaking point of the rip cord after it is assembled into the data cable. Therefore, it is difficult to repair during the rework process, which greatly increases the production cost of the cable. Summary of the invention

[0004] In response to the above problems, the present invention provides a device for online detection of tear rope breakage, which is preset at the front end of the material feeding of the data cable production line. When the tear rope breakage is detected, an alarm is directly issued, thereby preventing the broken tear rope from being mixed into the data cable, thereby reducing the cable repair cost.

When the tear rope breaks, the outer roller swings downward due to gravity until the metal rod presses the upper convex telescopic rod downward to the low point, and the travel switch is turned on. After the controller receives the signal of the travel switch, it drives the alarm to sound an alarm and drives the power supply end of the data cable production line to cut off the power.

[0019] After adopting the structure of the present invention, during the online production process, the tear rope is continuously transported to the data cable production line. After the tear rope breaks, the outer roller swings downward.

The alarm is preset at the front end of the feed of the data cable production line. When the tear rope break is detected, an alarm is directly issued, thereby avoiding the broken tear rope from being mixed into the data cable, reducing the repair cost of the cable.

[0027] The pressing roller assembly 30 includes a connecting shaft 31 and an outer roller 32;

[0028] The travel switch 40 includes a base 41 and an upwardly convex telescopic rod 42. When the upwardly convex telescopic rod 42 is pressed to a low point by an external force, the travel switch 40 is turned on.

[0029] The controller 50 is integrated with an alarm;

[0030] The mounting rod 21 is inserted into the first positioning hole 11 of the mounting vertical plate 10. The first positioning hole 11 is provided with a first bearing 60. The mounting rod 21 is inserted into the inner ring of the first bearing 60. The mounting rod 21 is reliably rotatable.

[0031] A second positioning hole 23 is provided at one end of the swing lever 22 away from the mounting lever 21. The connecting shaft 31 includes an inner end connecting flange 311 and a shaft body 312. The shaft body 312 penetrates through the second positioning hole 23 and then protrudes outward. The inner end connecting flange 312 is fastened to the corresponding ring cloth connecting hole of the swing lever 22 by screws. The outer end of the connecting shaft 31 protrudes outward and is sleeved with a second bearing 70. The outer roller 32 is sleeved on the outer ring of the third shaft 70, which ensures the reliable rotation of the outer roller.

[0032] The outer roller 32 protrudes outward from the front facade of the mounting plate 10, and the outer roller 32 protrudes forward from the swing rod 22. In the working state, the roller surface of the outer roller 32 is used to press the tear rope 80 that passes in a straight line. A metal pressure rod 24 is also integrated on the swing rod 22. The mounting plate 10 is fixed with a travel switch 40 at a position directly below the metal pressure rod 24 when it rotates to a horizontal state. The upper convex telescopic rod 42 of the travel switch 40 is set upward. When the metal pressure rod 24 rotates to the horizontal state area, the upper convex telescopic rod 42 is pressed. The travel switch 40 is connected to the controller 50 through a wire 90. After the controller 50 receives the signal of the travel switch 40, it drives the alarm to sound. The controller 50 is also externally connected to the power supply end of the data cable production line. After the controller 50 receives the signal of the travel switch 40, it drives the power supply end of the data cable production line to cut off the power.

[0033] In a specific embodiment:

[0034] An inner concave guide ring groove 321 is provided in the middle of the axial length direction of the outer ring surface of the outer roller 32, and the guide ring groove 321 is used to pass the tear rope 80 to ensure that the tear rope 80 does not separate from the outer roller 32;

[0035] The width of the guide ring groove 321 is greater than the diameter of the tear rope 80 , and the depth of the guide ring groove 321 is not less than half of the diameter of the tear rope 80 .

[0036] In a specific embodiment, a protruding mounting seat 12 is provided at a position of the mounting plate 10 corresponding to the base 41 of the travel switch 40 , and the base 41 is fixedly mounted on the protruding mounting seat 12 , ensuring that the installation of the travel switch 40 is simple and reliable.

[0037] A method for online detection of tear rope breakage: an online tear rope breakage detection device is arranged in front of the tear rope loading position of the data cable production line, the tear rope passes through the lower supporting point of the outer roller in a straight direction, the tear rope supporting outer roller is arranged at the upper position of the travel switch, when the tear rope breaks, the outer roller swings downward due to gravity until the metal rod presses the upper convex telescopic rod downward to the low point, the travel switch is turned on, and after the controller receives the signal from the travel switch, it drives the alarm to sound and drives the power supply end of the data cable production line to cut off the power.

[0038] Its working principle is as follows: During the online production process, the tear rope is continuously transported to the data cable production line. After the tear rope breaks, the outer roller swings downward. When the outer roller reaches the lowest point, the metal rod connected to it pushes the convex telescopic rod of the travel switch to make the internal contacts of the travel switch close to realize circuit conduction, thereby sending a shutdown alarm of the tear rope break to the controller. It is preset at the front end of the feed of the data cable production line. When the tear rope break is detected, an alarm is directly issued, thereby avoiding the broken tear rope from being mixed into the data cable, reducing the cable repair cost.
