A copper strip processing slitting machine with a dust blowing and heat dissipation function

Abstract

The present invention discloses a copper strip processing slitter with a dust blowing and heat dissipation function, which relates to the technical field of copper strip processing. Its structure includes a slitter main body, an inlet arranged at the bottom of the front end face of the slitter main body, and a U-shaped long bottom plate fixedly connected to the inlet at the bottom of the front end face of the slitter main body. When dust is generated during copper strip slitting, when the small motor is started to drive the blade to cut the copper strip, the toothed ring and the fan blade are synchronously driven to rotate. The fan blade drives the air inside the inlet into the inner side of the second inner cavity. By starting the water pump to make the spray head spray water, the dust in the air is brought into contact with the water, and then falls by gravity onto the inner side of the filter box for filtering and screening to collect the dust. At the same time, when heat is generated during the cutting of the copper strip, the surrounding air enters the second inner cavity and transfers heat by contacting the water, which can also achieve relative cooling. Synchronously, when it is necessary to adjust the width of the copper strip slitting, simply rotating the handle can quickly achieve simple operation.

Description

Technical Field

A C-shaped plate 24 is rotatably connected between the left side surface of the second bevel gear 19 and the outer side surface of the cylinder 22. A first bevel gear 25 is meshed and connected to the second bevel gear 19 and the third bevel gear 21. A first connecting column 26 is fixedly connected to the upper end surface of the first bevel gear 25.

The upper end surface of the screw rod 36 is fixedly connected to the rotating handle 6. A fan blade 37 is fixedly connected to the inner side of the toothed ring 12.

[0072] The working principle of this embodiment is:

[0073] When cutting the copper bar, dust is generated. When the first bevel gear 25 rotates, it drives the first connecting column 26 to relatively drive the short column 28 to rotate through the right-angle column 27. The connecting column drives the gear 30 to rotate and drives the long strip gear 31 to rotate, synchronously driving the toothed ring 12 to drive the fan blade 37 to rotate. The rotation of the fan blade 37 drives the dust in the air inside the inlet 2 to enter the second inner cavity 9. Then, the water pump 16 is turned on to make its nozzle 15 spray water, so that the dust in the air inside the second inner cavity 9 comes into contact with the water;

[0074] Subsequently, it falls inside the filter box 14 and is filtered and screened through the filter net provided at the bottom, leaving the dust inside the filter box 14. The water passes through the filter box 14 and falls into the inner bottom ends on the left and right sides of the second inner cavity 9. Subsequently, it is pumped through the connecting pipe by the water pump 16 and sprayed out from the spray head 15 for reuse. Then, the filter box 14 can be pulled out for collection and recycling. At the same time, when the heat generated during cutting is transferred to the surrounding air, the fan blade 37 drives the air to enter the second inner cavity 9 to take away the heat. Synchronously, through the water spray from the spray head 15, the heat in the air can also be absorbed relatively to achieve a cooling effect;

[0075] When it is necessary to adjust the width of the copper strip during slitting, by rotating the handle 6 forward or backward, the screw rod 36 is driven to rotate, driving the slider 35 to move up and down. At the same time, when the second connecting plate 34 pulls the first connecting plate 33 to move on the fixing plate 11, the arc plate 32 is driven. Blocked by the circular partition plate 29, the circular partition plate 29 is relatively driven to move, driving the short column 28 to move left or right. At this time, the gear 30 will slide on the long strip gear 31. At the same time, the short column 28 moves to drive the first connecting column 26 to move through the right-angle column 27. While driving the C-shaped plate 24 to move, the second bevel gear 19, the third bevel gear 21, the cylinder 22, and the blade 23 are synchronously driven to move on the outer side surface of the long rod 17, and it can also be quickly adjusted with simple operation.

[0076] Through improvement, the present invention provides a copper strip processing and slitting machine with a dust blowing and heat dissipation function. When dust is generated during copper strip slitting, by starting the small motor 10 to drive the blade 23 to cut the copper strip, the toothed ring 12 and the fan blade 37 are synchronously driven to rotate. The fan blade 37 drives the air inside the inlet 2 to enter the inner side of the second inner cavity 9. By starting the water pump 16 to make the spray head 15 spray water, the dust in the air comes into contact with the water and falls inside the filter box 14 for filtering and screening to collect the dust. At the same time, when temperature is generated during copper strip cutting, the surrounding air enters the second inner cavity 9 and transfers heat by contacting the water, which can also achieve relative cooling. Synchronously, when it is necessary to adjust the width of the copper strip slitting, just rotate the handle 6 to quickly achieve simple operation.

And the standard parts used in the present invention can all be purchased from the market.
