Abstract
Description
Technical Field
[0001] This utility model relates to the field of sponge pad cutting technology, and in particular to a sponge pad cutting device for underwear. Background Technology
[0002] In the production of lingerie padding, vibratory cutting is a core process for achieving irregular shapes and precise dimensions. However, existing cutting devices commonly suffer from sponge particle contamination. During vibratory cutting, the sponge is subjected to high-frequency vibration impact, easily generating fine particles (especially low-density soft sponges). These particles are lightweight and easily dispersed, not only permeating the air in the production workshop and potentially irritating the respiratory tract and affecting the health of operators if inhaled, but also adhering to the surface of equipment transmission components (such as slide rails and lead screws), accelerating component wear and shortening equipment lifespan. Traditional devices lack targeted particle collection designs, requiring additional manpower to clean the dispersed sponge particles, increasing production steps and costs. Furthermore, untimely cleaning can easily cause secondary contamination, failing to meet the cleanliness, precision, and efficiency requirements of lingerie production. Therefore, there is an urgent need to develop a lingerie padding cutting device that uses a multi-directional precise adjustment mechanism for the vibratory knife to adapt to different cutting needs through forward, backward, left, right, and up / down movement, combined with a real-time dust collection mechanism consisting of a transparent acrylic isolation cover and a negative pressure vacuum cleaner to reduce sponge particle contamination. This would overcome the shortcomings of current practical applications and meet current needs. Utility Model Content

The left and right moving mechanism drives the base, the up and down moving mechanism, and the vibrating blade to move left and right, thereby adjusting the position of the vibrating blade. The up and down moving mechanism drives the vibrating blade to move up and down, so that the position of the vibrating blade can be adjusted in multiple directions, making it convenient for the vibrating blade to cut the sponge. During cutting, the second electric telescopic rod drives the isolation cover to move up and down, so that the isolation cover is attached to the upper surface of the sponge to cover the sponge particles generated during cutting. At the same time, the negative pressure vacuum cleaner sucks up the sponge particles at the nozzle and transports them to the dust collection hood of the negative pressure vacuum cleaner for collection, reducing pollution to the outside world. In summary, this utility model achieves multi-directional precise adjustment of the vibrating blade through a forward, backward, left, right, and up-down moving mechanism to adapt to different cutting needs, and reduces sponge particle pollution by combining a transparent acrylic isolation cover with a negative pressure vacuum cleaner.
