Technical Field

[0001] The utility model relates to the technical field of needle punching machine cooling, in particular to a needle punching machine cooling device. Background Art

[0002] A needle punching machine is a blanket forming device that compacts and needles a refractory fiber blanket blank with a certain thickness to form a refractory fiber blanket. During the process of the needles in the needle punching machine frequently and repeatedly puncturing the refractory fiber blanket blank, when puncturing quickly, due to frictional heat generation, the surface temperature of the needles increases. Therefore, a cooling device is needed to cool the needles.

[0003] The cooling device includes a water pump, a water tank, cooling pipes, etc. When the needle punching machine starts to work, each component generates heat. To avoid equipment damage caused by excessive temperature, timely cooling is required. The coolant is pumped into the cooling system by the water pump, circulates along the pipes, takes away the heat of the heating components, and then returns to the water tank for recycling.

[0004] During the cooling process of the existing cooling device for the needle punching machine, the needles in the needle punching machine frequently and repeatedly puncture the refractory fiber blanket blank with a certain thickness. Due to frictional heat generation, the temperature of the needles increases. Since the needles cannot be quickly cooled, the cooling effect is poor. Therefore, a needle punching machine cooling device is proposed to solve the above problems. Content of the Utility Model

A water inlet pipe 6 and a water outlet pipe 7 are installed on the fixed plate 3. A plate groove 8 is opened on the side wall of the machine body 1. A sliding groove 9 is opened on the inner wall of the plate groove 8. A slider 10 is assembled in the sliding groove 9. A blowing plate 11 is installed on the slider 10. A cavity is opened inside the blowing plate 11. Multiple groups of air blowing pipes 12 are installed on the blowing plate 11. A connecting plate 23 is installed between the blowing plate 11 and the fixed plate 3. A guide air pipe 13 is connected to the blowing plate 11. A fan 14 is installed on the rear wall of the machine body 1 through a machine base. A guide air plate 15 is installed on the rear wall of the machine body 1. The guide air plate 15 is connected to the fan 14. The guide air pipe 13 is connected to the guide air plate 15. An air cavity 16 is opened inside the guide air plate 15. A round hole is opened on the guide air plate 15. A cooling pipe 17 is connected to the guide air plate 15 at the position of the round hole. A guide air cavity 18 is opened inside the cooling pipe 17. Exhaust holes 19 are opened on the inner wall of the cooling pipe 17. The water outlet pipe 7 penetrates through the cooling pipe 17. The other end of the water outlet pipe 7 is connected to a water tank 20. The water tank 20 is connected to the rear wall of the machine body 1. A water pump 21 is installed on the water tank 20 through a machine base. One end of the water pump 21 is connected to the water inlet pipe 6. The other end of the water pump 21 is connected to a guide water pipe 22. The other end of the guide water pipe 22 is connected to the water tank 20; during operation, in the process of cooling the needle punching machine by the existing cooling device, the needles 5 in the needle punching machine repeatedly puncture the refractory fiber blanket blank of a certain thickness frequently. Due to heat generated by friction, the temperature of the needles 5 rises. Since the needles 5 cannot be cooled quickly, the cooling effect is poor. By operating the fan 14, the fan 14 blows cold air into the guide air plate 15, and then the cold air is guided into the guide air pipe 13, and then into the blowing plate 11, and finally blown out from the air blowing pipes 12. Since the blowing plate 11 is parallel to the needles 5, during the needle punching process of the needles 5, the hydraulic rod 2 drives the fixed plate 3 to reciprocate vertically, the fixed plate 3 drives the needles 5 to reciprocate vertically, and at the same time the fixed plate 3 drives the connecting plate 23 to reciprocate vertically, and the connecting plate 23 drives the blowing plate 11, that is, the blowing plate 11 moves synchronously with the needles 5, so that the blowing plate 11 always faces the needles 5, and the cold air blown out from the air blowing pipes 12 always faces the needles 5, realizing the cooling of the needles 5;

[0019] By operating the water pump 21, the cooling water in the water tank 20 is guided into the water cooling groove 4 of the fixed plate 3 from the water inlet pipe 6, and the cooling water cools the needles 5 in the water cooling groove 4, realizing the secondary cooling of the needles 5;

[0020] After that, the cooling water flows back into the water tank 20 from the water outlet pipe 7. During the process of flowing through the water outlet pipe 7, the cold air in the air guiding plate 15 is guided into the air guiding cavity 18 and then blown out from the air exhaust hole 19. The cold air continuously cools the cooling water in the water outlet pipe 7, realizing the cooling of the cooling water. Then, the cooled cooling water flows back into the water tank 20, realizing the recycling of the cooling water. This structure double-cools the needle 5, which is beneficial to improving the cooling effect.

[0021] Working principle: During the process of cooling the needle punching machine by the existing cooling device, the needle 5 in the needle punching machine frequently and repeatedly punctures the refractory fiber blanket blank with a certain thickness. Due to heat generated by friction, the temperature of the needle 5 rises. Since the needle 5 cannot be quickly cooled, the cooling effect is poor. Through the operation of the fan 14, the fan 14 blows cold air into the air guiding plate 15. Then, the cold air is guided into the air guiding pipe 13 and then into the air blowing plate 11, and finally blown out from the air blowing pipe 12. Since the air blowing plate 11 is parallel to the needle 5, during the process of the needle 5 punching, the hydraulic rod 2 drives the fixing plate 3 to reciprocate vertically. The fixing plate 3 drives the needle 5 to reciprocate vertically. At the same time, the fixing plate 3 drives the connecting plate 23 to reciprocate vertically. The connecting plate 23 drives the air blowing plate 11, that is, the air blowing plate 11 moves synchronously with the needle 5, so that the air blowing plate 11 always faces the needle 5, and the cold air blown out from the air blowing pipe 12 always faces the needle 5, realizing the cooling of the needle 5; Through the operation of the water pump 21, the cooling water in the water tank 20 is guided into the water cooling groove 4 of the fixing plate 3 from the water inlet pipe 6, and the cooling water cools the needle 5 in the water cooling groove 4, realizing the secondary cooling of the needle 5; After that, the cooling water flows back into the water tank 20 from the water outlet pipe 7. During the process of flowing through the water outlet pipe 7, the cold air in the air guiding plate 15 is guided into the air guiding cavity 18 and then blown out from the air exhaust hole 19. The cold air continuously cools the cooling water in the water outlet pipe 7, realizing the cooling of the cooling water. Then, the cooled cooling water flows back into the water tank 20, realizing the recycling of the cooling water. This structure double-cools the needle 5, which is beneficial to improving the cooling effect.
