Abstract

A disconnecting device for a plastic detonating tube splitting machine comprises a rack (1), a cylinder (2), an upper knife rest (3), an upper parting tool (4), a lower parting tool (5), a lower tool apron (6), a base (7), an jacking spring (8), a receiving groove (9) and screws (10 and 11). The disconnecting device for the plastic detonating tube splitting machine has the advantages of achieving fast and tidy cutting off of a plastic detonating tube, being convenient for workers to clean up and bundling, greatly improving labor productivity and reducing work intensity of workers.

Description

The plastic detonating tube cutting machine is used shut-off device

Technical field

The utility model relates to shut-off device, and especially the plastic detonating tube cutting machine is used shut-off device.

Background technology

Plastic detonating tube is a kind of new equipment in the non-electric initiation system, in blasting works, is used with detonator, and China began in 1978 to produce.Plastic detonating tube is that inwall has the detonate LDPE hollow hoses of medicinal powder of thin layer, has good antistatic, anti-stray current performance, and explosion velocity is stable, propagation of explosion is reliable.Plastic detonating tube is because particularly its security of its characteristics is excavated in the explosion and is widely used at metallurgy mining, roadway, and in recent years, plastic detonating tube output significantly promotes.For a long time, each manufacturer generally adopts machine production to go out the rolling primacord that joint length is 500 m, and requirement of client is several meters, tens meters length mostly.In order to satisfy client's needs, producer arranged the workman by hand primacord to be carried out fixed length, cuts off by requirement of client in the past, and then tied up primacord and pack.Because the output of primacord is very big, the split run output of general producer is about 10 myriametres (primacord processing units separate unit split run is produced 3 myriametres, can produce 9 myriametres for 3) all, and manual method labour intensity is big, inefficiency.

At present, some producer has used the primacord automatic splitting machine instead and has carried out fixed length, cuts off, but exists the primacord otch uneven, and the workman puts shortcomings such as primacord inconvenience in order.

Summary of the invention

In order to overcome above shortcoming, designed the shut-off device that a kind of plastic detonating tube cutting machine is used, with realize plastic detonating tube fast, fitly cut off, and make things convenient for the workman to put bundling in order, can raise labour productivity greatly, reduce labor strength.This device is applicable to the cut-out of small dia plastics tubings such as plastic detonating tube.After plastic detonating tube is reserved length, drive cutting knife through cylinder primacord is cut off.Upper cutter and lower cutter tightly stick together under the effect of holding out against of spring, can make otch neat.Send in the process at primacord, primacord is organized into a tuftlet, make things convenient for the workman to grasp through receiving vat.

The utility model relates to a kind of plastic detonating tube cutting machine and uses shut-off device, can accomplish quickly and efficiently primacord cut-out, compile process, by cylinder as propulsion source.Can cut off many primacords at every turn, increase work efficiency.

This device mainly comprises frame 1, cylinder 2, and upper tool post 3, upper cutter 4, lower cutter 5, following tool rest 6, base 7 holds out against spring 8, receiving vat 9,

screw

10,11.

Cylinder 2 is fixed on the frame 1, and upper tool post 3 is fixed on the lower end of the cylinder rod of cylinder 2, upper cutter 4 be fixed on upper tool post 3 below, the leading flank of the trailing flank of upper cutter 4 and lower cutter 5 is adjacent to.Lower cutter 5 is fixed on down the front of tool rest 6.Following tool rest 6 be fixed on through

screw

10,11 base 7 the rear portion above.Hold out against spring 8 and be compression spring, an end withstands on the base 7, and the other end withstands on down the back of tool rest 6.Receiving vat 9 is fixed on above the forward of base 7, and aligns with the primacord outlet of lower cutter 5.

On following tool rest 6, have the passage of primacord, channel entrance is the hydraucone shape, helps primacord and sends down tool rest 6 from the outside to.

The left end of receiving vat 9 is import, with the outlet of the primacord of lower cutter 5 relatively, width is a bit larger tham the lengthwise dimension of 10 primacords outlets, the right-hand member of receiving vat 9 is narrower for outlet, just is organized into thinner a branch of through receiving vat 9 back 10 primacords.

Specific embodiment

screw

10,11 base 7 the rear portion above.Hold out against spring 8 and be compression spring, an end withstands on the base 7, and the other end withstands on down the back of tool rest 6.Receiving vat 9 is fixed on above the forward of base 7, and aligns with the primacord outlet of lower cutter 5.On following tool rest 6, have the passage of 10 primacords, channel entrance is the hydraucone shape, helps primacord and sends down tool rest 6 from the outside to.The left end of receiving vat 9 is import, with the outlet of the primacord of lower cutter 5 relatively, width is a bit larger tham the lengthwise dimension of 10 primacords outlets, the right-hand member of receiving vat 9 is narrower for outlet, just is organized into thinner a branch of through receiving vat 9 back 10 primacords.Working process: 10 primacords are sent to from following tool rest hydraucone, passed lower blade, get into receiving vat, when primacord length reached required value, primacord stopped to send to, and the cylinder band upper cutter and moved downward, and 10 primacords are cut off.The workman packs up 10 primacords at the receiving vat the other end again.

When finding in the use that upper cutter 4 and lower cutter 5 are fitted closely, the

fixing screw

10,11 of tool rest is down unclamped, upper cutter 4 and lower cutter 5 are adjacent to holding out against spring 8 effects, and then tighten

screw

10,11.
