Description

Technical Field

[0001] This utility model relates to the field of transmission and reception technology, and in particular to a ball-bearing transmission and reception module. Background Technology

[0002] In the field of paint spraying production, paint color changing mechanisms are crucial for achieving rapid switching between different paint colors and avoiding cross-contamination. The paint color changing ball transmitter and receiver module is the core functional component of this mechanism. This module is mainly used in automated spraying production lines. It moves a ball within the paint delivery pipeline, using the sealed connection between the ball and the pipeline wall to push out any remaining paint of the previous color. The receiver then collects the ball after the color change operation, preparing for the next cycle. Its operational stability directly affects paint color changing efficiency and the color accuracy of the sprayed products, making it widely applicable to various scenarios such as automotive painting, furniture spraying, and industrial equipment surface treatment.

[0003] The core equipment related to the paint color-changing roller ball transmitter and receiver module is the paint color-changing mechanism, which typically consists of a paint storage tank, a delivery pump, a color-changing valve assembly, a roller ball transmitter, a roller ball receiver, a spray gun, and a controller. Its working principle is as follows: Based on spraying requirements, the controller instructs the delivery pump to extract the specified color paint from the storage tank, which then enters the main delivery pipeline via the color-changing valve assembly. When a color change is needed, the controller activates the roller ball transmitter, using compressed air to push the roller ball into the pipeline. Driven by the airflow, the roller ball moves along the pipeline, scraping away residual paint from the inner wall and pushing it to the spray gun for discharge. When the roller ball reaches the end of the pipeline, the roller ball receiver captures it, and simultaneously, the color-changing valve assembly switches to the delivery channel for the new color paint. The new color paint enters the pipeline and completes the subsequent spraying operation, achieving rapid color switching.

[0004] In existing paint color-changing mechanisms, the ball bearing receiver, as a crucial link in ball bearing retrieval, generally suffers from insufficient buffering. Because the ball bearing is driven by compressed air within the pipeline, it maintains a high speed upon reaching the receiver. However, existing receivers typically only use a simple cavity structure to intercept the ball bearing, lacking an effective buffering mechanism. When the ball bearing impacts the receiver cavity wall at high speed, it easily causes scratches or deformation on the ball bearing surface, affecting subsequent sealing performance and reducing the ball bearing's lifespan. Furthermore, the high-speed impact generates significant impact noise, which does not meet workshop environmental protection requirements. It can also cause the receiver cavity to loosen, affecting the operational stability of the entire module and consequently negatively impacting paint color-changing efficiency and coating quality. Therefore, a ball bearing transmitting and receiving module is proposed to address these problems. Utility Model Content

[0037] Working principle: During the buffering process of receiving the color-changing ball 18, the receiving head 21 first receives the color-changing ball 18 and transmits the impact force to the slider 24 through the connecting rod 23. The impact force is buffered by the spring 3 25 and spring 20 at both ends. The anti-collision strip 26 between the buffer shell 22 and the receiving head 21 protects the receiving head 21 from strong impacts, which greatly reduces the impact force when the color-changing ball 18 reaches the receiving end. This solves the problem of the color-changing ball 18 having scratches, deformation or edge wear due to high-speed impact, which leads to a decrease in service life.

[0038] When installing or replacing the injection pump 1, first align the arc-shaped locking block 10 with the slot 11, rotate the injection pump 1 into the transmitter housing 2, and align the indicator marks 9 at both ends. At this time, under the reaction force of the spring 17, the inclined locking block 16 is engaged in the transmitter housing 2. Under the action of the sealing strip 12 and the sealing strip 23, a sealing effect is achieved, completing the installation of the injection pump 1. When disassembling, press the button 7, push the connecting block 14 and the limiting plate 15 to make the inclined locking block 16 retract into the injection pump 1. At this time, rotate the injection pump 1 to remove it. This optimizes the installation and disassembly process, avoids leakage caused by threaded connections, and solves the problem that the traditional technology of installing the injection pump 1 is prone to misalignment, which can lead to solvent leakage, contamination of the internal circuit of the module or other components, and cause malfunctions.
