DETAILED DESCRIPTION

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] The present application embodiment discloses a pneumatic discharge mechanism for a pellet press, referring to Figure 1 , including an air duct 2, one end of which is hinged on the side of the discharge barrel 1 away from the discharge port and connected to the inside of the discharge barrel 1, and the other end of the air duct 2 is externally connected to an air supply device (not shown in the figure), and the air duct 2 is provided with an adjustment component 3 for adjusting the air volume.

[0021] In the embodiment of the present application, the air supply device can be a blower. The air supply device can supply air to the discharge barrel 1 through the air duct 2 to speed up the discharge efficiency of the granular material at the discharge port, thereby improving the discharge effect of the device. Since the air duct 2 is hinged on one side of the discharge barrel 1, the wind direction of the gas can be adjusted by rotating the air duct 2. After the raw material processing is completed, the air duct 2 can be rotated to blow the inside of the discharge barrel 1 to discharge the residual granular material.

[0022] Specifically, a ball joint 4 is coaxially slidably sleeved on the outer wall of the air duct 2, a connecting hole is provided on the side wall of the discharge barrel 1, and a mounting seat 52 is bolted to the connecting hole on the side wall of the discharge barrel 1, and a mounting hole for accommodating the ball joint 4 is provided in the mounting seat 52, and the mounting hole is communicated with the connecting hole. The ball joint 4 is rotatably arranged in the mounting hole, and the air duct 2 is hinged to the connecting hole on the side wall of the discharge barrel 1 through the ball joint 4. A first stopper 5 for limiting the movement of the ball joint 4 is installed on the discharge barrel 1, and a second stopper 6 for limiting the sliding of the air duct 2 relative to itself is installed on the ball joint 4.

[0023] In the embodiment of the present application, the air duct 2 can not only rotate through the ball joint 4, but also slide into the inside of the discharge barrel 1. When the discharge port of the discharge barrel 1 is blocked, the air duct 2 is slid into the discharge barrel 1, which can not only improve the discharge effect with the help of wind power, but also rotate the air duct 2 to stir and clear the discharge port, further improving the discharge effect of the equipment.

[0024] Specifically, the first limiting member 5 includes a limiting bolt 51, and a threaded hole connected to the mounting hole is formed on the side wall of the mounting seat 52, and the limiting bolt 51 is threadedly connected in the threaded hole. During the raw material processing, the angle of the air duct 2 can be adjusted so that the air outlet is directly opposite to the discharge port of the discharge barrel 1, and then the limiting bolt 51 is tightened so that one end of the bolt abuts against the ball joint 4, so that the ball joint 4 can be limited from rotating. This prevents the air duct 2 from rotating due to wind or other external forces during the discharge process, thereby improving the stability of the discharge.

[0025] Reference Figure 2 The second stopper 6 includes an anti-slip ring 61. The ball joint 4 is provided with a through hole whose size matches the outer diameter of the air duct 2. The through hole is provided with an annular groove whose size matches the anti-slip ring 61. The anti-slip ring 61 is embedded in the annular groove on the through hole. The air duct 2 slides through the anti-slip ring 61 and contacts the inner wall of the anti-slip ring 61 by friction.

[0026] In the embodiment of the present application, the anti-slip ring 61 can be made of rubber. During the discharging process, the anti-slip ring 61 limits the air duct 2 from entering the inside of the discharging barrel 1 through friction; when the discharging port of the discharging barrel 1 is blocked, the staff can stop the press machine and then push the air duct 2 into the inside of the discharging barrel 1 to clear it.

[0027] Reference Figure 3 and Figure 4 The adjustment assembly 3 includes a connecting tube 31. A first baffle 21 is integrally fixed on the end surface of the end of the air duct 2 away from the discharge barrel 1. A plurality of ventilation holes 211 with different inner diameters are provided on the end surface of the first baffle 21 around its own axis. The connecting tube 31 is coaxially rotatably connected to the end of the air duct 2 away from the discharge barrel 1. A second baffle 32 is integrally fixed on the inner wall of the connecting tube 31, and the second baffle 32 is in sliding contact with the first baffle 21. A notch 321 is provided on the second baffle 32 for rotating with the connecting tube 31 to connect different ventilation holes 211. A soft connecting tube 7 is connected between the end of the connecting tube 31 away from the air duct 2 and the air supply device.

[0028] In the embodiment of the present application, the connecting tube 7 can be a soft air pipe. In order to prevent the connecting tube 31 from slipping off the air duct 2 and the connecting tube 7, one end of the connecting tube 31 can be fixedly connected to the connecting tube 7 by glue or a clamp or other tools, and the other end of the connecting tube 31 is provided with a groove on the tube wall, and mounting blocks are welded on both sides of the groove on the outer wall of the connecting tube 31, and the two mounting blocks are coaxially penetrated to provide limited holes. The connecting tube 31 is sleeved on the air duct 2, and then a bolt is passed through the two limited holes and a nut is threadedly connected. Tightening the bolt and the nut can drive the two mounting blocks to approach each other, so as to reduce the diameter of the tube mouth of the connecting tube 31 close to the air duct 2, so that the inner wall of the connecting tube 31 abuts against the outer wall of the air duct 2, so as to limit the connection tube 31 from being separated from the air outlet duct 2. Loosen the bolts and nuts on the connecting tube 31, and then manually rotate the connecting tube 31.

[0029] Since the discharge speed of the press machine is different under different working conditions, if the air volume of the air duct 2 is too large, it is easy to cause the granular material to splash from the discharge port, and if the air volume is too small, it is easy to cause low discharge efficiency, thereby blocking the discharge port. By rotating the connecting tube 31, the gap 321 can be connected to different ventilation holes 211, and the air volume of the air duct 2 can be adjusted to adapt to the discharge speed under different working conditions. Since the connecting tube 7 is fixedly connected to the connecting tube 31, the connecting tube 31 cannot be rotated too many times in the same direction.

[0030] In order to prevent the granular material from entering the air duct 2 and causing blockage, a filter screen 8 is installed at one end of the air duct 2 close to the discharge barrel 1.

[0031] The implementation principle of the pneumatic discharge mechanism for a pellet press in the embodiment of the present application is as follows: during the use of the pneumatic discharge mechanism for a pellet press, the air duct 2 delivers air into the discharge barrel 1, which can speed up the discharge efficiency of the pellets at the discharge port, thereby improving the discharge effect of the equipment. Since the air duct 2 is hinged to one side of the discharge barrel 1, the wind direction of the gas can be adjusted by rotating the air duct 2, so that after the raw material processing is completed, the air duct 2 can be rotated to purge the inside of the discharge barrel 1 to discharge the residual pellets. It has the advantage of improving the discharge effect.
