Definitions

  • the invention relates to methods for processing worn, damaged, or discarded automobile and tractor tires that are to be disposed of by cutting out the tread portion, sidewalls and side rings from them and can be used to prepare for grinding tires, both textile and metal locor .
  • a known method of dividing the tire into five parts in which the fixed tire is compressed in the axial direction until the bending is deformed in the belt-tread part, the tire is rotated, the frame-belt-tread ring is cut out with the knives moving in the radial direction, two sidewalls are separated and the side rings are removed from the sidewalls by tearing (patent RU »2188125).
  • the disadvantage of this method is significant difficulties or the inability to cut into the indicated parts of the tires having damage to the supporting structure (frame), which does not allow the tire to rotate with the necessary accuracy and tear out the side rings.
  • Another disadvantage is the difficulty in implementing the method, requiring several separate drives for compressing the tire, its rotation and tearing out the side rings.
  • Another disadvantage is the complexity of the method due to the large number of operations that are heterogeneous in nature and the considerable time required for sequential operations to separate the tire, since three parts of the tire are obtained by cutting (tread, two sidewalls), and two parts are obtained by sequentially tearing the side rings from the sidewalls.

  • the device is equipped with a semi-automatic control system, as well as a system for supplying lubricating-cooling fluid to the cutting zones.

  • a known method of cutting and packaging tires according to patent RU N2221 1 145, in which they carry out the cutting of tires into individual fragments and their packaging. After separating one sidewall from the tread portion, the sidewall is pressed into the tire cavity. The next tire with the failed sidewall is pressed into the remaining space until a packet is formed from the required number of tires, the tread parts of the tires are cut along the generatrix, and adjacent tires are fixed to fix the package.
  • the disadvantage of this method is that the utilized tire is cut into three parts - the tread part and two sidewalls with side rings. Given that in the tread part, sidewalls and side rings of rubber, the chemical composition differs from each other, it is impossible to sort the tire by its qualitative composition in this way. Cutting tires into components with different mounting diameters is carried out at various installations requiring readjustment. In addition, the known method does not provide a full range of operations for cutting tires during their disposal without reinstalling them.

  • the invention uses specially designed knives for cutting metal cord yarns along the border of their occurrence in the frame.
  • the disadvantage of the prototype method is that the cutting of the tire into its component parts - the tread part and two sidewalls with bead rings - with different landing diameters is carried out at various installations requiring readjustment.
  • the remaining (side) fragments mainly consisting of rubber, contain on-board metal rings, for the removal of which additional operations and devices are necessary.
  • the side fragments freed from the side rings to obtain secondary raw materials in the form of crumb rubber from them must be additionally subjected to an energy-intensive mechanical grinding process, but in this case, the quality of the raw material will be unsatisfactory due to the presence of fragments and ends of the cord threads, which cannot be avoided disposal indicated way.
  • the method described above is low productivity due to the long time spent on setting up equipment, sharpening and re-grinding of the cutting tool, which inhibits its use.
  • the use of disk knives for cutting tires with a complex feed system and carrying out an insufficient cutting line requires two cuts for cutting the tread portion. All this narrows the technological capabilities of the method as a whole and reduces the performance of cutting tires into components.
  • the present invention is aimed at eliminating the above-mentioned disadvantages, namely, expanding the technological capabilities of the method by implementing the full range of operations necessary for cutting the tire to be used into parts of operations and expanding the range of sizes of tires to be recycled without reinstalling them on other machines, which will also significantly increase processing productivity.

Abstract

L'invention concerne des procédés de retraitement de pneumatiques d'automobiles et de tracteurs en vue de leur recyclage, et peut être utilisée pour la préparation au broyage de pneumatiques, qu'ils soient textiles ou à câblé métallique. Le but de l'invention est d'élargir les capacités industrielles du procédé tout en augmentant la productivité du traitement. Le procédé comprend deux étapes : on commence par découper et éliminer la partie bande de roulement (2) du pneumatique (1), et après les avoir pressées l'une contre l'autre et fixées, les parois latérales restantes (3) sont découpées de l'anneau du talon (4). Les deux étapes se font en un seul cycle industriel en utilisant le même instrument de coupe qui consiste en une scie à ruban à moteur (6). Lors du processus de découpe de la partie bande de roulement et des parois latérales, la scie à ruban est tout d'abord amenée dans un plan horizontal par rapport au pneumatique de manière à ce qu'elle forme une série de gorges transversales (8) lors de la découpe puis du retournement du pneumatique le long de sa surface externe, après quoi on effectue une découpe longitudinale par rapport à la tangente du pneumatique tout en le faisant tourner, réalisant ainsi la découpe de la couche externe du caoutchouc.
