Description

  The present invention relates to a detachable nozzle, and more particularly to a detachable nozzle for a sewing machine dust suction device.

  A conventional sewing machine is generally provided with a cloth waste guide device on a work table, and the cloth waste guide device collects cloth waste, yarn, and the like sucked into the suction port into a collection bag via a tube. . Such a cloth waste guide device collects cloth waste or thread sucked into the suction port, and after sewing work is finished, cloth waste or thread around the sewing machine that could not be collected due to high-pressure airflow. Blow off and clean with scissors. When a high-pressure air current is being jetted, cloth waste and yarn are blown off and dispersed in the air, so that the worker cannot breathe normally. In particular, in a factory having several tens of sewing machines, there is a problem that the air environment is further deteriorated when these sewing machines are cleaned simultaneously.

  In order to solve the above problems, a sewing machine waste suction device capable of sucking cloth wastes, threads and the like during the sewing process has been proposed. For example, “Disposable cloth edge guide device for sewing machine” described in Taiwan Patent 332686 of Patent Document 1 has been proposed. As shown in FIG. 2 of Patent Document 1, such a waste cloth edge guide device for a sewing machine is arranged such that the suction port of the air suction tube faces the front right rear side of the cloth edge cutting device. At the upper right of the front of the cloth edge cutting device, an air blowing tube is provided at a distance, and the air blowing port at one end of the air blowing tube is directed to the cloth edge cutting device, so that it is cut during the sewing process. The cloth edge is pushed by the air from the blowout port, moves to the suction port of the air suction tube, and is sucked into the suction port. Then, the air suction tube can effectively suck the cloth edge cut during the sewing process by an appropriate suction force, and noise generated when air is sucked can be reduced.

  However, cloths of various weights and thicknesses are used in the sewing process. In this case, if the air suction tube having a larger diameter sucks in heavy and thick cloth waste, and the air suction tube having a smaller diameter sucks light and thin cloth waste, the cloth waste suction operation becomes convenient. . Since the air suction tube of the above-mentioned Patent Document 1 is integrally formed, if it is desired to replace the air suction tube having a different diameter, it is necessary to replace the entire air suction tube. Since it is also necessary to adjust the air pressure after replacement, the operation is extremely inconvenient.
