Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] like Figure 1-3 As shown, the vortex rod 1 mainly includes a vortex rod 1 and an air knife 2. The vortex rod 1 is mounted on the pick-and-place machine (not shown in the figure), and the air knife 2 is mounted on the guide groove where the feeder is located (not shown in the figure). The vortex rod 1 and the air knife 2 are connected by a connecting pipe 3, so that the vortex rod 1 can provide cold air to the air knife 2 to cool the feeder.

[0019] like Figure 2 As shown, the vortex rod 1 consists of a nozzle 11, a vortex chamber 12, and a hot end pipe 13 from one end to the other. A first air connector 14 is provided on the top of the vortex chamber 12. The first air connector 14 is connected to one end of the connecting pipe 3, and a regulating valve 15 is installed on the hot end pipe 13.

[0020] Preferably, the vortex rod 1 is mounted on a support plate 16, and the support plate 16 is fixedly mounted on the pick-and-place machine.

[0021] In a further preferred embodiment, a fixing plate 17 is also installed on the side of the support plate 16, through which the vortex rod 1 passes, thereby providing a more stable installation for the vortex rod 1.

[0022] like Figure 1 As shown, preferably, an outer cover 18 is also installed on the side of the support plate 16, and the hot end pipe 13 is located inside the outer cover 18. The outer cover 18 can isolate the hot end pipe 13 to a certain extent and prevent it from affecting the external environment and operators.

[0023] Standard 0.6 MPa gas from the workshop is introduced into nozzle 11. The vortex rod 1 expands and accelerates the high-pressure gas to the speed of sound. The gas forms a vortex in the vortex chamber 12, achieving hot and cold separation. The cold gas is then evenly output to the air knife 2 through the first gas connector 14 and connecting pipe 3. The proportion of hot gas entering the vortex rod 1 can be controlled by the regulating valve 15, which can also regulate the temperature and flow rate of the cold gas.

[0024] like Figure 3 As shown, the air knife 2 is a device that uses high-speed airflow for purging, drying, cooling, etc. The top of the air knife 2 is provided with a second air connector 21, which is connected to the other end of the connecting pipe 3, and the air outlet direction of the air knife 2 is towards the flyer.

[0025] Preferably, the air knife 2 is mounted on one end of a fixed frame 22, and the other end of the fixed frame 22 is mounted on the top of a vertical fixed shaft 25 via a fixed block 24. The bottom of the fixed shaft 25 is fixedly mounted on a fixed base 23, and the fixed base 23 is mounted on the guide rail groove where the feeder is located.

[0026] The cold air generated in the vortex rod 1 is introduced into the air knife 2 through the connecting pipe 3 and the second air connector 21, and can be blown out evenly from the air knife 2 towards the feeder to cool and dissipate heat.

[0027] This utility model provides a feeder refrigeration device, which has the following beneficial effects:
