Abstract

The utility model relates to a wire take-up tension control automatic system which is matched with a knitting machine used for making a cable shielding layer. According to the technical problem to be solved, the provided system should be capable of automatically adjusting the tension of a core wire, so as to improve the quality of a cable. According to the technical scheme, the knitting machine wire take-up tension control automatic system comprises a wire take-up and pay-off stand, a wire take-up reel arranged on the wire take-up and pay-off stand, a motor which is used for driving the wire take-up reel to rotate and is provided with a gear box, and a controller. The knitting machine wire take-up tension control automatic system is characterized in that the system further comprises a magnetic powder brake device which is arranged between the gear box and a spindle of the wire take-up reel and a pressure sensor arranged at the top of the knitting machine; and the controller switches into conduction with the pressure sensor and the magnetic powder brake device respectively through a data line. The pressure sensor is arranged below a guide wheel seat at the top of the knitting machine.

Description

Braiding machine takeup tension control automatic system
Technical field
The utility model relates to a kind of Tension Control automatic system, especially makes the matched takeup tension control of the braiding machine automatic system of cable shield.
Background technology
The screen of coaxial cable adds wire braid by aluminium foil layer usually and forms.At present, the manufacturing machine of cable metal silk braid often is 16 ingots, 24 ingot high-speed knitters.General heart yearn (being that inner wire adds insulating barrier) external diameter is chosen on the 16 ingot high-speed knitters at the coaxial cable below the 7mm to be processed, and core line diameter then will arrive 24 ingots even bigger braiding machine production greater than the coaxial cable of 7mm.For the coaxial cable of core line diameter greater than 7mm, because folding and unfolding drum big (general diameter is 1250mm), so the take-up and pay-off device that can not carry with braiding machine, draw drum and take-up reel all must be installed on the independent folding and unfolding coil holder and carry out.But, because the tension control system of traditional folding and unfolding coil holder comparatively simple (torque motor control model), takeup tension not can along with the take-up amount what and change, necessarily require the operative employee to remove to adjust takeup tension termly.Therefore, improper or untimely through regular meeting owing to the operative employee regulates, cause heart yearn excessive by drawing-down, thereby cause cable performance defective because of moment.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes the above-mentioned background technology, and a kind of braiding machine takeup tension control automatic system is provided, and this system should have the function that can regulate heart yearn tension force automatically, to improve cable quality.
The technical scheme that the utility model adopts is: braiding machine takeup tension control automatic system comprises the folding and unfolding coil holder, is installed in the take-up reel on the folding and unfolding coil holder, a motor that has reduction box and the controller that the driving take-up reel rotates; It is characterized in that this system also comprises the pressure sensor that is installed in the magnetic brake apparatus between reduction box and the take-up reel rotating shaft and is installed in the braiding machine top, described controller is respectively through data wire and pressure sensor and the conducting of magnetic brake apparatus.
Said pressure sensor is installed under the wheel stand at braiding machine top.
The operation principle of the utility model is: behind the electric motor starting; Power is delivered to the power shaft of reduction box through V belt; After reduction box slows down, be delivered to the magnetic brake apparatus, the magnetic brake apparatus will be regulated transmission of torque again automatically to the take-up reel rotating shaft, and then drive the take-up reel take-up; The pressure sensor 8 that is installed on simultaneously under the wheel stand of braiding machine top is being monitored the variation of pressure in real time, and sends signal and come real-time regulated output torque size for magnetic brake apparatus 7; Finally, realize the automatic control of braiding machine takeup tension.
The beneficial effect of the utility model is: the takeup tension control automatic system that the utility model provides, can guarantee the stable of output torque, and solved existing apparatus effectively because takeup tension is unstable, cause heart yearn to be drawn little defective; And the utility model can control suitable output tension force automatically according to heart yearn line footpath size, guarantees that on-line tension is at setting range.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A portion structure for amplifying sketch map among Fig. 1.
Embodiment
As shown in Figure 1, the motor 6 that has reduction box drives take-up reel 5 and rotates; 1 unwrapping wire position that is installed on folding and unfolding coil holder 10 through with lock minor axis of shaftless of draw drum of heart yearn is housed; Heart yearn 2 is pulled out from draw drum passively, gets into the line-entering hole of braiding machine 4.Its braiding process the same with traditional knit operation (aluminium foil evenly, closely is coated on the heart yearn surface through the aluminium foil frame, and braiding is superimposed upon aluminium foil surface equably) behind the heart yearn entering braiding machine.Accomplish the processing line 2-1 (promptly the surface has the heart yearn of wire sheathing) that weaves, the guide wheel 3 at braiding machine top is taken turns, is installed on to the large traction in braiding, gets back to take-up reel.Said structure is all identical with existing take-up and pay-off device.
The improvement of the utility model is: between reduction box (among the figure, reduction box is blocked by the magnetic brake apparatus) and the take-up reel rotating shaft magnetic brake apparatus 7 has been installed; At (under the wheel stand 3-1) under the guide wheel at braiding machine top pressure sensor 8 (preferred STS-030 differential pick-up) has been installed again; Act as and detect the pressure that litzendraht wire imposes on guide wheel in real time, and pressure is converted into signal of telecommunication transmission (sending through data wire 8-1) to controller (being installed in the control cabinet 9); Controller is controlled the magnetic brake apparatus again, thereby reaches the on-line tension purpose of control automatically.
All components and parts in the utility model and the equal buyable of material.
