Description

Technical Field

[0001] This utility model relates to the field of foaming machine technology, specifically to an adjustable drop plate for a vertical foaming machine for sponges. Background Technology

[0002] Vertical foaming machines are the main equipment for producing block polyurethane foam. Their working principle involves mixing various chemical raw materials and pouring the mixture onto a continuously moving base paper. During this process, the materials undergo a chemical reaction and foam, ultimately forming continuous foam blocks. The drop plate is one of the key components of a vertical foaming machine, typically installed below the mixing head. Its function is to spread the mixed liquid material thinly and guide it to fall smoothly onto the base paper, forming a uniform curtain of material.

[0003] Most existing vertical foaming machines use fixed drop plates, whose height and tilt angle cannot be changed after installation. However, the required process parameters vary when producing sponge products with different densities, hardnesses, or widths. Fixed drop heights and angles cannot optimize the material spreading and falling process, potentially leading to uneven material distribution and inconsistent internal bubble structures. This directly affects the final quality and yield of the sponge products, limiting the equipment's process adaptability and flexibility.

[0004] Therefore, there is an urgent need for a drop plate with adjustable height and angle to meet the process requirements of diversified production. Utility Model Content

[0019] The working principle of this embodiment is as follows: By starting the motor, the first transmission rod rotates. Through the engagement of the first and second bevel gears, the first transmission rod drives the first sleeve to rotate. Since the first guide rod is slidably connected to the base frame, the rotation of the first sleeve causes the first screw to move up and down within the first sleeve. When the motor operates, the first transmission rod rotates, and the first bevel gears at both ends of the first transmission rod drive the fifth bevel gear at one end of the third transmission rod to rotate, thus driving the third transmission rod to rotate. The third transmission rod, through the engagement of the first and second transmission blocks, drives the fourth transmission rod to rotate. The fourth transmission rod, through the engagement of the sixth and third bevel gears, drives the second transmission rod to rotate. The second transmission rod, in turn, through the engagement of the third and fourth bevel gears, drives the second sleeve to rotate, thus driving the second screw to rotate. Since the second guide rod is slidably connected to the base frame, the rotation of the second sleeve causes the second screw to move up and down. In other words, by operating one motor, both first screws and both second screws can move simultaneously, ultimately driving the lifting seat and tilting plate to rise and fall, lifting the material. When the angle of the drop plate needs to be adjusted, the electric telescopic rod retracts, causing the third sleeve to slide along the fourth transmission rod, so that the first transmission block moves away from the second transmission block. At this time, when the motor rotates in the opposite direction, it will only drive the first screw to move downward, and will not drive the second screw to move, so that the flip plate rotates downward and the material on the flip plate falls into the foaming tank.

[0020] It should be noted that the first and second screws are of the same model, and the first and second sleeves are of the same model, all made from the same mold to improve synchronization.
