DETAILED DESCRIPTION

[0023] The following is combined with Figure 1 To the attached Figure 5 The principles and features of the present invention are described, and the examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] A plastic wire bundling device comprises a frame, a feeding assembly 100, a bundling assembly 200, a wire feeding assembly 300, a material pulling assembly 400, and a cutting assembly 500 mounted on the frame. The feeding assembly 100 feeds plastic wire into the bundling assembly 200. The bundling assembly 200 uses the wire fed by the wire feeding assembly 300 to bundle the plastic wire. The material pulling assembly 400 then pulls the plastic wire bundle, which is then cut to length by the cutting assembly 500. Finally, the material pulling assembly 400 continues pulling, and the plastic wire bundle falls into a material receiving container. The detailed structure is described below.

[0025] The feeding assembly 100 includes a feeding roller group 110, which includes a driving roller 111 and a first driven roller 112. The driving roller 111 drives the first driven roller 112 to rotate relative to each other under the drive of the motor, clamping the plastic wire and feeding it into the bundling assembly 200. Figure 5As shown, in one embodiment, to prevent the plastic filaments sandwiched between the active roller 111 and the first driven roller 112 from moving out of the gap, the active roller 111 is configured with an "I"-shaped cross-section, and the first driven roller 112 precisely matches the inner concave portion of the "I" shape. To guide the plastic filaments, in one embodiment, the loading assembly 100 further includes a guide ring 120, a guide roller 130, and a guide tube 140 disposed on the frame. The guide roller 130 is provided with a groove, and two guide tubes 140 are provided, one on each side of the loading roller assembly 110. During use, multiple strands of plastic filaments pass through the guide ring 120, then through the groove on the guide roller 130 and into the guide tube 140 above the loading roller assembly 110. The plastic filaments then pass through the relatively rotating active roller 111 and the first driven roller 112, and are finally fed from the guide tube 140 below the loading roller assembly 110 into the bundling assembly 200. In one embodiment, the first driven roller 112 can be driven by a cylinder and away from the active roller 111, so as to facilitate maintenance or cleaning of possible waste.

[0026] The bundling assembly 200 includes a turntable 210, a wire clamping module 220 disposed on the turntable 210, and a push-out module 230. The turntable 210 is provided with a central through hole 211 for the plastic wire to pass through, and the drive mode of the turntable 210 can be a belt drive. The feeding assembly 100 feeds the plastic wire into the central through hole 211, and the wire feeding assembly 300 feeds the bundle wire into the wire clamping module 220. The wire clamping module 220 clamps the bundle wire and rotates around the axis of the turntable 210 driven by the turntable 210 to bundle the plastic wire into a bundle. The number of rotations can be set as needed. Specifically, the wire clamping module 220 includes a first cylinder 221, a base 222, and a chuck 223 disposed on the base 222 and slidably connected to the base 222. The first cylinder 221 can push the chuck 223 to move and clamp the bundle wire on the base 222. In one embodiment, the base 222 is provided with a groove, and the chuck 223 is provided with a protruding rod. The first cylinder 221 pushes the chuck 223 downward, and the rod moves downward, pressing the wire into the groove on the base 222. The base 222 is also provided with a push rod 224 that can push the chuck 223 upward. The push rod 224 moves upward, pushing the chuck 223 upward, so that the rod on the chuck 223 moves out of the groove, thereby releasing the wire. The ejection module 230 includes an ejection plate 231 and a second cylinder 232 that drives the ejection plate 231. The ejection plate 231 can push the push rod 224 to move.

[0027] The wire feeding assembly 300 includes a wire feeder 310 and a cutter module 320. The cutter module 320 includes a cutter seat 321 disposed at the end of the wire feeder 310, a cutter head 322 disposed on the cutter seat 321 and slidably connected to the cutter seat 321, and a third cylinder 323. The cutter seat 321 is provided with a wire outlet hole 324. The third cylinder 323 drives the cutter head 322 to move and cut the binding wire at the wire outlet hole 324. In one embodiment, a groove is provided on the cutter seat 321, and the wire outlet hole 324 is provided in this groove. The cutter head 322 is also slidably provided in this groove. This design allows the cutter head 322 to have better stability when cutting the bundled wire. The wire feeder 310 can use a wire feeding device commonly used in the prior art, and its structure will not be repeated here. The wire feeder 310 feeds the bundled wire into the wire outlet hole 324. A tensioning device may be provided between the wire roller 330 and the wire feeder 310 to adjust the tightness of the wire bundle so that the wire bundle feeding is more uniform and stable.

[0028] The drawing assembly 400 includes a drawing roller 410 and a second driven roller 420. The drawing roller 410 drives the second driven roller 420 to rotate relative to each other under the drive of the active roller 111, clamping the plastic filament and pulling it out from the central through hole 211. The drawing roller 410 and the second driven roller 420 are arranged in the same manner as the active roller 111 and the first driven roller 112. In one embodiment, the active roller 111 and the drawing roller 410 are respectively provided with sprockets, and the two sprockets are connected by a chain. In one embodiment, in order to prevent relative sliding between the drawing roller 410 and the second driven roller 420, which affects the drawing of the plastic filament bundle, the drawing roller 410 and the second driven roller 420 are respectively provided with universal joints, and the other ends of the two universal joints are respectively provided with gears that mesh with each other. This design can ensure the synchronous rotation of the drawing roller 410 and the second driven roller 420, making the drawing more stable. Furthermore, to increase the friction of the second driven roller 420 and ensure that the pulling roller 410 and the second driven roller 420 can smoothly pull all the plastic filaments when they rotate, synchronous belt teeth are machined on the surface of the second driven roller 420, and a rubber synchronous belt is installed on the surface of the second driven roller 420. The entire circular surface of the second driven roller 420 is covered with the rubber synchronous belt. Installing the synchronous belt not only increases friction but also facilitates replacement of the synchronous belt if it wears out.

[0029] The cutting assembly 500 is located below the drawing assembly 400 and includes two blades that can move closer or farther away from each other. Specifically, the two blades are blade 1 and blade 2. Blade 1 is fixed to the frame, and blade 2 is driven by a cylinder and moves closer or farther away from the blade along a slide rail to complete the cutting of the plastic tow.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
