Description

Technical Field

[0001] The utility model relates to the technical field of slitting circular knives, in particular to a slitting circular knife with good heat dissipation. Background Art

[0002] A slitting knife is a tool used to cut circular materials. It usually consists of a circular blade to cut large sheets of material into the required small size or shape.

[0003] After long-term use, the surface of the slitting circular knife will become hot, which will affect the slitting effect. At this time, it is necessary to stop the machine to allow the slitting circular knife to cool naturally, but the cooling speed of natural cooling is extremely slow, which can easily delay the work process.

[0004] Therefore, we propose a slitting circular knife with good heat dissipation to achieve the effect of rapid heat dissipation to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a slitting circular knife with good heat dissipation, which can achieve slow heating through a cooling groove to extend the working time of the slitting circular knife, and can quickly cool down after shutdown through a spray mechanism. The two cooperate with each other to achieve good heat dissipation.

[0006] To achieve the above object, the utility model provides the following technical solutions: a slitting circular knife with good heat dissipation, comprising a knife body, the knife body comprising a blade and a blade, the inner surface of the knife body is provided with four placement grooves, the inside of the knife body is provided with an annular cooling groove, the inside of the cooling groove is provided with a coolant, and the inner surface of the cooling groove is provided with a connection hole corresponding to the placement groove;

[0007] A liquid adding pipe and three gooseneck pipes are arranged inside the placement tank. The insides of the liquid adding pipe and the gooseneck pipes are communicated with the inside of the cooling tank through connecting holes. The front ends of the gooseneck pipes are connected with spray mechanisms.

[0008] Preferably, a mounting hole is provided in the center of the blade body.

[0009] Preferably, four ventilation holes are provided on the upper surface of the blade, and heat dissipation fins are fixedly mounted on both sides of the ventilation holes.

[0010] Preferably, a micro pump is installed inside the cooling tank, a mini valve is provided at the connection between the cooling tank and the gooseneck pipe, and nozzles are installed on both sides of the spray mechanism.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] (1) The utility model provides a circular slitting knife with good heat dissipation. When in use, a liquid-filling pipe is arranged in the uppermost placement groove. The staff can open the liquid-filling pipe to fill the cooling groove with coolant. After filling, the liquid-filling pipe can be closed through the end cover. At this time, the coolant in the cooling groove can slow down the temperature rise of the knife body during slitting, thereby achieving good heat dissipation performance, greatly extending the slitting time and increasing work efficiency.

[0013] (2) The utility model provides a circular slitting knife with good heat dissipation. When the knife body is stopped to dissipate heat naturally, the staff can pull up the gooseneck tube to adjust the spray position of the spray mechanism and the nozzle to put the nozzle into the spray state, and then drive the micro pump to open the mini valve. At this time, the micro pump will pump the coolant in the cooling tank into the spray mechanism, and the nozzle will spray it onto the surface of the knife body in the form of a spray. By setting two nozzles, the spraying area can be increased to comprehensively and quickly cool down the knife body, thereby accelerating the cooling time of the knife body, making it quickly enter the working state, and improving work efficiency.

[0021] Furthermore, a mounting hole 111 is provided at the center of the blade body 11. When in use, the blade body 1 is mounted on the shaft through the mounting hole 111, and can be rotated to facilitate the cutting operation.

[0022] Furthermore, four ventilation holes 112 are provided on the upper surface of the blade body 11, and heat dissipation fins 113 are fixedly installed on both sides of the ventilation holes 112. When in use, the heat dissipation effect can be further heated by adding ventilation holes 112 and heat dissipation fins 113, thereby slowing down the heating speed of the blade body 1 and extending the working time.

[0023] Furthermore, a micro pump is installed inside the cooling tank 3, a mini valve is provided at the connection between the cooling tank 3 and the gooseneck 4, and nozzles 42 are installed on both sides of the spray mechanism 41. When the blade 1 is shut down for natural heat dissipation, the staff can pull up the gooseneck 4 to adjust the spray position of the spray mechanism 41 and the nozzle 42 to make the nozzle 42 enter the spray state, and then drive the micro pump to open the mini valve.

[0024] Working principle: The utility model is a slitting circular knife with good heat dissipation. By placing the groove 2, the liquid adding pipe 21 can be easily opened and the gooseneck pipe 4 can be adjusted. When in use, the cooling liquid is added to the cooling groove 3 by opening the liquid adding pipe 21. The cooling liquid in the cooling groove 3 absorbs heat when the knife body 1 is slitting, which can effectively slow down the heating speed and improve the heat dissipation performance. The heat dissipation can be accelerated through the air holes 112 and the heat dissipation fins 113, and the heating speed of the knife body 1 can be further reduced. When the knife body 1 stops to dissipate heat naturally, the staff can adjust the position of the gooseneck pipe 4. The nozzle 42 is put into the spraying state, and then the micro pump is driven to open the mini valve. The micro pump pumps the coolant in the cooling tank 3 to the spray mechanism 41, and sprays it to the surface of the cutter body 1 in the form of a spray through the nozzles 42 on both sides, so as to achieve rapid and comprehensive cooling and heat dissipation. Through the above design, the cutter body 1 can effectively dissipate heat during the slitting process, extend the working time, improve the working efficiency, and actively accelerate the cooling through the spray mechanism 41 when the machine is stopped, so that the cutter body 1 can quickly resume the working state, thereby enriching the overall function and increasing the overall practicality.
