Description

Technical Field

[0001] The utility model relates to the technical field of cutter discs, in particular to a heat dissipation mechanism for double cutter discs. Background Art

[0002] Cutter discs are widely used in cutting fabrics. During operation, the cutter cuts the fabric at high speed, and the friction between the cutter and the fabric generates heat. In order to ensure the normal use of the cutter, the cutter needs to be heat-dissipated.

[0003] The existing heat dissipation mechanism of the double blade disc usually adopts an air cooling method, but air leakage and poor cooling effect may occur during the cooling process. Therefore, a heat dissipation mechanism of the double blade disc is proposed. Utility Model Content

[0004] The main purpose of the utility model is to provide a heat dissipation mechanism of a double-blade disc, which can effectively solve the problems in the background technology by arranging a first air inlet hole and a plurality of second air inlet holes to accelerate the flow of cooling gas.

[0005] To achieve the above-mentioned purpose, the utility model provides a double-cutting disc heat dissipation mechanism, comprising an inner cutter disc, a fixing block and an outer cutter disc;

[0006] The inner cutter disc is in a disc shape and is provided with a first air inlet hole and a plurality of second air inlet holes;

[0007] The fixed block is arranged in the inner cutter disc, and a cutter insertion hole is provided on the fixed block, and the cutter insertion hole is used to install the cutter. One side of the cutter insertion hole is connected to a first air inlet channel, and the first air inlet channel is arranged opposite to the first air inlet hole. The fixed block is also provided with a plurality of third air inlet holes, and the number of the plurality of third air inlet holes is the same as the number of the plurality of second air inlet holes. The third air inlet holes are connected to the corresponding second air inlet holes through a hose;

[0008] The outer cutter disc is rotatably mounted on the periphery of the inner cutter disc. A fourth air inlet hole is provided on the outer cutter disc. An annular air passage is provided between the outer cutter disc and the inner cutter disc. The annular air passage is used to connect the fourth air inlet hole with the first air inlet hole and multiple second air inlet holes.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, sealing rings are respectively provided on both sides of the annular air duct.

[0011] Furthermore, the first air inlet hole is connected to the first air inlet channel via an air inlet nozzle, and the air inlet nozzle is arranged in a strip shape on a side close to the first air inlet channel.

[0012] Furthermore, the number of the second air inlet holes and the third air inlet holes is three, and the three second air inlet holes are respectively connected to a hose on one side close to the fixing block, and the other end of the hose is inserted into the corresponding third air inlet hole.

[0013] Furthermore, a bearing is provided in the cutter insertion hole of the fixed block, and the cutter is installed through the bearing.

[0014] Furthermore, a fifth air inlet hole is provided on the outer cutter disc, and the fifth air inlet hole is a spare air inlet hole.

[0015] The beneficial effects of the present invention are as follows: the present invention provides a heat dissipation mechanism of a double-blade disc, which has the following advantages:

[0016] 1. The utility model is provided with a first air inlet hole and multiple second air inlet holes. After the cold air enters from the fourth air inlet hole, it is transported to the first air inlet hole and the second air inlet hole through the annular air duct, and is respectively sprayed onto the fixed block through the air inlet nozzle and the hose. Under the action of heat transfer, the cold air cools down the fixed block, and the temperature of the fixed block drops, thereby avoiding the occurrence of thermal deformation. The air that absorbs heat is discharged from the cutter socket, which greatly improves the heat dissipation efficiency of the heat dissipation mechanism and solves the problem that the existing heat dissipation mechanism has only one heat dissipation hole and low heat dissipation efficiency.

[0017] 2. The utility model sets an annular air duct and a sealing ring. The upper and lower sides of the annular air duct are respectively provided with sealing rings, which can ensure that the cooling air does not leak before cooling the fixed block. This solves the problem that the existing heat dissipation mechanism dissipates heat through cold air, but the cold air is prone to leakage during the heat dissipation process, thereby reducing the heat dissipation efficiency.

[0027] like Figure 1-3 As shown, the utility model provides a heat dissipation mechanism of a double cutter disc, comprising an inner cutter disc 1, a fixing block 2 and an outer cutter disc 9;

[0028] The inner cutter disc 1 is disc-shaped and is provided with a first air inlet 3 and a plurality of second air inlet holes 4;

[0029] The fixed block 2 is arranged in the inner cutter disc 1, and a cutter socket 5 is provided on the fixed block 2. A bearing is provided in the cutter socket 5, and the cutter is installed by the bearing. One side of the cutter socket 5 is connected to the first air inlet channel 6, and the first air inlet hole 3 is connected to the first air inlet channel 6 through an air inlet nozzle 13. The air inlet nozzle 13 is arranged in a strip shape on the side close to the first air inlet channel 6. A plurality of third air inlet holes 7 are also provided on the fixed block 2. The number of the plurality of third air inlet holes 7 is the same as the number of the plurality of second air inlet holes 4. The third air inlet holes 7 are connected to the corresponding second air inlet holes 4 through a hose 8;

[0030] The outer cutter disc 9 is rotatably mounted on the periphery of the inner cutter disc 1. A fourth air inlet hole 10 is formed on the outer cutter disc 9. An annular air passage 11 is provided between the outer cutter disc 9 and the inner cutter disc 1. The annular air passage 11 is used to connect the fourth air inlet hole 10 with the first air inlet hole 3 and the plurality of second air inlet holes 4. A sealing ring 12 is provided on both sides of the annular air passage 11.

[0031] In this embodiment, the number of the second air inlet holes 4 and the number of the third air inlet holes 7 are both three. The sides of the three second air inlet holes 4 close to the fixing block 2 are respectively connected to a hose 8, and the other ends of the hoses 8 are inserted into the corresponding third air inlet holes 7.

[0032] In this embodiment, the fourth air inlet 10 is connected to an external cooling compressed air device. The external cooling air enters the inner cutter head 1 and blows onto the fixed block 2, thereby cooling the fixed block 2. The temperature of the fixed block 2 decreases, thereby avoiding thermal deformation.

[0033] In this embodiment, the provision of the annular air channel 11 ensures that during the rotation of the inner cutter disc 1 and the outer cutter disc 9, cooling air can pass from the fourth air inlet hole 10 through the annular air channel 11 to the first air inlet hole 3 and the plurality of second air inlet holes 4, and then be blown onto the fixed block 2. Sealing rings 12 are provided on the upper and lower sides of the annular air channel 11, respectively, to ensure that the cooling air does not leak before cooling the fixed block 2, thereby solving the problem that the existing heat dissipation mechanism dissipates heat through cold air, but the cold air is prone to leakage during the heat dissipation process, thereby reducing the heat dissipation efficiency.

[0034] In this embodiment, cool air is simultaneously delivered through the first air inlet 3 with a large air volume and the plurality of second air inlet holes 4. Under the effect of heat transfer, the cool air reaching the fixed block 2 removes heat and is discharged from the cutter insertion hole 5, thereby greatly improving the heat dissipation efficiency of the heat dissipation mechanism and solving the problem of low heat dissipation efficiency of the existing heat dissipation mechanism due to only one heat dissipation hole.

[0035] Furthermore, the outer cutter disc 9 is provided with a fifth air inlet hole 14 , which is a spare air inlet hole.

[0036] Here’s how it works:

[0037] The fourth air inlet 10 is connected to an external cooling compressed air device. After the cold air enters from the fourth air inlet 10, it is transported to the first air inlet 3 and the second air inlet 4 through the annular air duct 11, and is sprayed onto the fixed block 2 through the air inlet nozzle 13 and the hose 8 respectively. Under the action of heat transfer, the cold air cools down the fixed block 2, and the temperature of the fixed block 2 drops, thereby avoiding thermal deformation. The air that absorbs heat is discharged from the cutter socket 5, which greatly improves the heat dissipation efficiency of the heat dissipation mechanism and solves the problem that the existing heat dissipation mechanism has only one heat dissipation hole and low heat dissipation efficiency. Sealing rings 12 are respectively provided on the upper and lower sides of the annular air duct 11, which can ensure the cooling air from leaking before cooling the fixed block 2, solving the problem that the existing heat dissipation mechanism dissipates heat through cold air, but during the heat dissipation process, the cold air is prone to leakage, thereby reducing the heat dissipation efficiency.

[0038] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
