Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to a finishing and trimming machine for cold-rolled strip steel processing. Background Art

[0002] At present, a Chinese utility model with announcement number CN216991208U discloses a trimming machine with a noise reduction structure for cold-rolled strip processing, comprising a chassis main body, a debris baffle, a debris recovery trough, a debris recovery guide trough and a debris recovery pull box, wherein the upper surface of the chassis main body is provided with a debris baffle, and the debris baffle is fixedly connected to the chassis main body, the side of the debris baffle is provided with a debris recovery trough, and the bottom of the debris recovery trough is provided with a debris recovery guide trough; through structural improvement, and the arrangement and installation of a debris recovery trough, a debris baffle and a debris recovery pull box, when the device is trimming the strip, it can avoid the debris generated by the trimming falling on the surface of the chassis main body, so that the staff does not need to clean the surface of the chassis main body from time to time, and avoid the debris affecting the operation of the device, so that the actual use effect of the trimming machine with a noise reduction structure for cold-rolled strip processing is better.

[0003] Although the existing trimming machines are convenient for recycling debris and reduce the frequency of cleaning the table, there are still other problems during use. For example, they do not have a guiding and pressing function. The strip at the tail end is in a tension-free and non-pressurized state when winding. The strip is prone to loosening when winding, which has a certain impact on the quality of the strip. In addition, they do not have a dust collection and purification function. When the strip is trimmed by a grinding wheel, not only debris but also light dust and particulate matter will be generated. If the dust is inhaled by people during the dispersion process, it will pose a threat to health. The practicality is relatively low. In order to solve the above-mentioned problems, we propose a finishing trimming machine for cold-rolled strip processing. Utility Model Content

[0026] 1. The utility model first puts the steel strip on the winding roller on the left side, then pulls out one end of the steel strip and winds it around the winding roller on the right side. As the steel strip becomes thicker, it will push against the pressure roller to move it upward. When the pressure roller and the third fixed frame move upward, they will squeeze the fixed spring. When the fixed spring contracts, it will generate a rebound force, thereby prompting the pressure roller to press the steel strip tightly. It can have a guiding and pressing function, avoid the steel strip from being loosened when it is wound, and ensure the tightness of the steel strip after winding.

[0027] 2. The utility model starts the fan, which will rotate the internal impeller.
