Description

Technical Field

[0001] The present invention relates to the technical field of mold cleaning, in particular to a cleaning device for tire mold tread blocks. Background Art

[0002] Tire molds are important tools used in the tire vulcanization process. During use, tire molds will be contaminated by the combined deposition of rubber, compounding agents, and release agents (used in the vulcanization process) (the main pollutants are sulfides, inorganic oxides, silicone oil, carbon black, etc.). After repeated use, the tread blocks of tire molds will develop contaminated dead zones in some patterns. When cleaning tire mold tread blocks, laser cleaning is generally used. Laser cleaning can guide light to the dead corners of the mold or areas that are difficult to remove contamination for cleaning.

When the vertical side of the L-shaped plate 27 contacts the second ramp block 26, the vertical side of the L-shaped plate 27 slides between the second ramp block 26; Preferably, the tire mold pattern blocks can be continuously cleaned horizontally and vertically, and multiple laser heads 11 are at the same distance from the tire mold pattern blocks during horizontal or vertical cleaning, ensuring the cleaning effect and avoiding the situation where the laser head 11 is at different distances from the pattern blocks during cleaning, resulting in uneven cleaning quality.

[0024] The working principle of the present invention is as follows: when it is necessary to clean the tire mold pattern block, first place the tire mold pattern block on the top of the electromagnet plate 4; Then, the conveyor belt 1 is started to drive the base 21 to move. It should be noted that the motor controlling the conveyor belt 1 is an intermittent motor to achieve intermittent conveying of the conveyor belt 1. The movement of the base 21 drives the shaft 22 to move. The movement of the shaft 22 drives the electromagnet plate 4 and the tire mold pattern block on its top to move. When the copper disk 25 and the copper plate 15 come into contact, the electromagnet plate 4 is energized to generate suction, and at this time, the electromagnet plate 4 can adsorb and fix the tire mold pattern block. When the gear 24 and the rack 17 are in contact and meshing, the gear 24 rotates. The rotation of the gear 24 drives the shaft 22 to rotate 90 degrees, causing the torsion spring 23 to generate a torsion force. The rotation of the shaft 22 drives the electromagnet plate 4 to rotate 90 degrees. It should be noted that the electromagnet plate 4 rotates 90 degrees when it moves to the bottom of the U-shaped frame 2. Then, the driving motor 3 is started to drive the rotating shaft 19 to rotate, and the rotation of the rotating shaft 19 drives the turntable 5 to rotate. The rotation of the turntable 5 drives the fixed plate 8 and the second spring rod 13 to rotate with the turntable 5 as the center. The rotation of the fixed plate 8 drives the strip plate 9 to rotate. The rotation of the strip plate 9 drives the first spring rod 10 and the laser head 11 to rotate with the turntable 5 as the center, so that the laser head 11 can move in an arc trajectory when cleaning the tire mold pattern block, ensuring that the distance between the laser head 11 and each part of the tire mold pattern block that needs to be cleaned is the same during the cleaning process, avoiding the situation where the distance between the laser head 11 and the tire mold pattern block is not fixed, resulting in different cleaning effects; In addition, when cleaning the tire mold pattern block, the second spring rod 13 rotates with the turntable 5 as the center, which will drive the first ramp block 14, the semicircular plate 18 and the L-shaped plate 27 to rotate. When the first ramp block 14 contacts the ramp strip 7, the horizontal cleaning of the tire mold pattern block is completed at this time, which will cause the first ramp block 14 and the telescopic end of the second spring rod 13 to move away from the turntable 5, and cause the second spring rod 13 to generate a pulling force. The telescopic end of the second spring rod 13 moves and drives the semicircular plate 18 to move. When the semicircular plate 18 contacts the pin 12, it drives the pin 12 to move. The movement of the pin 12 drives the telescopic end of the first spring rod 10 and the laser head 11 to move downward, so that the height of the multiple laser heads 11 can be arranged according to the shape of the side cross-section of the tire mold pattern block. It should be noted that the semicircular plate 18 and the tire mold pattern block are arranged in a horizontal direction. The side cross-sections of the pattern blocks have the same shape. In addition, when the L-shaped plate 27 rotates with the turntable 5 as the center, it will contact the second ramp block 26 and cause the second ramp block 26 to move horizontally. The horizontal movement of the second ramp block 26 drives the telescopic end of the third spring rod 16 to move. The movement of the telescopic end of the third spring rod 16 drives the rack 17 to move. At this time, the rack 17 and the gear 24 are no longer engaged, and the torsion force generated by the torsion spring 23 drives the shaft rod 22 to rotate ninety degrees in the opposite direction. The reverse rotation of the shaft rod 22 drives the electromagnet plate 4 and the tire mold pattern block to rotate ninety degrees, so that the tire mold pattern block can be cleaned longitudinally, and then the conveyor belt 1 is started to drive the tire mold pattern block to be transported. Further, the tire mold pattern block can be cleaned longitudinally during transportation. After the cleaning of the pattern block is completed, the drive motor 3 is rotated in the opposite direction to drive the turntable 5 and the components thereon to reset. In summary, it can be seen that the tire mold pattern blocks can be continuously cleaned horizontally and vertically by reciprocating in sequence, and multiple laser heads 11 are at the same distance from the tire mold pattern blocks during horizontal or vertical cleaning, which ensures the cleaning effect and avoids the situation where the laser head 11 is at different distances from the pattern blocks during cleaning, resulting in uneven cleaning quality, thereby improving the use effect of the equipment.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
