[0027] Referring toFigure 7 As shown in the embodiment: the surface of the slide rod 24 is sleeved with a spring 27, the top end of the spring 27 is fixedly connected with the scraper 25, and the bottom end of the bearing plate 7 is fixedly connected with the surface of the support 4. The initial height of the scraper 25 is limited by the pull of the spring 27 on the scraper 25. When the scraper 25 is moved upward by the screw rod 26, the scraper 25 pulls the spring 27 to extend and store power. When the scraper 25 is not acted on by the screw rod 26 and is tightly attached to the conveying belt 6, the spring 27 will release the generated force to rebound and pull the scraper 25 to move downward, so that the scraper 25 moves away from the conveying belt 6 to adjust the height of the scraper 25.

[0028] Working Principle: The slide assembly 8 employs a three-axis slide gantry module, allowing adjustment of the XY axis positions and vertical height of the two lifting carrier plates 9. This enables real-time position adjustment of the welding head 10 at the top of the conveyor belt 6, resulting in more precise processing of plastic parts. The carrier plate 7, placed inside the conveyor belt 6, supports the top of the belt, ensuring surface flatness and further enhancing the welding accuracy of the welding head 10. Simultaneously, the conveyor belt 6 transports materials, allowing the two welding heads 10 to operate in a staggered manner, processing in separate areas. This enables bidirectional processing of the same weld seam by both welding heads 10, reducing the time required for significant position adjustments of the slide assembly 8 and further improving the welding accuracy of the welding head 10 on plastic parts. The welding head 10 utilizes ultrasonic spot welding technology to generate high-frequency vibrations that produce frictional heat, melting and cooling the plastic contact surface to solidify the weld, resulting in a strong and high-strength weld. This also reduces pollution and odor caused by plastic welding. Through the meshing connection between the drive motor 11 and the toothed plate 14, the rotational force of the drive motor 11 is converted into linear motion. This allows the drive motor 11 to move the toothed plate 14 up and down as it rotates in both directions. The copper sleeve 12 restricts the left and right position of the welding head 10. When the toothed plate 14 rises or falls, it drives the partition 13, causing the welding head 10 to slide up and down on the surface of the copper sleeve 12, achieving precise height control of the welding head 10. This, combined with the lifting and lowering of the slide assembly 8, allows for faster adjustment of the welding head 10's height, improving efficiency. The welding head 10 improves production efficiency during the welding process. The transfer port 15 allows for the installation of conveyor belts on both sides of the housing 1, connecting to the output and input ends of the conveyor belt 6. This facilitates material entry and exit, enhances the convenience of material transport by the conveyor belt 6, and increases the production capacity of the device. Multiple observation windows 16, made of tempered glass, allow light to pass through multiple sides of the housing 1, facilitating observation of the machine's internal operation. An operating light 17 connected to the programming computer 3 monitors the machine's operating status in real time and issues an alarm light when the machine malfunctions. The programming computer 3 controls the extension and retraction of the hydraulic rod 20, pushing the sliding plate 21 along an arc-shaped path as the hydraulic rod 20 extends. The trough 19 slides inside, and the arc-shaped trough 19 itself rotates at one end of the mounting shell 18 via a rotating shaft, causing the slide plate 21 to slide and push the extrusion roller 22 assembly downwards. This brings the surface of the extrusion roller 22 close to the inner diameter surface of the conveyor belt 6, pressing down on both ends of the conveyor belt 6, making the conveyor belt 6 tighter. This prevents the conveyor belt 6 from loosening after long-term use and failing to transport materials properly, thus reducing the machining accuracy of the welding head 10. By turning the screw 26 upwards, the operator pushes the scraper 25 upwards. At the same time, the scraper 25 drives the slide bar 24 to slide upwards along the inside of the extension plate 23. This restricts the movement trajectory of the scraper 25 with the slide bar 24 and the extension plate 23, ensuring the linear movement trajectory of the scraper 25. When the scraper 25 approaches the surface of the conveyor belt 6...The close contact of the scraper 25 with the conveying belt 6 during operation of the conveying belt 6 causes dirt on the surface of the conveying belt 6 to be scraped off by the scraper 25, thereby achieving the effect of cleaning the dirt on the surface of the conveying belt 6, maintaining the neatness of the surface of the conveying belt 6, preventing dirt accumulation from causing unevenness on the surface of the conveying belt 6 to affect the processing accuracy of the conveying belt 6, and preventing dirt from normally contaminating the conveyed material. The spring 27 holds the scraper 25, and limits the initial height of the scraper 25. When the scraper 25 is moved upward by the screw rod 26, the scraper 27 pulls the spring 27 to extend and store energy. When the scraper 25 is not acted on by the screw rod 26 and is close to the conveying belt 6, the spring 27 releases the generated force to rebound and pull the scraper 25 to move downward, so that the scraper 25 moves away from the conveying belt 6 to achieve adjustment of the height of the scraper 25.
