Description

a twisting machine

technical field

The invention relates to the thread processing industry, textile machinery, especially twisting machines.

Background technique

Existing thread processing industry, textile machinery, twisting machine are in use, and two or more silks are twisted into a thread through the effect of twisting machine with more than two silks. In actual work, sometimes one of the twisted yarns will be broken, and the unbroken yarn will continue to be twisted, but the twisted yarn with few yarns does not meet the product requirements; On the shaft or pressure roller, if the operator does not find the silk in time, he will continue to wind, and the continuous winding of the silk will only waste the silk, which will reduce the output, increase the rework rate, and increase the cost; the operator must often check each spindle and machine, and the labor intensity is relatively high. Big.

Contents of the invention

The task of the present invention is to provide a switch, a wire breaking device and a wire breaking and winding display device capable of detecting broken wire signals and wire winding signals. When the twisted yarn is cut off quickly, the twisting state of the few yarns will be stopped immediately, and a broken yarn signal will be sent to the operator; when the twisted yarn is wound on the roller shaft or the pressure roller, the yarn will be cut off, and the winding status will be stopped immediately, and Send out winding signal for the operator; the signal light is set at the position of the broken wire and is convenient for installation and observation, so that the operator can eliminate the fault in time when he observes the signal light, and reduces the labor intensity of the operator.

In order to solve the above tasks, the solution adopted by the present invention is: the existing twisting machine has a frame, an electrical appliance, a twisting volume, and a forming mechanism, and it is characterized in that: a broken wire switch is added, and a wire guide hook is fixed on the broken wire switch , the broken wire switch is fixed on the hanger of the twisting machine with bolts. When there is a broken wire, the broken wire switch works, and the electricity is used to control the work of the broken wire device so that the unbroken wires are quickly cut off, and the twisted state of the few wires is immediately stop, and send a signal for the operator to break the wire; there is a wire winding switch, and the wire winding switch is fixed on the left and right of the pressure roller bracket; there is a wire breaking device, which is installed on the wire paralleling device bracket. The wire breaking device consists of a wire device, an electromagnet, and a cutting knife. When the twisted wire is wound on the roller shaft or the rubber pressure roller, the wire breaking device works so that the working state of the winding wire is immediately stopped; there are wire breaking and winding signals. The display light is shared by the broken wire and the wound wire, connected to the power supply and the wire, which are respectively controlled by the broken wire switch and the wound wire switch. The display light is set at the broken wire position for easy installation and observation, and the operator can see the display Lights can be removed in time to troubleshoot.

Broken wire switch: guide wire hooks are welded on the left and right sides of the bottom plate, and the inner side of the guide wire hook must satisfy the swing rod to move freely; There is an insulating plate installed between the fixed contact and the bottom plate, and the switch line A and switch line B swing rod is integrated with the arm lever and the moving contact. Correspondingly, one set has a counterweight welded on the side of the round hole. During operation, the silk thread enters the notch of the guide wire hook and slides down. The silk thread moves the swing lever to rotate, and the moving contact is separated from the fixed contact. When line B is disconnected, the broken wire switch is in the closed state; when there is a broken wire, otherwise the wire is turned on, and the broken wire switch is in the open state at this time, which can control the action of the electromagnet.

Wire winding switch: There is a shaft on the bottom plate of the wire winding switch, and an insulating seat, a fixed contact, and a spring are installed. The switch bottom plate is connected to the left and right sides of the gap of the pressure roller bracket with adjusting screws. The screw is fixed on the pressure roller bracket, and the switch bottom plate can move a certain distance up and down with the adjustment screw in the gap of the pressure roller bracket. The nylon block is placed in the U-shaped groove of the pressure roller bracket to limit the movement range of the pressure roller shaft. The rotating arm is installed on the shaft. When the roller shaft is wrapped with wire or the roller shaft is wrapped with wire, the roller shaft moves up and down, and the bearing is rotated by the action of the spring to drive the moving contact to rotate and contact with the fixed contact to make the switch line B and the switch The conduction of the line A achieves the open state of the switch, and plays the function of controlling the action of the electromagnet.

Wire breaking device: Installed on the original wire paralleling device bracket, they are composed of a supporting plate, a wire paralleling device, an electromagnet, a slider, a cutting knife, screws, and a connecting plate. The mutual installation positions are shown in Figure 5. The cutting knife is circular, and there is a hole in the center of the circle for installation, and there are N evenly distributed holes on the circle for when one cutting edge cannot be used, use a hook to go down through the cutting knife through the circular arc groove in Figure 7 There is an evenly distributed hole on the circle and pull back to make the cutting knife rotate a distance to achieve the purpose of changing the cutting edge; the cutting knife is placed on the lower plane of the wire doubling device, and there is a working distance between the cutting knife edge and the silk thread. When the switch is turned on, the electromagnet is energized, and the electromagnet iron core drives 35 connecting plates to drive the cutting knife to move forward and cut off the wire.

The signal display lamp is composed of a broken wire display lamp and a wire winding display lamp, connected to a power supply and a wire, and they are respectively controlled by a broken wire switch and a wire winding switch. The display light is set at the broken wire position and is convenient for installation and observation.

When operating, slide the wire from the notch of the guide wire hook and slide down, the wire moves the swing lever to rotate, the moving contact is separated from the fixed contact, the switch line A and switch line B are disconnected, that is, the broken wire switch is closed, and the electromagnet is not Power on, cutting knife, broken, thread entangled indicator lights are not working; during work, when a wire is broken, the pendulum loses resistance, under the gravity of the arm lever or counterweight, the moving contact and the fixed contact conduct, that is, the wire is broken. The switch is in the open state, the electromagnet is energized, the cutting knife works to cut off the wire, and the broken wire indicator light works; in another case: when the twisted wire is wound on the roller shaft or the rubber pressure roller, the rubber pressure roller moves up to make The wire winding switch is turned on to energize the electromagnet, and the push rod drives the cutting knife to move forward to cut off the wire, and at the same time, the wire winding display lamp works.

Due to the use of the above solutions, sometimes one of the twisted yarns will be broken, and the unbroken yarn will be cut off immediately, preventing the monofilament from continuing to twist; when the twisted yarn is wound on the roller shaft or rubber pressure roller, the broken yarn The device cuts off the wire, and sends a signal for the operator to break and wrap the wire; the signal indicator light for the broken wire and the wire wrap is set at the position of the broken wire, which is convenient for installation and observation, and is convenient for the operator to observe. Raw materials, increased output, and easy operation.
