Description

Technical Field

[0001] The utility model belongs to the technical field of plastic processing, and particularly relates to a PVC sheath material processing device. Background Technique

[0002] A PVC sheath is a flat cable formed by wrapping an insulating material around a stranded conductor of multiple copper wires and pressing the sheath material through a high-tech automated production line. It has the advantages of being soft, capable of being bent and folded arbitrarily, having a relatively thin thickness, small volume, simple connection, convenient disassembly, etc.

[0003] During the sheath processing, a variety of plastic raw materials are required. After mixing, they are extruded by an extruder to form a sheath material. If the raw material particles are too large during the processing, the same kind of raw material may accumulate together during the high-temperature melting process, making it difficult to mix, and ultimately resulting in unqualified products.

And the mixing mechanism 8 is communicated with the sealing cover 7. The sealing cover 7 and the rectangular plate 20 are detachably connected. In this embodiment, the sealing cover 7 and the rectangular plate 20 are snap-connected. However, when implementing this technical solution, the sealing cover 7 and the rectangular plate 20 can also be magnetically hooked, etc., and all can achieve the same technical effect as this technical solution. A screening mechanism is further provided inside the sealing cover 7, which is used for screening the raw materials crushed by the crushing mechanism 9 to prevent uncompletely crushed particles from existing during the crushing process and affecting the processing of the sheath material.

[0028] As Figure 1 and Figure 2 shown, the processing device further includes an external support 14. An annular plate 15 is fixedly provided at the top end of the external support 14. Rectangular limit blocks 19 are fixedly and symmetrically provided at the bottom end of the annular plate 15. A large gear 16 is provided inside the annular plate 15. The large gear 16 is slidably connected between the two rectangular limit blocks 19. A small gear 17 is rotatably provided on the annular plate 15. A first motor 18 is connected to the small gear 17. The first motor 18 is fixedly connected to the annular plate 15. The first motor 18 drives the small gear 17 to rotate, and the rotation of the small gear 17 drives the large gear 16 to rotate.

[0029] As Figure 1 shown, a plurality of storage barrels 12 are fixedly provided on the large gear 16. The plurality of storage barrels 12 are arranged in a circumferential array. A feed pipe 13 is connected to the top end of the storage barrel 12. The feed pipe 13 is plastically deformable. A quantitative discharging mechanism 10 is provided at the bottom end of each of the plurality of storage barrels 12. A valve 11 is provided on the quantitative discharging mechanism 10 for controlling the discharging amount of the quantitative discharging mechanism 10.

The large-particle raw materials remain on the sieve plate 23 and are subsequently collected centrally.

[0031] During use, the raw materials for producing the sheath material are respectively stored in the storage barrels 12. The first motor 18 drives the large gear 16 to rotate, aligning the storage barrels 12 with the feeding openings at the top of the crushing mechanism 9 in sequence, and realizing the quantitative discharging of each raw material through the quantitative discharging mechanism 10. After each component raw material enters the crushing mechanism 9, the crushing mechanism 9 is started to crush each raw material.

By driving the reciprocating lead screw 25 to rotate through the second motor, the reciprocating movement of the sieve plate 23 is realized. The screened raw materials enter the extrusion mechanism 2 through the feeding funnel 4, and the extrusion mechanism 2 extrudes the sheath material at high temperature. For the large-particle raw materials remaining on the sieve plate 23, the sealing cover 7 can be opened through the telescopic cylinder 6 to facilitate the collection and reprocessing of the large-particle raw materials remaining on the sieve plate 23.
