[0021] One embodiment of the present application is as follows: Figure 1 , Figure 3 and Figure 4As shown, the blowing and sucking component 2 is provided with a detection electric eye 3 at the inlet position, which is used to detect whether there is an empty load on the fixed jig in front of the blowing and sucking station. The blowing and sucking component 2 comprises a lifting mechanism 21 fixed on the rack table top of the filling line, the movable plate of the lifting mechanism 21 extends towards the side close to the conveying belt component 1 and is provided with a blowing and sucking head assembly 24, and the side of the movable plate away from the blowing and sucking head assembly 24 is provided with a suction pipe 25 connected with an external high-pressure air blower, which is provided with a filter screen to filter the back-sucked air and then discharge it. The blowing and sucking head assembly 24 is located directly above the bottle opening of the package material at the bottom blowing and sucking station, and the number of the blowing and sucking head assembly 24 and the number of the detection electric eye 3 match the number of the package material in a single fixed jig. The blowing and sucking head assembly 24 comprises a fixed pipe body 241 and a movable sleeve pipe 242 sleeved outside the fixed pipe body 241, and a return spring 247 is arranged between the inside of the movable sleeve pipe 242 and the fixed pipe body 241. An air inlet 2411 is formed in the side of the fixed pipe body 241 and is connected with a blowing pipe 246 arranged in the internal cavity of the fixed pipe body 241. A back-sucking pipe 245 corresponding to the top joint of the suction pipe 25 is arranged at the top of the fixed pipe body 241. The blowing and sucking head assembly is lowered into the package material by the air cylinder, clean air is blown in first to make the foreign matters float, and then the foreign matters are sucked away by vacuum, so as to ensure that the inside of the package material is not polluted, and the blowing and sucking head assembly can be directly applied in the conventional filling line without the need of changing the position of the package material, and the adaptability is high.

[0022] As shown in Figure 1 The lifting mechanism 21 comprises a center screw and a guide rod outside the center screw, a wire pipe is arranged in front of the center screw, the bottom plate of the lifting mechanism 21 is fixed on the rack table top, an adjusting hand wheel is arranged above the top plate and connected with the top of the center screw, the overall height of the blowing and sucking head assembly is manually adjusted, a lifting air cylinder 22 is vertically arranged on the side of the movable plate close to the blowing and sucking head assembly 24, and the output end of the lifting air cylinder 22 is connected with a mounting plate 23 for fixing the blowing and sucking head assembly 24.

[0023] As shown in Figure 2 The side of the lifting air cylinder 22 is provided with a stroke limiting mechanism 26, which comprises a fixed plate 261 fixed on the side of the lifting air cylinder 22, the fixed plate 261 is in an inverted F shape, and an upstroke limiting air cylinder 262 and a downstroke limiting air cylinder 263 are vertically arranged on the surface of two groups of transversely arranged short plates opposite to each other. The detection heads at the output ends of the upstroke limiting air cylinder 262 and the downstroke limiting air cylinder 263 are located between the two short plates, and the mounting plate 23 is arranged between the two groups of detection heads to set the upper and lower limits and ensure the mounting property of the blowing and sucking head assembly during the lifting and lowering process.

[0024] As shown in Figure 3 and Figure 4As shown, the movable sleeve 242 is sleeved outside the fixed tube body 241, and a sliding sleeve 243 is installed outside the bottom of the movable sleeve 242. The bottom of the sliding sleeve 243 is provided with a guide pipe 244, and the bottom of the guide pipe 244 is provided with symmetrically arranged back suction ports 2441.

[0025] The inner wall of the movable sleeve 242 is provided with a stepped section, and a reset spring 247 is installed between the stepped section and the bottom of the fixed tube body 241. When the sliding sleeve abuts against the bottle opening of the packaging material, the reset spring is compressed by external force. Since the fixed tube body is a fixed structure fixed on the mounting plate, the movable sleeve is subjected to external force and slides upward. The upper section of the movable sleeve 242 is symmetrically provided with vertically arranged waist-shaped grooves 2421, and the waist-shaped grooves 2421 are provided with limiting holes 2412 corresponding to the positions of the fixed tube body 241. A limiting pin 248 is sealingly installed in the limiting hole 2412, and is used to limit the sliding range of the movable sliding sleeve 242.

[0026] The air inlet 2411 is connected with an external filter, specifically a visual pipeline filter, which is used to filter objects with a size of 5-10 microns, so as to ensure the air quality of the cleaned packaging material. The blowing pipe 246 is coaxially installed with the fixed tube body 241 and the movable sliding sleeve 242. The bottom of the blowing pipe 246 penetrates through the guide pipe 244, and the outer diameter of the blowing pipe 246 is smaller than the inner diameter of the guide pipe 244. Figure 5 As shown, the bottom of the blowing pipe 246 is provided with an annular buffer 249, which abuts against the inner wall of the guide pipe 244. The buffer provides buffering during the movement of the movable sleeve, and blocks the internal space of the guide pipe during the blowing process of the blowing pipe and the silicon packaging material, so as to isolate the back suction channel and avoid interference.

[0027] The working principle of the embodiment is as follows: the conveying belt component drives the fixed jig to move, and the detection electric eye detects whether the surface of the fixed jig is empty. After the detection, the fixed jig moves to the blowing and sucking station. After the photoelectric switch detects the position, the lifting cylinder is lowered by a preset height, so that the guide pipe is inserted into the bottle opening of the packaging material. During the diving process, the sliding sleeve abuts against the bottle opening of the packaging material, and the reset spring is compressed under pressure, so as to drive the movable sleeve to move upward. After the lifting cylinder is dived to the position, the external gas is filtered by the filter, and then enters the packaging material through the blowing pipe. The blowing pipe is used to blow and clean the inner wall and bottom of the packaging material, so that the foreign matters are suspended. The blowing process is set by the electromagnetic valve, and the electromagnetic valve of the blowing pipe is closed after the blowing action is completed. The lifting cylinder continues to descend to the detection head position of the downstroke limiting cylinder. At this time, the annular buffer on the outer periphery of the blowing pipe extends out of the guide pipe, the back suction port is communicated with the inner cavity of the fixed tube body, the external high-pressure fan is used to suck the foreign matters in the packaging material, the lifting cylinder is reset after the back suction is completed, and one set of blowing and sucking operation is completed.

[0028] Need to explain a few points are: first, in the description of the present application, need to explain is, unless otherwise specified and limited, the term "installation", "connected", "connection" should be broad understanding, can be mechanical connection or electrical connection, but also can be two elements inside the communication, can be directly connected, "up", "down", "left", "right" and so on, only for indicating the relative position relationship, when the absolute position of the described object changes, the relative position relationship may change; second, in this paper, such as first and second and other relationship terms are only used to distinguish one entity from another entity, and do not necessarily require or imply that these entities have any such actual relationship or order.
