Technical Field

The invention relates to the technical field of kinescope separating devices, in particular to a full-automatic kinescope separating device.

Background

One of the difficulties in the disassembly of discarded televisions and computers is the handling of the picture tube (CRT). It can be divided into a cone tube and a fluorescent screen. The fluorescent screen has one layer of fluorescent material inside it, which is a mixture of several kinds of material and contains Zn, Cd as rare metal, Ag, etc. The glass of the kinescope cone contains 9.9-21.0% of lead oxide. The screen is a glass containing 0.3-13.3% palladium oxide, 0.5-10.7% strontium oxide, 5.0-10.0% sodium oxide, 5.0-10.0% potassium oxide, etc. Many of these substances, such as lead, once they enter the soil, severely contaminate water supplies, ultimately endangering humans, plants and microorganisms, and also affecting the brain development of children. On the other hand, in the picture tube, the proportion of the phosphor screen glass, the funnel glass and the metal is more than 99%, so that the separation and recovery of these parts are the key to the resource recovery of the picture tube. The picture tube is therefore treated not only for environmental protection but also for resource reuse. If the screen and the cone tube of the scrapped kinescope are separated, after being crushed and cleaned, the screen and the cone tube can be used as raw materials and then respectively manufactured, thereby changing waste into valuable. However, the purity requirements of the raw materials used to make the faceplate or the funnel are high, which requires that the notch be flush when cutting the faceplate or the funnel of the tube, and does not allow the lead-containing funnel glass to be introduced into the glass of the faceplate. The present kinescope cutting machine adopts a metal wire or belt heating and cooling cutting process, and its principle is that a metal wire or belt is winded on the joint of kinescope fluorescent screen glass and cone tube glass, then the metal wire or belt is electrically heated, and after heated for a period of time, it is cut off and cooled, and by utilizing the principle of glass expansion with heat and contraction with cold and the characteristic of glass brittleness, the joint of two glasses can produce internal stress exceeding its strength to break, so that the separation of two glasses can be implemented. However, when cutting a large-sized picture tube, the picture tube cutting machine often has uneven cuts or glass is easily broken, and the using effect is not good.

Chinese patent publication No. CN2828035Y discloses a kinescope screen cone cutting separator with a nicking device, which comprises a base, a cutting table on the base, a nicking table on the base, a rotary table on the nicking table for placing the kinescope, and a cutter beside the rotary table for nicking the kinescope.

After the nicking device scores, a stress concentration trace is manufactured at a part needing to be cut and separated in advance, so that a smooth fracture is easy to obtain and the glass is not easy to break when the glass is cut; however, the kinescope after being scored for one circle needs to be manually transported when being moved to a cutting workbench, the kinescope after being cut needs to be transported manually, the kinescope after being cut has a sharp notch, the kinescope is easy to scratch during manual transportation, a great amount of fluorescent powder exists in a fluorescent screen, the fluorescent powder still needs to be manually collected after being transported, and the powdery fluorescent powder can erode workers.
