Description

Technical Field

[0001] The present invention belongs to the technical field of waste tires, and particularly relates to a full-automatic waste tire circumferential cutting and bead cutting and wire stripping system and method. Background Art

[0002] With the increasing number of scrapped waste tires, the secondary utilization of waste tire materials has attracted more and more attention. There are still a large number of recyclable materials in waste tires, such as metal materials like the steel wire ring in the bead and the steel belt in the belt layer. At present, there is no relatively perfect waste tire treatment method, and there is no complete directional treatment system for each semi-component of waste tires. Most tires are damaged, resulting in low utilization rate of waste materials and great material waste. At present, there are some simple devices for bead circumferential cutting and wire stripping, but they are all manual operations. Manual operation has low precision, high labor cost, and certain operation risks. Moreover, the continuity of tire treatment is poor, and only single bead circumferential cutting or bead wire stripping can be carried out, with low efficiency and unable to meet the working conditions when dealing with a large number of waste tires. There is also no complete circumferential cutting and wire stripping system for tire beads, which has caused certain obstacles to the industrialization and automation development of waste tires.

The entire process of waste tire treatment can be automated, reducing manual labor. Since all mechanized processing is adopted, the work efficiency is improved, and it can meet the large-scale treatment of waste tires.

[0090] Step 1: The front-end conveying mechanism conveys the waste tire to the rotary handling mechanism, and the rotary handling mechanism rotates to convey the waste tire to the bead cutting mechanism;

[0091] Specifically: The tire front-end conveying mechanism 100 is responsible for conveying the complete waste tire from the waste tire shelf to the tire rotary handling mechanism 200 through the climbing conveying chain assembly 110 and the horizontal conveying chain assembly 120. The clamping assembly of the tire rotary handling mechanism 200 moves, that is, the motor drives the lead screw to rotate, and the two jaws move relatively. When the two jaws approach each other, the tire is clamped; the rotary drive assembly 240 acts to drive the rotary table to rotate, so that the waste tire rotates into the working area of the bead cutting mechanism;

[0093] Start the water jet, which can spray high-pressure water jets to cut the waste tire. The cutting accuracy is high and it is pollution-free. Through the linkage control of the rotary power drive, the horizontal module, and the vertical module, the water jet can cut any position on the side of the waste tire, so as to cut out a complete bead.

[0094] Step 2: The handling hand lifting mechanism, handling hand rotating mechanism, handling hand telescopic mechanism, and handling hand mechanism of the bead handling device are linked to clamp the bead; then the bead cutting mechanism performs bead cutting, and the water jet component of the bead cutting mechanism performs three-axis linkage cutting; during the cutting process, if the bead handling device obstructs the cutting, the handling hand rotates and then starts the rotary motor 554, and the handling hand rotary table 551 rotates, so as to rotate the waste tire, so that the tire cutting mechanism 300 can continue to cut.

[0095] After the bead cutting is completed, the bead handling device places the bead at the bead cutting and wire stripping device. During this process, the moving roller assembly in the bead cutting and wire stripping device adjusts the distance between the moving rollers according to the size of the bead to be cut, and then the bead is placed on the moving rollers; the horizontal moving slide rail assembly acts, the clamping component clamps the bead, and the cutting knife component acts to cut off both sides of the bead in sequence to cut the bead into two parts; the horizontal moving slide rail assembly and the clamping component work together to pull the two cut beads towards the inner side wall of the workbench respectively to pull the bead closer and flatten it; the horizontal moving slide rail assembly acts to convey the flattened bead to the bead stripping mechanism through the bead traction mechanism; the bead stripping component of the bead stripping mechanism acts to perform crushing treatment on the bead; the wire traction component acts, and the master and slave grippers act to clamp the stripped wire ring and drop it into the wire storage box.
