Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle production, and particularly relates to a wire drawing device for plastic particle production. Background Technique

[0002] ABS engineering plastics, namely PC+ABS (engineering plastic alloy), are called plastic alloy in the chemical industry. The reason for naming it PC+ABS is that this material not only has the excellent heat resistance, weather resistance, dimensional stability and impact resistance of PC resin, but also has the excellent processing fluidity of ABS resin.

[0003] In the process of PC / ABS plastic particle production, wire drawing equipment is usually required. The wire drawing equipment is mainly used to stretch the molten plastic into thin filaments through a wire drawing die, and the thin filaments are subsequently cut into particles of a certain length by cutting equipment. The wire drawing equipment generally includes a winding mechanism, a guiding mechanism, a temperature control system and other auxiliary systems. When the existing wire drawing equipment uses a wire drawing clamp for guiding and winding, the conveying position of the wire drawing clamp is fixed, which may cause the winding mechanism to be wound around each other during winding. Therefore, there are certain limitations.

[0004] Therefore, we urgently need to provide a wire drawing device for plastic particle production. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wire drawing device for plastic particle production, so as to solve the problem that when the existing wire drawing equipment uses a wire drawing clamp for guiding and winding, its conveying position is fixed, which may cause the winding mechanism to be wound around each other during winding as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A wire drawing device for plastic particle production, applicable to the production of PC / ABS plastic particles, includes a bottom plate, a positioning wire feeding device and a winding device, and the positioning wire feeding device and the winding device are respectively installed on the left and right sides of the upper surface of the bottom plate.

[0007] The positioning wire feeding device includes a transverse movement unit and a positioning wire threading unit.

[0008] The transverse movement unit includes a driving motor, a bearing seat, a reciprocating lead screw and a threaded sliding table. The driving motor is installed at the front end of the left side of the upper surface of the bottom plate, and the two bearing seats are respectively installed at the front and rear ends of the left side of the upper surface of the bottom plate. The reciprocating lead screw is connected to the output end of the driving motor and is rotatably connected to the inside of the bearing seat. The threaded sliding table is threadedly connected to the reciprocating lead screw.

[0009] A further improvement lies in that a guiding chute is provided on the left side of the upper surface of the bottom plate. A slider is fixedly connected to the bottom of the threaded sliding table, and the slider is slidably connected to the inner wall of the guiding chute. When the winding device winds the plastic wire material, the driving motor is started to drive the reciprocating screw rod to rotate inside the bearing seat, thereby driving the threaded sliding table on the reciprocating screw rod and the slider at its bottom to slide along the guiding chute, so as to move more stably. At this time, the positioning wire threading unit at its top also moves accordingly, so that the wire is evenly wound on the winding device, avoiding the situation that the wires are wound and knotted with each other.

[0010] A further improvement lies in that the positioning wire threading unit includes a wire threading cylinder, an electromagnetic ring, and a wire feeding assembly. The wire threading cylinder is fixedly connected to the top of the threaded sliding table. The electromagnetic ring is installed on the inner wall of the wire threading cylinder. Four groups of the wire feeding assemblies are fixedly connected to the inner wall of the electromagnetic ring in a ring shape.

[0011] A further improvement lies in that the wire feeding assembly includes a guiding sliding sleeve, a permanent magnet, a sliding rod, and a roller. The guiding sliding sleeve is fixedly connected to the inner wall of the electromagnetic ring. The permanent magnet is slidably connected to the inner wall of the guiding sliding sleeve. The sliding rod is fixedly connected to the outer end of the permanent magnet. The roller is fixedly connected to the outer end of the sliding rod.

[0012] A further improvement lies in that a through hole is provided at the center of the outer surface of the guiding sliding sleeve, and the sliding rod is slidably connected to the inside of the through hole. When the plastic wire passes through the inside of the wire threading cylinder, the electromagnetic ring is energized, thereby generating a repulsive force with the permanent magnet, pushing the permanent magnet to move inwards along the inner wall of the guiding sliding sleeve, and further driving the sliding rod and the roller to move inwards to contact the surface of the wire, so as to position and feed wires of plastic wires with different diameters, which is more conducive to the winding work.

[0013] A further improvement lies in that the winding device includes electric lifting rods, rotary bearings, a winding wheel, and connecting shafts. Two electric lifting rods are respectively installed at the front and rear ends on the right side of the upper surface of the bottom plate. Two rotary bearings are respectively fixedly connected to the tops of the electric lifting rods. Two connecting shafts are respectively installed at the front and rear ends of the winding wheel. The winding wheel is rotatably connected to the inside of the rotary bearing through the connecting shaft.

[0014] A further improvement is that a slide groove is provided at the rear end of the right side of the upper surface of the base plate, and an electric push rod is installed at the front end of the slide groove. The rear end of the electric push rod is fixedly connected to a connecting slider, and the connecting slider is connected to the bottom of the rear end electric lifting rod, so that the winding wheel is pushed between the two rotating bearings and aligned, and then the electric push rod is started to pull the connecting slider forward, so that the rear rotating bearing moves forward and is sleeved on the connecting shaft, so that the winding wheel is installed between the two rotating bearings, and then the electric lifting rod is started to raise the winding wheel, and winding can be carried out, and it is convenient to quickly install and disassemble the winding wheel, and then the winding motor is connected to the connecting shaft through a coupling to drive the winding wheel to rotate, thereby completing the winding work.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The wire drawing clamp device for plastic granule production, when the plastic wire passes through the inside of the wire threading cylinder, the electromagnetic ring is energized, thereby generating a repulsive force between the electromagnetic ring and the permanent magnet, pushing the permanent magnet to move inward along the inner wall of the guide sleeve, and then driving the slide rod and the roller to move inward until they are in contact with the surface of the wire, thereby positioning and feeding the plastic wires of different diameters, which is more conducive to the winding work.

[0017] 2. The wire drawing clamp device for the production of plastic particles starts the drive motor to drive the reciprocating screw to rotate inside the bearing seat, thereby driving the threaded slide on the reciprocating screw and the slider at the bottom to slide along the guide groove, making the movement more stable. At this time, the positioning wire threading unit on the top also moves accordingly, changing the direction of the plastic wire, so that the wire is evenly wound on the winding device to avoid the wire being entangled with each other.

[0032] Embodiment 2:

[0033] Refer to Figure 1 and Figure 2 , on the basis of Embodiment 1, the positioning wire feeding device includes a transverse movement unit. The transverse movement unit includes a driving motor 201, a bearing seat 202, a reciprocating lead screw 203, and a threaded slide table 204. The driving motor 201 is installed at the front end of the left side of the upper surface of the bottom plate 1, the two bearing seats 202 are respectively installed at the front and rear ends of the left side of the upper surface of the bottom plate 1, the reciprocating lead screw 203 is connected to the output end of the driving motor 201 and is rotatably connected to the inside of the bearing seat 202, and the threaded slide table 204 is threadedly connected to the reciprocating lead screw 203.

At this time, the positioning wire threading unit at its top also moves accordingly, thereby changing the direction of the plastic wire, so that the wire is evenly wound on the winding device, avoiding the situation that the wires are intertwined and knotted with each other. Compared with the existing wire drawing device that uses a fixed wire clamping clip, where the wire is fixedly wound at the same position as the winding device rotates and accumulates and knots, in this application, the reciprocating wire threading unit drives the wire to move left and right, so that the wire is evenly wound on the winding wheel 303, and the wire is not easily knotted, and the winding effect is better.
