Description
Technical Field
The invention relates to the technical field of automatic bundling machine equipment, in particular to a bundling wire knotting prevention device.
Background
An automatic bundling machine is arranged in a collecting area of a production line of a rolling mill to realize automatic bundling of bars with the specification of phi 12-phi 40, wherein a hot-rolled wire coil with the phi 5.5-phi 8mm is used in the bundling line. When the finished bar is conveyed to the bundling machine through the roller way, the gratings on the two sides of the roller way detect the finished bar and automatically bundle the bar. The wire feeding is an important action in the bundling process of the automatic bundling machine, and if the bundling wire is knotted and stuck in the wire feeding process, the wire feeding of the bundling machine is not in place, and the bundling machine breaks down to stop working.
Because the bundling wire coil is unstable in the spinning process in the production process, the wire coil is spun in a large and small time, and is elliptical in a round time, the restraint of the coil collecting barrel is lost in the coil collecting process, a raised coil appears on the surface of the coil collecting, and the phenomena of vertical, horizontal dislocation, staggered layers and cross deflection between coils wound by coils are generated, so that the quality problems of wrong coils, wire disorder, shape deformation and the like of the bundling wire coil are caused. In the in-service use process, because the product of bundling line book is unstable, when the bundling machine send the line, the bundling line does not effectually scatter in proper order but twines together, often causes the bundling line to tie a knot at the horn pipe mouth of bundling machine lead frame and blocks, influences the continuous operation of bundling machine, causes the production to pause.
Disclosure of Invention
The invention aims to provide a device for preventing knotting of a binding wire, which solves the technical problem that the guide pipe opening of a lead frame of a binding machine is knotted and clamped due to the wire binding problems of staggered layers, wire disorder, shape deformation and the like of a coil of a binding wire coil, ensures continuous binding of the binding machine, and reduces the overhauling time and maintenance intensity of the binding machine.
The invention provides a bundling wire knotting prevention device which comprises a guide separation sleeve, wherein the guide separation sleeve is hollow. .
In detail, before the automatic wire feeding of the bundling machine, the bundling wire is passed through the guide separation sleeve with a hollow inner part and enters the bundling machine for bundling through a bundling machine conduit opening. The bundling wire can leave the bundling drum upward movement on one layer at the automatic wire feeding process of the bundling machine, because the gravity of the guide separation sleeve can do the rotating downward sliding movement taking the bundling drum as the circle center along the bundling wire, at the moment, the bundling wire is dispersed under the states of staggered layers, wire disorder and the like under the action of the gravity of the guide separation sleeve and the centrifugal force generated by the rotating downward sliding. In the whole wire feeding process, the bundling wire is upwards rotated and conveyed around the bundling reel, the guide separation sleeve downwards rotates and slides along the bundling wire, the bundling wire is prevented from being wound and knotted before entering the bundling machine, and the condition that the bundling machine stops working due to knotting of the bundling wire at a conduit opening is effectively avoided.
Further, the guide separation sleeve has the mass of 1.0kg-1.8 kg;
preferably, the guide separation sleeve has a mass of 1.2kg-1.5 kg;
preferably, the guide separation sleeve has a mass of 1.2 kg.
In detail, the heavy weight of the guide separation sleeve directly affects the effect of the bundling wire dispersion, when the mass of the guide separation sleeve is lower than 1.0kg, the resultant force of the gravity, the centrifugal force and the supporting force of the guide separation sleeve cannot overcome the friction force, so that the guide separation sleeve cannot rotate down along the coil path of the bundling wire by virtue of the gravity and the centrifugal force, and the effect of the bundling wire coil dispersion is poor; when the mass of the guide separation sleeve is larger than 1.5kg, the bundling wire can be bent due to overlarge mass of the guide separation sleeve, so that the bundling wire coil cannot be dispersed, and on the other hand, the friction force is overlarge due to overlarge pressure of the guide separation sleeve on the bundling wire, so that the guide separation sleeve is difficult to automatically rotate and descend, and the dispersing effect of the bundling wire is poor. Through multiple tests, when the weight of the guide separation sleeve is 1.0kg-1.8kg, the guide separation sleeve can be better suitable for binding wires with the diameter of 5.5-8 mm.
Furthermore, the inner wall of the guide separation sleeve is a cylindrical channel, and the bottom end of the cylindrical channel is connected with a guide section; the guide section is in a circular truncated cone shape, and the upper bottom surface is a wire inlet.
Further, the lower bottom surface of the guide sleeve is communicated with the cylinder channel, and the angle formed by the wire inlet and the cylinder channel is 115-125 degrees;
preferably, the angle is 120 °.
In detail, the bundling wire passes through the wire inlet and the guide section and then penetrates into the guide separation sleeve, in order to enable the guide separation sleeve to disperse the bundling coil with the minimum force, the wire inlet and the cylinder channel are arranged at an angle of 115 degrees and 125 degrees, the contact area of the guide section and the bundling wire is reduced through the adjustment of the angle, so that the friction force between the guide separation sleeve and the bundling wire is reduced, and the guide separation sleeve can slide downwards along the bundling wire more smoothly.
Further, the inner diameter of the cylinder passage is satisfied
ΦInner diameter≥2[ΦBundling wire+r-0.5(4r2-c2)0.5]Formula 1;
wherein the length of the guide separation sleeve is c, and the inner diameter of the cylinder channel is phiInner diameterThe radius of the coil of the binding wire is r, and the diameter of the binding wire is phiBundling wire。
In detail, in order to adapt to binding wires of different sizes and ensure that the guide separation sleeve can freely slide on the binding wire coil, the inner diameter of the cylinder channel and the diameter of the binding wire need to satisfy the formula 1. Namely, the inner diameter of the cylinder channel needs to at least satisfy the sum of the arc length of the corresponding circular arc of the inner diameter of the cylinder channel and the diameter of the bundling wire. If the inner diameter of the cylinder channel is too small, the guide separation sleeve is clamped by the bundling wire when sliding downwards, and cannot slide downwards, so that the dispersion effect is influenced.
Further, the inner wall of the cylinder channel is made of polytetrafluoroethylene or other coating materials with small friction coefficients.
In detail, polytetrafluoroethylene is a high molecular polymer prepared by polymerizing tetrafluoroethylene as a monomer, has an extremely low friction coefficient, and in order to enable the guide separation sleeve to slide on the bundling wire more smoothly, polytetrafluoroethylene or other coating materials with a small friction coefficient are coated on the inner wall of a cylinder channel, so that the friction force of the bundling wire in the guide separation sleeve is reduced, the movement of the guide separation sleeve on the bundling wire is smoother, and the disordered bundling wire coil is easier to be dispersed.
Furthermore, the guide separation sleeve also comprises a bearing fixed inside the tail end of the guide separation sleeve and communicated with the top end of the cylinder channel.
In detail, the top end of the cylinder channel is provided with a bearing fixed by a clamp spring, and the bearing is used for reducing the friction force of the bearing in the movement process, so that the movement of the bundling wire in the guide separation sleeve is smoother.
Further, the guide separation sleeve is provided with a protruding platform and a tooth groove, and the protruding platform is connected with the tooth groove.
Further, the tooth sockets are at an angle of 70-100 °;
preferably, the gullets are at an angle of 90 °.
Furthermore, the two ends of the protruding platform and the tooth groove are respectively provided with a seam allowance for dispersing bundling wires.
In detail, the tooth socket and the seam allowance are arranged on the outer layer of the guide separation sleeve and used for scattering the wound bundling wire coil under the impact action generated when the guide separation sleeve slides downwards along the bundling wire.
Compared with the prior art, the invention has the following technical effects:

In examples 1 to 3, the cylindrical passage diameter phiInner diameterNot less than the value of the formula 1, the guide separation sleeve 1-1 can smoothly slide on the binding wire 2-2 at this time, and the deformation of the binding wire 2-2 does not occur, whereas in the embodiment 4-5, the diameter phi of the cylindrical passage isInner diameterThe value of the formula 1 is less than, in the process of conveying the bundling wire 2-2, the guide separation sleeve 1-1 is clamped at the deformed position of the bundling wire 2-2 due to the deformation of the bundling wire 2-2, and the rotation and the sliding are difficult.
Thus, the diameter phi of the cylindrical passageInner diameterDiameter phi of binding wireBundling wireWhen the relation between the guide separation sleeve and the binding wire meets the formula 1, the guide separation sleeve 1-1 can smoothly rotate and slide down on the binding wire 2-2, and the binding wire 2-2 is not deformed.
