Description

Technical Field

[0001] The utility model relates to a wire pay-off device, specifically, a wire pay-off device for paying out unextruded wire from a wire drum and sending the unextruded wire to the next process, namely, an extruder for extrusion. Background Art

[0002] It's well known in the wire manufacturing industry that during the production process, unextruded wire must be unwound from a reel and fed to an extruder for extrusion. Currently, the devices used to unwound the unextruded wire from the reel and feed it to the extruder are all traditional pay-off devices. These traditional pay-off devices consist of a base, a reel, a motor, and a controller. One side of the base has a shaft seat, and a spindle is mounted on the base inside the shaft seat. The front and rear sections of the spindle are tapered and cylindrical, respectively. The reel is coaxial with the spindle, with a baffle at its outer end flush with the outer end of the spindle's cylindrical section. A guide plate is attached to the outer surface of the baffle at its inner end. The motor is located outside the shaft seat, and its output shaft rotatably passes through the shaft seat and connects to the center of the baffle at the adjacent end of the reel. During operation, as the motor drives the reel to rotate, the outer ends of the unextruded wire on the reel pass sequentially between the guide plate and the spindle, then exit through the outer end of the tapered section at the front of the spindle, feeding it to the extruder for extrusion. Although this pay-off device can release unextruded wire from the reel, the reel will rotate slowly over time, causing the pay-off position to shift, changing the reserved length of the wire end at the inner end of the previous reel. As a result, after the wire on the previous reel is released, the wire end at its inner end welds to the outer end of the wire on the next reel, causing pulling and jerking, resulting in wavy wires after being extruded by the extruder, and poor product quality. Utility Model Content

[0003] The problem to be solved by the utility model is to provide a wire pay-off device for wire production, which can improve the product quality of the wire.

[0004] The above-mentioned problem to be solved by the present invention is achieved by the following technical solutions:

[0005] The utility model discloses a wire-paying device for producing electric wires, comprising a base, a wire drum, a motor, and a controller. One side of the base has an axle seat, and a spin drum is mounted on the base inside the axle seat. The front and rear sections of the spin drum are conical and cylindrical, respectively. The wire drum is coaxial with the spin drum, and the outer side surface of the baffle at its outer end is flush with the outer end of the spin drum's cylindrical section. The outer side surface of the baffle at its inner end is connected to a guide circular plate. The motor is located outside the axle seat, and its output shaft rotatably passes through the axle seat and is connected to the center of the baffle at the adjacent end of the wire drum. The device is characterized in that a pin seat is provided on the upper side of the outer end of the cylindrical section of the spin drum, and radial ribs are distributed circumferentially on the outer side surface of the baffle at the outer end of the wire drum. A clip strip is provided between the pin seat and the outer side surface of the baffle at the outer end of the wire drum. The clip strip is rectangular, its width matching the width between adjacent radial ribs, its upper end is hinged to the pin seat, and its lower end is engaged between a pair of adjacent radial ribs during operation.

[0006] The inner diameter of the cylindrical section of the spinning drum is larger than the diameter of the guide circular plate. The outer end of the wire on the wire drum passes between the guide circular plate and the spinning drum and then passes through the outer end of the tapered section of the front section of the spinning drum.

[0007] It can be seen from the above technical solution that since the utility model has a pin seat on the upper side of the outer end of the cylindrical section of the spinning drum, the outer side surface of the baffle at the outer end of the wire drum is evenly distributed with radial ribs in the circumferential direction, and there is a card strip between the pin seat and the outer side surface of the baffle at the outer end of the wire drum. The card strip is rectangular, and its width is adapted to the width between adjacent radial ribs. There is a pin seat on the upper side of the outer end of the cylindrical section of the spinning drum, and the upper end of the card strip is hinged on the pin seat, and its lower end is stuck between a pair of adjacent radial ribs during operation. The card strip can prevent the wire drum from rotating slowly, avoid the displacement of the wire-releasing position, and ensure that the reserved length of the wire head at the inner end of the previous wire drum will not change. In this way, after the wire on the current wire drum is released, the wire head at its inner end will be welded to the outer end of the wire on the next wire drum without pulling or stalling, thereby avoiding the occurrence of wavy heads in the wire after extrusion by the extruder, greatly improving product quality.
