Technical Field
The invention relates to the technical field of cable production equipment, in particular to tensioning equipment for manufacturing ethylene-propylene insulating flame-retardant control cables.
Background
The control cable is a polyvinyl chloride insulation and polyvinyl chloride sheath control cable suitable for industrial and mining enterprises, energy traffic departments, occasions for controlling and protecting lines with the alternating current rated voltage of below 450/750 volts, and the like. Along with the higher performance requirement of application places, a novel control cable is generated, namely the ethylene-propylene insulating flame-retardant control cable has higher insulating performance and flame-retardant property, so that the requirements on production and processing are stricter. During processing, need install the rubber sleeve with stranded sinle silk, but, because the error in the assembling process is difficult to eliminate, the rubber sleeve is inseparable with the cooperation of sinle silk, leads to the sinle silk to corrugate easily in the rubber sleeve, causes the insulating fire-retardant control cable product quality of EP rubbers unqualified, and product defective rate greatly increased is unfavorable for the economic benefits growth of enterprise. Therefore, the tensioning device for manufacturing the ethylene-propylene insulated flame-retardant control cable is urgently needed.

The invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a front view of the present invention;
fig. 2 is a top view of the present invention.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.
As shown in fig. 1 to 2, a tensioning device for manufacturing ethylene-propylene insulated flame-retardant control cable comprises: a frame 1; the two pressing mechanisms 2 are symmetrically arranged on the left side and the right side of the rack 1, each pressing mechanism 2 comprises a V-shaped swing rod 21 which is pivotally arranged on the front side of the rack 1, one end of each V-shaped swing rod 21 is positioned above the rack 1 and is fixedly provided with a pressing roller 22, and the other end of each V-shaped swing rod 21 is positioned below the rack 1 and is provided with a driving column 23; the two conveyer belt mechanisms 3 are arranged corresponding to the two pressing rollers 22, each conveyer belt mechanism 3 comprises a plurality of rollers 31 which are sequentially close to each other and can pivot, and a conveyer belt 32 is matched on each roller 31; and the driving mechanism 4 comprises a lifting piece 41 and a moving plate 42 connected with the lifting piece 41, and the driving columns 23 of the two pressing mechanisms 2 are connected with the moving plate 42 in a sliding manner along the length direction of the moving plate 42.
In some embodiments, the pressing mechanism 2 further comprises a support roller 24 pivotably disposed on the V-shaped swing link 21, the support roller 24 being located above the frame 1 and adjacent to the driving column 23.
In some embodiments, the moving plate 42 is provided with an upper sliding groove 42a, and the driving posts 23 are all fitted on the sliding groove 42 a.
In some embodiments, the lifting member 41 is any one of a cylinder, a hydraulic cylinder, and an electric push rod.
The method of use of the invention is described below:
when the cable tensioning device is used, a cable is placed on the two conveyor belt mechanisms 3, the lifting piece 41 is started, the extension rod of the lifting piece 41 extends out to drive the moving plate 42 to lift upwards, the moving plate 42 pushes the driving column 23 to move upwards, the driving column 23 can slide in the sliding groove 42a, so that the left V-shaped swing rod 21 rotates anticlockwise, the right V-shaped swing rod 21 rotates clockwise, the two supporting rollers 24 support the lower side of the cable, the two pressing rollers 22 press the cable onto the conveyor belt 32, and the pressing rollers 22 are fixed and cannot rotate, so that the two pressing rollers 22 have horizontal component forces in opposite directions on the cable to drive the cable to move on the roller 31 for a distance along with the conveyor belt 32, and therefore the two ends of the cable are tensioned.
In conclusion, the invention can realize the stretching and tensioning of the two ends of the cable, and simultaneously can avoid the middle part of the cable from drooping in the tensioning process, thereby ensuring better tensioning effect. The whole device has the advantages of simple structure, convenient use, simple operation and strong reliability.
