[0020] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0021] See Figure 1-Figure 2 , the utility model provides a technical solution:

[0022] Example:

[0023] like Figure 1 and Figure 2 As shown, a blowing device for producing medicinal glass bottles includes a transmission component 1 and a blowing pipe 2. The blowing pipe 2 is connected to an air source and can perform reciprocating linear motion along the vertical direction. The transmission component 1 is used to drive the blowing pipe 2 to move.

[0024] The transmission assembly 1 is in transmission connection with a driving member 3 of the bottle making machine, and the driving member 3 of the bottle making machine drives the blowing pipe 2 to move vertically through the transmission assembly 1 .

[0025] A vertical slide rail 4 is provided on the frame of the bottle making machine, and the air blowing pipe 2 is slidably connected to the slide rail 4 via a slider 5.

[0026] The driving member 3 of the bottle making machine is a motor.

[0027] The transmission assembly 1 includes a transmission rod 6, a connecting arm 7 and a driving wheel 8. The first end of the transmission rod 6 is hinged to the frame of the bottle making machine, the second end of the transmission rod 6 is hinged to the first end of the connecting arm 7, and the second end of the connecting arm 7 is hinged to the slider 5.

[0028] The driving wheel 8 is in driving connection with the driving member 3 of the bottle machine. A driving wheel 9 matching the driving wheel 8 is provided in the middle of the driving rod 6. The driving wheel 8 is a cam.

[0029] The cam cross section is fan-shaped.

[0030] The air blowing pipe is connected to the air source through a hose.

[0031] The air outlet end of the air blowing pipe 2 is provided with a tapered air nozzle 10. The diameter of the air nozzle 10 is smaller than the diameter of the bottle mouth.

[0032] 1. The drive element 3 (motor) of the bottle making machine in this embodiment is a motor that rotates the worktable supporting the (formed) glass bottles 11. 2. The bottle making machine may be, but is not limited to, a ZP-18 tube bottle making machine. Its specific structure and operating principle are prior art and will not be described in detail here.

[0033] Working principle: The transmission assembly 1 forms a connecting rod structure. When the driving member 3 (motor) of the bottle making machine rotates, it drives the driving wheel 8 to rotate. When the driving wheel 8 rotates, it drives the transmission rod 6 to rotate around the hinge point between the transmission rod 6 and the frame through the transmission wheel 9.

[0034] This causes the end of the transmission rod 6, which is away from the frame, to ascend or descend. This causes the transmission rod 6 to move the slide 5 vertically up or down along the slide rail 4, and the air blowing tube 2 on the slide 5 moves synchronously. As the air blowing tube 2 ascends, its nozzle 10 enters the bottle or reaches the bottle mouth. Once inside, the air blowing tube 2 blows air into the bottle, expelling any substances that may affect its water resistance.

[0035] When the driving member 3 rotates again, the blowing tube 2 moves downward, and the glass bottle 11 that has been blown enters the next station. When the next glass bottle 11 that has not been blown arrives just above the blowing tube, the blowing tube 2 just moves upward to the blowing position, and the above-mentioned action is repeated.

[0036] The utility model provides an air blowing device to blow air into the glass bottle after forming, thereby blowing out the substances in the bottle that affect the water resistance of the bottle to the outside of the bottle, so that the water resistance of the inner surface of the glass bottle can be controlled; at the same time, the air blowing device is driven by the automatic driving source of the bottle making machine, and there is no need to set up an additional driving mechanism, which greatly improves the utilization rate of the driving source.

[0037] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
