Description

[0032] Compared with the open processing in the first embodiment, the second embodiment sets a ceiling 601 on the top of the workbench 101, and sets a dust collection component on the workbench 101.

The dust collector 604 absorbs the dust in the ceiling 601 through the dust collection hood 607 connected thereto. At the same time, air curtain machines 603 are set corresponding to the two sets of transparent observation door panels 602. The air curtain machines 603 run stably and continuously blow out high-speed airflow to form a An air curtain with good barrier properties can prevent dust from escaping when the transparent observation door panel 602 is opened; it can not only improve the air quality in the workshop, reduce dust suspension, and reduce the risk of dust inhalation by operators, but also maintain the cleanliness of the surface of the workshop equipment, avoid dust adhesion and accumulation on the equipment, thereby reducing the probability of equipment failure caused by dust accumulation, and reducing the frequency and cost of equipment maintenance; in addition, the transparent observation door panel 602 provides the operator with a clear field of view, making it convenient to observe the grinding process, and the air curtain blown by the air curtain machine 603 will not interfere with the line of sight, which is beneficial for the operator to control the processing details and ensure the smooth progress of the grinding work.

[0033] Therefore, compared with open processing, such a dust collection component can improve the cleanliness and safety of the workshop environment, create a suitable working environment, and allow operators to devote themselves to production efficiently and attentively; thereby further optimizing the production process, reducing the extra working hours and manpower investment occupied by cleaning dust and maintaining equipment, improving overall production efficiency, and helping enterprises to achieve cost reduction and efficiency improvement and enhance market competitiveness; the remaining conditions are consistent with Example 1, so this example will not be repeated.

[0034] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
