Description

Technical Field

[0001] The invention relates to a plastic shaped yarn production device, in particular to a plastic shaped yarn coating component. Background Art

[0002] At present, a Chinese patent with publication number CN107041622A discloses a method for manufacturing plastic shaped yarn, comprising the following steps: a first step, preparing loess powder; a second step, preparing an extract; a third step, preparing pomegranate seed oil; a fourth step, adding a polymer, pomegranate seed oil and a coupling agent in proportion into a high-speed mixer and stirring for 15 to 30 minutes; a fifth step, adding a formulated amount of a natural antibacterial agent and continuing to stir for 3 to 8 minutes; a sixth step, feeding it into a twin-screw machine for extrusion granulation and drying; a seventh step, feeding it into a melt spinning machine for melt spinning at 220-230 degrees Celsius; and an eighth step, cooling and shaping.

[0003] After the plastic shaping wire is cooled and shaped, in order to facilitate the subsequent processing of the plastic shaping wire, workers need to manually use a film to tightly wrap the plastic shaping wires so that the plastic shaping wires are not easy to disperse. However, the manual film wrapping process takes a long time and has low efficiency. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a plastic shaping yarn coating component, which has the advantage of being able to efficiently coat a plurality of plastic shaping yarns.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a plastic shaping silk film coating assembly, comprising a frame, a mounting frame is fixed on the frame, and a wire passing hole is passed through the mounting frame; a rotating ring is rotatably connected to the mounting frame, and the inner cavity of the rotating ring is connected to the wire passing hole, and a plurality of rotating rollers are circumferentially rotatably connected to the rotating ring; a brake belt surrounding the plurality of rotating rollers is fixed on the mounting frame, and an opening is opened on the brake belt; a rotating ring driving member is provided on the mounting frame, and the rotating ring driving member is used to drive the rotating ring to rotate circumferentially; a traction mechanism is provided on the mounting frame, and the traction mechanism is used to clamp the end of the film and pull the film through the opening and the gap between two adjacent rotating rollers in sequence; a cutting mechanism is provided on the mounting frame, and the cutting mechanism is used to cut the film.

[0006] Through the above technical scheme, in the first step, the ends of the bundled plastic shaping wires are passed through the wire-passing hole and placed inside the rotating ring; in the second step, the ends of the rolled film are clamped by a traction mechanism, and the film is pulled toward one side of the bundled plastic shaping wires through the traction mechanism, so that the film passes through the opening and the gap between two adjacent rotating rollers in turn; in the third step, the rotating ring driving member is used to control the circumferential rotation of the rotating ring. During this process, the rotating rollers on the rotating ring press the film and push the film to rotate, so that the film close to the wire-passing hole is wound around the bundled plastic shaping wires, and the film away from the wire-passing hole is wound around the outside of the several rotating rollers, so as to achieve the purpose of material storage. The fourth step is to loosen the film and move it to the outside of the rotating ring after a certain number of turns of film are wrapped around the bundled plastic shaping wires. The fifth step is to uniformly control the plastic shaping wires to pass through the threading hole so that the film can be evenly wrapped around the bundled plastic shaping wires. The sixth step is to clamp the film using the traction mechanism and cut the film using the cutting mechanism after enough film is wrapped around the bundled plastic shaping wires. The seventh step is to continuously rotate the rotating ring so that the film wrapped around the rotating rollers continues to be wrapped around the outside of the plastic shaping wires. When all the plastic shaping wires on the rotating rollers are wrapped around the outside of the plastic shaping wires, the coating of the plastic shaping wires is completed. The brake band set on the mounting frame can delay the film so that the film can be tightly wrapped around the outside of the plastic shaping wires. This process requires almost no human intervention, and the coating process takes a short time and is highly efficient.

[0007] Preferably, the rotating ring driving member includes a driving motor fixed on the mounting frame, a synchronous wheel fixed on the output shaft of the driving motor, a plurality of belt teeth circumferentially fixed on the outer peripheral wall of the rotating ring, and a synchronous belt tensioned between the synchronous wheel and the rotating ring.

[0012] Preferably, the cutting mechanism includes a mounting plate fixed on the mounting frame, a tool driving member fixed on the mounting plate, a movable tool fixed on the output end of the tool driving member, and a fixed tool fixed on the mounting frame and opposite to the movable tool.

[0013] Through the above technical solution, when it is necessary to cut the film, the movable tool is controlled by the tool driving component to move toward the side of the fixed tool. When the blade of the fixed tool and the blade of the movable tool respectively contact the two sides of the film, the fixed tool and the movable tool cooperate to start cutting the film. When the blade of the fixed tool contacts the blade of the movable tool, the film cutting is completed.

[0017] Through the above technical solution, when the detection mechanism detects that a roll of film is about to run out, the detection mechanism controls the film connecting mechanism to stick the head of the new film with tape to the tail of the old film that is about to run out. This setting can improve the utilization rate of the film and reduce the waste of the film on the one hand, and ensure the continuous operation of the film packaging assembly on the other hand, and improve the use efficiency of the film packaging assembly.

[0019] Through the above technical solution, when in use, the film connecting rod is controlled to rotate by the film connecting driving part so that the two film connecting rods are close to each other. At the same time, the two film connecting rollers arranged on the ends of the two film connecting rods can push the two films close to each other.

When a roll of film is used up, the pulling force exerted by the film on the guide roller disappears, and the spring drives the auxiliary plate to slide on the column, so that the trigger block gradually approaches the travel switch.

The specific cutting process is as follows: the knife seat is controlled to approach the rotating ring by the knife seat driving member, the knife holder is controlled to move downward by the knife holder driving member, and the cutter is controlled to rotate circumferentially by the cutter driving member. When the rotating cutter contacts the plastic shaping wire coated with a film, the cutter starts to cut the plastic shaping wire coated with a film.
