How to Ensure Uniform Compression During the Truck - Jiangyin Aupu Machinery Co.,Ltd

Proper Tire Pretreatment and Orderly Placement

Before baling, truck tires must be pretreated to remove impurities such as metal wheels and stones. This prevents impurities from forming localized support during compression, which could lead to inadequate compression of surrounding tires.
Tires should also be sorted by size and thickness, with similar specifications grouped together to avoid mixing and stacking tires of varying sizes, which could cause uneven compression.
During feeding, the equipment's guide mechanism guides the tires neatly into the compression chamber, ensuring even distribution within the chamber without noticeable shifting or accumulation. This ensures uniform compression.

Adjust equipment compression parameters based on the tire's material characteristics, and appropriately set compression pressure and ram speed.
For truck tires with greater elasticity and thickness, a "gradual pressurization" mode can be used. Initially, a low pressure is applied to expel air from the tire, and then the pressure is gradually increased.
This avoids excessive pressure that can lead to over-compression in some areas while leaving others uncompacted. The speed of the indenter's descent is also adjusted to ensure smooth contact with the tire and even pressure transmission.
This prevents localized impact caused by excessive speed, which can affect compression uniformity.

Leveraging the synergistic effects of the equipment's compression mechanism, in addition to the vertical pressure provided by the main indenter, the side thrust mechanisms are activated to apply lateral pressure, squeezing the tire from multiple directions.
This eliminates gaps between tires and prevents uneven compression caused by unilateral force. Auxiliary pressure blocks, available on some models, can be used to apply additional pressure to loose areas such as tire edges and corners, ensuring uniform pressure across the tire.
Also, check the inner wall of the compression chamber for smoothness. Any wear or deformation should be repaired promptly to prevent bulges that hinder pressure transmission and affect compression effectiveness.

During the packaging process, the tire compression status should be monitored in real time through the equipment's observation window or monitoring system to check for uneven compression, such as localized bulges or depressions.
If any issues are detected, the equipment should be immediately paused to make adjustments—such as adjusting the tire's position within the cavity or fine-tuning the compression pressure or side thrust.
After completing a single compression cycle, the density and shape of the formed tire blocks should be checked. If any unevenness persists, the issue should be recorded and the parameters or placement of the next packaging cycle should be optimized accordingly.
Continuous monitoring and adjustment ensure uniform compression for each batch of tires.
