Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically relating to a surface grinder for processing graphite molds with dust-collecting effect. Background Technology

[0002] Surface grinders for graphite mold processing with dust extraction capabilities play an important role in industrial production and environmental protection. The dust extraction system can promptly remove graphite dust generated during processing, preventing dust from adhering to the workpiece surface or entering the machine tool, thereby ensuring processing accuracy and surface quality. The efficient dust extraction system can significantly reduce the concentration of suspended dust in the air and protect operators from the risk of long-term dust inhalation.

[0003] Some existing surface grinders for processing graphite molds with dust-collecting capabilities typically use a suction fan to directly draw graphite dust into an internal dust collection bag. This can cause graphite dust to enter the suction fan's interior. Graphite is a good conductor of electricity, and the accumulation of its dust on the suction fan's circuit board, terminals, or other electrical components can cause short circuits. This can not only affect the normal operation of the suction fan but also damage electronic components and even cause a fire. Utility Model Content

[0024] Embodiment

[0025] Refer to Figures 1-4 For the embodiment of the utility model, the embodiment provides a graphite mold processing flat grinding machine with dust suction effect, which can prevent graphite dust from entering the inside of the air suction fan 201, prevent the impurity grid 206 from being blocked by dust, and avoid excessive wear of the impurity grid 206.

[0026] The polishing mechanism 100 comprises a grinding machine body 101, and a rotating grinding wheel 102 and a workpiece tray 103 respectively adapted and installed on the surfaces of the two sides of the grinding machine body 101.

[0027] It should be noted that the rotating grinding wheel 102 is used for polishing the workpiece, and the workpiece tray 103 is used for placing the workpiece to be processed.

[0028] The dust suction mechanism 200 comprises a suction fan 201 arranged outside the grinding machine body 101, an air outlet 202 communicated below the suction fan 201, an air suction port 203 communicated in the cavity of the suction fan 201, a dust collection box 204 communicated at the other end of the air suction port 203, an air flow grille 205 fixedly installed on the outer surface of the dust collection box 204, an impurity grille 206 fixedly connected to the inner wall of the dust collection box 204, a driving assembly 207 cooperating with the suction force of the suction fan 201 to generate rotary power, and a anti-blocking assembly 208 cooperating with the rotary power of the driving assembly 207 to prevent the impurity grille 206 from being blocked.

[0029] It should be noted that the suction fan 201 can introduce the dust generated in the polishing process into the dust collection box 204 through the suction force generated thereby and the cooperation with the air suction port 203, the air flow grille 205 is used for preliminarily filtering large-particle dust, and the impurity grille 206 is used for further filtering and collecting fine dust to prevent graphite dust from entering the inside of the suction fan 201.

[0030] Specifically, the driving assembly 207 comprises a fixed block 207a fixedly connected to the inner wall of the dust collection box 204, a connecting shaft 207b fixedly installed on the inner surface of the fixed block 207a through a bearing sleeve, an impeller 207c fixedly installed on the outer end surface of the connecting shaft 207b, and a first pulley 207d fixedly sleeved on the outer surface of the connecting shaft 207b.

[0031] Further, the suction force generated by the suction fan 201 can drive the impeller 207c to rotate, and the connecting shaft 207b and the first pulley 207d are synchronously rotated by the impeller 207c.

[0032] Further, the driving assembly 207 further comprises a belt 207e sleeved on the outer surface of the first pulley 207d, and a second pulley 207f sleeved on the inner surface of the other end of the belt 207e.

[0033] Preferably, the driving assembly 207 further comprises a transmission column 207g fixedly connected to the inner surface of the second pulley 207f, and a rotating rod 207h fixedly connected to the outer surface of the transmission column 207g.

[0034] The first pulley 207d and the belt 207e can drive the second pulley 207f, the transmission column 207g and the rotating rod 207h to rotate.

[0035] It should be noted that the anti-blocking assembly 208 comprises a swing rod 208a hinged to the outer end surface of the rotating rod 207h, a sector block 208b hinged to the other end of the swing rod 208a, an arc-shaped rack 208c slidingly sleeved on the outer surface of the sector block 208b, and a gear 208d engaged with the outer surface of the arc-shaped rack 208c.

[0036] It should be explained that the rotation of the rotating rod 207h drives the swing rod 208a to swing through the hinge point, and the sector block 208b is driven to swing by the other end of the swing rod 208a. When the sector block 208b swings to the end thereof and contacts the end of the arc-shaped rack 208c, the sector block 208b continues to swing to push the arc-shaped rack 208c to reciprocate with the fixed column 208g as the center. The intermittent rotation of the gear 208d is realized by the reciprocating swing of the arc-shaped rack 208c. Each time the arc-shaped rack 208c swings, the gear 208d will rotate by a certain angle and then stop, waiting for the next swing.

[0037] Further, the anti-blocking assembly 208 further comprises a support shaft 208e fixedly connected to the inner surface of the gear 208d, a scraper 208f fixedly sleeved on the outer surface of the support shaft 208e and matched with the impurity grid 206, and a fixed column 208g fixedly connected to the inner wall of the dust collecting box 204 and matched with the sector block 208b.

[0038] Specifically, the outer end surfaces of the transmission column 207g and the support shaft 208e are fixedly installed on the inner wall of the dust collecting box 204 through bearings, and the inner surface of the sector block 208b is in rotating contact with the outer surface of the fixed column 208g.

[0039] In use, the air suction fan 201 is turned on, and the dust generated during the grinding process is introduced into the dust collecting box 204 through the cooperation of the suction force generated thereby and the air inlet 203, and the large-particle dust is preliminarily filtered through the airflow grid 205, and the fine dust is further filtered and collected through the impurity grid 206, so as to prevent the graphite dust from entering the interior of the air suction fan 201.

[0040] The suction force generated by the suction fan 201 during operation drives the impeller 207c to rotate, which in turn drives the connecting shaft 207b and the first pulley 207d to rotate synchronously, and through the cooperation of the first pulley 207d and the belt 207e, the second pulley 207f, the transmission column 207g and the rotating rod 207h are driven to rotate, the rotation of the rotating rod 207h drives the swing rod 208a to swing through the hinge point, and the other end of the swing rod 208a drives the sector block 208b to swing, when the sector block 208b swings to the end and contacts the end of the arc-shaped rack 208c, the sector block 208b continues to swing and pushes the arc-shaped rack 208c to reciprocate with the fixed column 208g as the center, through the reciprocating swing of the arc-shaped rack 208c, the gear 208d rotates intermittently, each time the arc-shaped rack 208c swings, the gear 208d rotates by a certain angle and then stops, waiting for the next swing, so as to realize the effect of intermittently sweeping the graphite dust on the surface of the impurity grid 206 by the scraper 208f driven by the gear 208d through the support shaft 208e.

[0041] In summary, through the dust collection mechanism 200, the graphite dust can be sucked into the dust collection box 204, which not only avoids the dust adhering to the surface of the workpiece or entering the machine tool, but also prevents the graphite dust from entering the suction fan 201, through the cooperation of the driving assembly 207 and the anti-blocking assembly 208, the suction force of the suction fan 201 can be used to intermittently sweep the graphite dust adhering to the surface of the impurity grid 206, so as to realize the effect of ensuring that the suction fan 201 can effectively suck the graphite dust into the dust collection box 204, while avoiding excessive wear of the impurity grid 206.
