Detailed Description

As shown in fig. 1, a tow opening device in a rod making machine includes: the device comprises a frame 1, a rubber smooth roller 2 and two roller iron rollers 3 are arranged on the frame 1, the rubber smooth roller 2 and the two roller iron rollers 3 are arranged in a delta shape, the two roller iron rollers 3 are positioned below the rubber smooth roller 2, one roller iron roller 3 is a driving roller driven by a motor, the driving roller iron roller 3 drives the other roller iron roller 3 to rotate through a transmission chain 4, the rubber smooth roller 2 is driven to lift by two cylinders 6, the rubber smooth roller 2 can press tows 9 on the two roller iron rollers 3 after descending, so that the tows 9 can be stretched and opened when being clamped by the three rollers to convey forwards, two ends of the rubber smooth roller 2 are respectively arranged on the middle part of one swing rod 5 through bearings, the front ends of the two swing rods 5 are respectively hinged with the frame 1, the rear ends of the two swing rods 5 are respectively hinged with a connecting block 51, the two cylinders 6 are respectively positioned below the two connecting blocks 51 one by one, the cylinder bodies of the two cylinders 6 are respectively hinged with the frame 1, the two connecting blocks 51 are respectively fixed with the piston rods of the corresponding cylinders 6 through a screw 7, so that the two cylinders 6 can drive the rubber smooth rollers 2 to lift by driving the two swing rods 5 to swing up and down, the two screw 7 are respectively in threaded connection with a pressing block 8 with adjustable height, a travel switch 81 fixed with the frame 1 is respectively arranged below the two pressing blocks 8, a trigger rod 82 is respectively arranged between the two travel switches 81 and the corresponding pressing block 8, the middle parts of the two trigger rods 82 are respectively hinged with the frame 1, the hinged parts of the two trigger rods 82 are respectively provided with a torsion spring which can twist the trigger rod 82 to ensure that the lower end of the trigger rod 82 can press and trigger the corresponding travel switch 81, the two pressing blocks 8 can press the upper ends of the corresponding trigger rods 82 when the two cylinders 6 drive the rubber smooth rollers 2 to descend to open the tows 9 after the height of the two pressing blocks 8 is adjusted, so that the lower ends of the two trigger rods 82 can tilt upwards without pressing the travel switch 81 corresponding to the trigger, and the travel switch 81 is in communication connection with the controller of the rod making machine. When the tows are wound too much, the rubber smooth roller 2 can be jacked up by the wound tows, so that the pressing block 8 does not press the upper end of the trigger rod 82 due to rising, the trigger rod 82 presses the corresponding travel switch 81 downwards under the action of the torsion spring, when any one of the two travel switches 81 is triggered, the controller of the slivering machine stops the slivering machine, a worker finds that the slivering machine can be cleaned after stopping, the worker does not need to pay attention to the slivering machine all the time, the worker can be liberated, and the working efficiency of the worker is greatly improved.

In the present embodiment, a combining cap 83 capable of tightly combining the pressing block 8 by abutting against the pressing block 8 is further screwed to each of the two screws 7.

In addition, a protective cover 84 is arranged on the outer side of the transmission chain 4, a proximity sensor 85 which can be triggered by the transmission chain 4 is arranged on the upper portion of the protective cover 84, when the transmission chain 4 is broken and falls, the proximity sensor 85 is not triggered by the transmission chain 4, and the proximity sensor 85 is in communication connection with a controller of the strip making machine. If the drive chain 4 breaks, the three rollers cannot rotate synchronously, so that the opening and stretching effect cannot be achieved, and therefore when the drive chain 4 breaks and the proximity sensor 85 is not triggered, the controller of the plodder can stop the plodder, and then a worker replaces the new drive chain. The trigger lever 82 is formed by sequentially connecting an upper vertical rod 821, a middle cross rod 822 and a lower vertical rod 823, and a hinge point of the trigger lever 82 is arranged on the middle cross rod 822, so that the trigger lever 82 can be better adapted to the layout of equipment.
