Abstract

The invention provides a device for manufacturing a portable rope head. A plastic coating device is arranged at one side of a cut-off device in a fixed length manner; a tensioning device is arranged outside the plastic coating device, wherein the length of the cut-off device is fixed by the centers of a cutter and the plastic coating device; a dual-plastic-coating-head die cavity with dividing cutter edges is arranged in the die cavity of the plastic coating device, rope guiding slots are formed in two sides of the dual-plastic-coating-head die cavity, and a portable rope is arranged on the tensioning device; a plurality of cut-off devices, dual-plastic-coating-head die cavities of the plastic coating devices and tensioning devices are arranged in parallel. The portable rope has an integrated length in production, one end of the portable rope is straightened at the cut-off device, so that the portable rope and the tension device form a straight line; plastic injection is performed in the rope guiding slots of the dual-plastic-coating-head die cavity, so that two plastic coating heads are formed on the portable rope once; fixed-length circulating plastic coating is performed from the middle parts of the two plastic coating heads to the cut-off device, and the plastic coated portable rope which is drawn out of the cut-off device is cut at the cut position to form a portable rope finished product; portable ropes can be constantly and continuously produced in a reciprocating circulation manner.

Description

A kind of device of making portable fag end

Technical field

The present invention relates to producing device and the method for the fag end of the third dragon or plastic ties, specifically a kind of device of making portable fag end.

Background technology

The plastic standard of portable fag end is as Fig. 1, at the two ends of a rope 1 plastic 2, can bear weight more than 50kg, especially for the portable rope of carrying heavier object, as carry the portable rope of battery, requirement is that the two ends of rope 1 are in plastic 2 middle, to can bear the strength of heavier object.The portable rope that also has handbag, its structure only can be applicable to lighter object.

Current handle fag end plastic 2 is all first rope 1 to be cut off according to product length, then two is placed on respectively and in die cavity, carries out pre-buried injection moulding; Because rope 1 one end in die cavity is compressed by sealing face, the other end is in free state, in the time of injection mo(u)lding, because of the flowing and internal pressure unbalanced of plastic cement, can cause the termination of rope 1 to depart from plastic center, even floats on surface; Plastic 2 of rope 1 departs from can cause package power deficiency, affects the use function of rope, there will be security incident when serious, and the product after its processing as shown in Figure 2.

Moreover the rope two ends of cutting off are because self elasticity of rope can cause the loose shape of its fag end, make plastic not moulding, lose time and raw material.

Summary of the invention

Fag end is all the time in plastic center when ensureing that portable fag end is plastic in the present invention, and the fag end of avoiding occurring rope departs from, empty bag causes pulling-out force deficiency, specially proposes a kind of device of making portable fag end.

Technical scheme of the present invention is for this reason, a kind of device of making portable fag end, comprise shearing device, it is characterized in that: the side fixed length at shearing device is provided with plastic device, plastic device is provided with swelling device outward, and wherein shearing device is the center fixed length with its cutting knife and plastic device, is provided with double-contracting and moulds head mould chamber in the die cavity of plastic device, and from be provided with conductor rope groove to both sides, rope is housed on swelling device.

Improvement to such scheme is: double-contracting moulds that in head mould chamber, to be provided with the cutter of all demarcating stupefied.

Improvement to such scheme is: head mould chamber is moulded in the double-contracting of shearing device, plastic device, swelling device is multiple being arranged in parallel.

Beneficial effect:

The present invention's rope in the time producing is an entire length, and at shearing device place, stretching rope and the swelling device of making forms straight line in one end of rope, and in conductor rope groove, then double-contracting is moulded to injection moulding in head mould chamber, make rope once form two plastic heads; It is plastic that so the fixed length circulation of shearing device place is walked in centre of latter two plastic head, pulled out simultaneously plastic good rope outside shearing device cut-off part cut off rope finished product, then reciprocation cycle just continuously continuation produce rope.

This device is not cut off rope, after plastic with the entirety circulation of a rope, cut off into again finished product, reduce the operation of cutting off separately, the use of overall rope simultaneously, when plastic, fag end is all the time in plastic center, avoid occurring that rope head departs from, empty bag, ensured the quality of product, make it meet the requirement of product.

Double-contracting moulds that in head mould chamber, to be provided with the cutter of all demarcating stupefied, and when injection moulding, two fag ends of an injection moulding boundary, reduced man-hour, improved effect, also facilitated the cut-out of cutting off operation.

When multiple parallel connections of the die cavity of shearing device and plastic device and swelling device realize many ropes, produce, significantly increase work efficiency.

Adopt the present invention effectively to ensure that rope, all the time in center, has improved the stability of producing when plastic, through producing checking in enormous quantities, plastic pulling-out force significantly improves.

Brief description of the drawings

Fig. 1 is the structure chart of rope finished product.

Fig. 2 is the structure chart of defective rope finished product.

Fig. 3 is structural representation of the present invention.

In figure, 1 is rope, the 2nd, and plastic, the 3rd, shearing device, the 4th, cutting knife, the 5th, plastic device, the 6th, swelling device, the 7th, head mould chamber is moulded in double-contracting, and the 8th, the cutter of all demarcating is stupefied, and the 9th, conductor rope groove, X is fixed length.

Detailed description of the invention

The present invention as shown in Figure 3.

A kind of device of making portable fag end, comprise shearing device 1, a side fixed length X at shearing device 3 is provided with plastic device 5, the outer swelling device 6 that is provided with of plastic device 5, wherein shearing device 3 is the center fixed length X with its cutting knife 4 and plastic device 5, in the die cavity of plastic device 5, be provided with double-contracting and mould head mould chamber 7, and from be provided with conductor rope groove 9 to both sides, rope 1 is housed on swelling device 6.

Double-contracting is moulded and in head mould chamber 7, is provided with the cutter of all demarcating stupefied 8.

Head mould chamber 7 is moulded in the double-contracting of shearing device 3, plastic device 5, swelling device 6 is multiple being arranged in parallel.

In the time producing, rope 1 is an entire length, and at shearing device 3 places, stretching rope 1 and the swelling device 6 of making forms straight line in one end of rope 1, and in conductor rope groove 9, then double-contracting is moulded to the interior injection moulding in head mould chamber 7, make rope 1 once form two plastic 2; It is plastic that so the shearing device 3 fixed length X of place circulations are walked in latter two centre of plastic 2, pulled out simultaneously plastic good rope 1 outside shearing device 3 cut-off part cut off rope finished product, then reciprocation cycle just continuously continuation produce rope.
