Description

Technical Field

[0001] The utility model relates to the technical field of buffer pad production, in particular to an edge sealing device for a sound-absorbing cotton damping buffer pad. Background Art

[0002] When used together, damping pads and sound insulation cotton can provide better sound insulation. Damping pads are mainly used to reduce the conduction of vibration and noise, while sound insulation cotton is used to absorb and reduce the transmission of sound waves. They play different roles and can be combined to reduce noise levels more effectively. The damping cushion is mainly made of rubber.

[0003] In the prior art, a Chinese patent with publication number "CN220331762U" discloses a buffer pad edge sealing device, which drives a pressure plate downward through a hydraulic cylinder, presses the buffer pad onto a boss through the pressure plate to prevent the buffer pad from moving, and then drives a transmission rod to rotate through a second motor, drives a first threaded sleeve and a second threaded sleeve to move toward each other through the transmission rod, drives two limit rods to move toward each other through the first threaded sleeve and the second threaded sleeve, and drives two electric heating rods to move toward each other through the two limit rods, so as to perform edge sealing processing on buffer pads of different sizes, so that the two electric heating rods are respectively fitted with the left and right sides of the buffer pad, and then the electric heating rods are started to iron out the burrs on the left and right sides of the buffer pad, thereby solving the problem of low work efficiency of existing workers using handheld tools to seal the edges of buffer pads to remove burrs.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] During the production process of buffer pads, large pieces of rubber need to be cut into buffer pads of appropriate sizes for use. However, since many burrs will appear on the edges of the buffer pads after cutting, which affects the quality of the buffer pads, a device is usually required to process the burrs on the buffer pads. Currently, most methods for processing the burrs on the edges of buffer pads are to perform edge processing through heating rods or grinding rollers. As described above, the burrs on the edges of the buffer pads are mainly ironed out through heating rods. However, since the burrs on the edges of the buffer pads are of different lengths, the heating rod cannot effectively iron out all the burrs during heating and ironing. Although the distance between the heating rod and the buffer pad can be adjusted, the buffer pad is easily burned when the distance is too close. Moreover, although the distance between the heating rod and the buffer pad can be adjusted back and forth, the position of the heating rod needs to be adjusted all the time, which is more troublesome.
