[0023] Two pairs of legs 5 are respectively arranged on both sides below the inner cylinder 6.3, and the two legs 5 in a pair are respectively located at the front and rear sides of the belt conveyor 4.

A distance sensor for detecting the height of the material loaded in the packaging bag is installed on the outer side wall at the bottom end of the inner cylinder 6.3.

[0025] The bag supporting and sealing integrated mechanism 7 includes a support plate 7.1, a strip 7.4 arranged horizontally on the inner side of the top of the support plate 7.1, a plurality of vacuum suction heads 7.5 arranged inside the strip 7.4, a hot melt bag sealing member 7.6 arranged parallel to the strip 7.4 below, and a telescopic cylinder two 7.2 and a telescopic cylinder three 7.3 with their piston cylinders fixed to the outer side of the support plate 7.1 and respectively corresponding to horizontally pushing and pulling the strip 7.4 and the hot melt bag sealing member 7.6. Among them, the vacuum suction head 7.5 includes a pipe body 7.5.1 sleeved on the middle of the support plate 7.1, a limit ring 7.5.6 fixedly sleeved on the pipe body 7.5.1 and fitting against the inner side wall of the support plate 7.1, an external thread 7.5.7 arranged on the outer peripheral wall of the outer end of the pipe body 7.5.1, a nut 7.5.8 threadedly sleeved on the external thread 7.5.7 and fitting against the outer side wall of the support plate 7.1, a spherical outer shell 5.2 fixedly docked to the inner end of the pipe body 7.5.1, a spherical inner shell 7.5.3 rotatably sleeved inside the spherical outer shell 5.2, a short pipe 7.5.4 fixedly docked to the port of the spherical inner shell 7.5.3, and a suction cup 7.5.5 fixed to the port of the short pipe 7.5.4. The outer end of the pipe body 7.5.1 is connected to a vacuum pump through a pipeline.

[0026] The swing mechanism 8 includes a support 8.1 fixed to the outer top end below the inner cylinder 6.3, a shaft rod 8.2 with its front and rear ends rotatably sleeved on the support 8.1, and a swing motor 8.3 for driving the shaft rod 8.2 to rotate.

[0027] The support groove 9 is arranged outside the swing mechanism 8 and is used for carrying the packaging bag. Among them, the support groove 9 includes a bracket 9.2 arranged outside the feeding section of the belt conveyor 4, and a trough body 9.1 whose outer end of the bottom surface is fixed to the top end of the bracket 9.2; guardrails 9.3 are respectively arranged vertically on the front and rear sides of the trough body 9.1.

[0028] Among them, the front and rear ends of the bottom of the support plate 7.1 of a bag-supporting and sealing integrated mechanism 7 are respectively fixed to the top of the support legs 5 inside the lower part of the inner cylinder 6.3, and the top end of the support plate 7.1 of the other bag-supporting and sealing integrated mechanism 7 is axially fixed to the shaft rod 8.2.

[0029] In summary, the powdery products of the metallurgical furnace are generally stored in the storage cylinder 1 first. The packaging bags are placed in the trough body 9.1 in a stacked manner, and the bag mouth direction of the packaging bags is ensured to face the direction of the storage cylinder. When packaging the powdery products, first, the swing motor 9.3 drives the shaft rod 8.2 to rotate clockwise by 90°. At this time, the bag-supporting and sealing integrated mechanism 7 corresponding to the swing mechanism 8 will rotate with the shaft rod 8.2, so that its suction cup 7.5.5 is exactly opposite to the bag mouth position of the packaging bag; the telescopic cylinder II 7.2 extends the telescopic rod, so that the suction cup 7.5.5 fits on the bag mouth position of the topmost packaging bag. Since the air pump makes the inner cavity of the suction cup 7.5.5 in a negative pressure state, the packaging bag is adsorbed.

[0030] The swing motor 9.3 then rotates counterclockwise by 90°. At this time, the suction cup 7.5.5 on the other side is exactly opposite to the other side of the bag mouth of the packaging bag, and its corresponding telescopic cylinder II 7.2 extends the telescopic rod to adsorb the two sides of the bag mouth of the packaging bag on the corresponding suction cups 7.5.5 respectively, and the telescopic cylinders II 7.2 on both sides retract the telescopic rods synchronously to open the bag mouth of the packaging bag.

[0031] The telescopic cylinder I 6.4 pushes the inner cylinder 6.3 downward, so that while the inner cylinder 6.3 is inserted into the bag mouth of the packaging bag, the material hole 6.3.1 is aligned with the discharge port of the screw conveyor mechanism 3.

[0032] The conveying motor 3.2 drives the screw blade shaft 3.1 to rotate to push the powdery products towards the direction of the pipe head II 2.4. The powdery products enter the inner cylinder 6.3 through the pipe head III 6.2 and the material hole 6.3.1 and are filled into the packaging bag. The distance sensor at the bottom of the inner cylinder 6.3 is used to judge whether the packaging bag is filled to the set height.

[0033] When the filling process is completed, the conveying motor 3.2 stops, and the telescopic cylinder I 6.4 retracts the telescopic rod to lift the inner cylinder 6.3.

[0034] At this time, the telescopic cylinders II 7.2 and III 7.3 on both sides simultaneously extend the telescopic rods, so that the bag opening of the packaging bag is closed, and the heat-sealing bag members 7.3 on both sides are clamped on both sides of the bag opening of the packaging bag, completing the sealing operation of the packaging bag. Release the adsorption of the suction cup 7.5.5 on the bag opening of the packaging bag, retract the telescopic cylinders II 7.2 and III 7.3 on both sides, and start the belt conveyor 4 to convey the powdered product that has been packaged away from the loading station, so as to facilitate the next cycle of loading and sealing processes.

[0035] Among them, by rotating the swing motor 8.3 and extending the piston rod of the outer telescopic cylinder II 7.2, the powdered product that has been packaged can be pushed down from the middle, so that the powdered product can smoothly pass through the lower side of the inner bag-supporting and sealing integrated mechanism 7 during transportation.

[0036] In order to improve the supporting effect on the spiral blade shaft 3.1, a shaft sleeve 2.7 that is rotatably sleeved on the outer end of the spiral blade shaft 3.1 is provided in the middle of the outer end of the inner cavity of the pipe head II 2.4, and a support rod 2.8 is fixed between the outer peripheral wall of the shaft sleeve 2.7 and the inner peripheral wall of the pipe head II 2.4.

[0037] In order to further ensure the smooth movement of the slat 7.4 and the heat-sealing bag member 7.6, guide rods 7.8 are respectively sleeved on the front and rear ends of the outer side wall of the slat 7.4 and the front and rear ends of the outer side wall of the heat-sealing bag member 7.6, and linear bearings 7.7 that are slidably sleeved and matched with the guide rods 7.8 are fixed on the side wall of the support plate 7.1.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
