[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5, an embodiment provided by the utility model:

[0022] A punching hollow needle for carrier tape production: comprises a hollow needle body 1, a mold 2 is fixedly connected to the surface of the hollow needle body 1, an air pipe 3 is fixedly connected to the surface of the mold 2, an end of the air pipe 3 away from the mold 2 is fixedly connected to an air pump 4, the air pump 4 is fixedly connected to the surface of the hollow needle body 1, an electromagnetic valve 5 is arranged on the surface of the air pipe 3, an external threaded tube 6 is arranged on the lower surface of the hollow needle body 1, a nut 7 is threadedly connected to the surface of the external threaded tube 6, a conduit 8 is fixedly connected to the bottom of the nut 7, a needle 9 is fixedly connected to the bottom of the conduit 8, the air needle can punch out the granular waste at the head of the hollow needle body 1, so that the stamping process of the hollow needle body 1 reaches a perfect state, but during the stamping process, the head of the hollow needle body 1 will block the air hole of the hollow needle body 1 due to wear and the like, so that the granular waste cannot be punched out, and the needle 9 is loaded on the hollow needle body 1 to replace the head of the hollow needle body 1 for stamping, so that the needle 9 is convenient for regular replacement.

[0023] Furthermore, a circular hole is opened on the surface of the mold 2, and an air hole is opened on the hollow needle body 1. The air hole of the mold 2 is connected to the circular hole of the mold 2. The diameters of the circular hole of the mold 2 and the air hole of the hollow needle body 1 are the same, which facilitates the connection between the circular hole of the mold 2 and the air hole of the hollow needle body 1.

[0024] Furthermore, one end of the air tube 3 is fixedly connected to the circular hole of the mold 2, and the other end of the air tube 3 is fixedly connected to the output end of the air pump 4. The air tube 3 transports the gas to the circular hole of the mold 2, and the gas enters the air hole of the hollow needle body 1 from the circular hole of the mold 2.

[0025] Furthermore, the hollow needle body 1 is connected to the air pipe 3 through the circular hole of the mold 2, and the air pump 4 outputs the gas to the air hole of the hollow needle body 1 through the air pipe 3. The hollow needle body 1 sprays out the gas, which will spray out the granular waste at the head of the hollow needle body 1, thereby ensuring the cleanliness of the head of the hollow needle body 1 during the stamping process.

[0026] Furthermore, the solenoid valve 5 controls the outflow and outflow amount of the gas inside the trachea 3 on the trachea 3. During the stamping process of the hollow needle body 1, the solenoid valve 5 controls the trachea 3 to deflate the hollow needle body 1, and controls the deflated amount of the trachea 3, to ensure that the gas entering the pores of the hollow needle body 1 through the trachea 3 can flush out the granular waste at the head of the hollow needle body 1.

[0027] Furthermore, the catheter 8 and the needle 9 are installed on the external threaded tube 6 through the nut 7. The catheter 8 is trumpet-shaped. The gas in the pore of the hollow needle body 1 will enter the needle 9 through the catheter 8. The needle 9 replaces the head of the hollow needle body 1 through the external threaded tube 6, the nut 7 and the catheter 8.

[0028] Furthermore, air holes are opened on the surface of the needle 9, and the air holes of the needle 9 are connected to the air holes of the hollow needle body 1 through the conduit 8. The gas of the hollow needle body 1 enters the needle 9 through the conduit 8, and the granular waste on the surface of the needle 9 will be flushed out.

[0029] Working principle: During the stamping process of the hollow needle body 1, the hollow needle body 1 will be stamped through the needle 9 at the bottom of the hollow needle body 1 to avoid damage to the air holes at the head of the hollow needle body 1. At this time, the air pump 4 will transport the gas to the air pipe 3. The solenoid valve 5 on the air pipe 3 controls the opening of the air pipe 3. The air pipe 3 transports the gas to the air holes of the hollow needle body 1 through the mold 2. The hollow needle body 1 transports the gas to the needle 9 through the conduit 8. The gas flushes out the granular waste on the needle 9 to ensure the stamping effect of the carrier. The needle 9 will block the air holes after long-term stamping. At this time, the nut 7 can be rotated on the external threaded tube 6 to remove the conduit 8 and the needle 9 from the head of the hollow needle body 1, and then replace it with the needle 9 that does not block the air hole for installation, so as to facilitate the replacement of the needle 9.
