Description

Technical Field

[0001] The utility model relates to the technical field of roving blocking devices, and specifically relates to a roving blocking device for processing roving. Background Technique

[0002] The roving blocking device plays an important role in textile machinery, mainly used for cutting or blocking roving to ensure the smooth progress of the spinning process. For example, the Chinese patent discloses a roving blocking device for roving processing (authorization publication number CN218860976U). In this patented technology, by sliding the slider, the slider drives the concave slide to slide. In this way, the operator slides the concave slide to the side close to himself, then places the fiber filament inside the concave slide, and then pushes up the pressing plate. After placing the fiber filament under the pressing plate, the pressing plate is released. After the pressing plate presses the fiber filament, it slides through between the lower cutting knife and the upper cutting knife, and then the operator takes out the fiber filament. This operation improves safety and avoids the operator being injured by the upper cutting knife;

[0003] However, when the existing publicly disclosed roving blocking device is actually applied, there are still some defects that need to be improved. For example:

[0004] ① When cutting the roving by pressing down the cutting knife, the roving has a soft texture, and there is a problem that the roving cannot be cut, which is not conducive to the blocking effect of the roving blocking device;

[0005] ② When the roving passes through the roving blocking device, it rubs against the cutting position, causing relatively large wear to the roving and affecting the processing quality of the roving. Therefore, the technical personnel in this field provide a roving blocking device for processing roving to solve the problems raised in the above background technique. Content of the Utility Model
