Description

Technical Field

[0001] The present invention relates to the technical field of powder packaging, in particular to a full-automatic powder packaging machine. Background Art

[0002] The powder packaging machine mainly includes a machine base, on which a hopper is installed, and a filling tube is provided at the bottom of the hopper. During filling, the mouth of the packaging bag used to hold the powder is generally opened manually to align it with the filling tube. Generally, in order to reduce the escape of powder, the mouth of the packaging bag is wrapped with the filling tube and tightened with elastic materials such as rubber bands (there will be a gap to facilitate gas outflow). At the same time, the packaging bag is placed on a weighing platform, and the powder is filled from the hopper into the packaging bag. The weighing platform can weigh in real time. Finally, when the powder in the packaging bag reaches the specified weight, the powder filling is stopped.

[0003] The invention disclosure document with patent application number 202110538112.2 discloses a semi-automatic packaging machine, which can manually clamp the bag on the discharge pipe of the packaging bag, and then fill and weigh it. After the filling is completed, the bag clamping mechanism is lowered as a whole, and the packaging bag is put down. Then other tools such as a forklift are used to move the filled packaging bag out.

[0004] However, the current semi-automatic packaging bag cannot achieve fully automatic packaging. The packaging bag needs to be manually taken out, opened, and packed. After filling, it needs to be moved out to another sealing machine for sealing. Therefore, the packaging efficiency of this semi-automatic packaging machine is too low. Summary of the Invention

Then the first bag moving clamping seat moves close to the side edge of the packaging bag and uses the first pneumatic clamp to clamp the side edge of the packaging bag. Similarly, the second bag moving clamping mechanism clamps the other side edge of the packaging bag. Then the shrinking and expanding clamping mechanism and the pressing block release the packaging bag and rise, so that the bag opening of the packaging bag is separated from the bag clamping support plate.

The sealing fixed bracket is provided with a pre-opening device for opening the bag mouth of the packaging bag above the first heating sealing component and the second heating sealing component.

Then the pre-opening device opens the bag mouth of the packaging bag, and the air extraction lifting power device drives the air extraction pipe to descend, and the air extraction pipe extends into the packaging bag. Then the second swing adjustment device controls the clamping parallel linkage mechanism to swing so that the first auxiliary clamping block and the auxiliary clamping device The second auxiliary clamping block swings into contact to seal and clamp the bag opening, and the vacuum pipe starts to pump air. After the vacuum is completed, the vacuum lifting power device drives the vacuum pipe to rise, and then the first swing adjustment device controls the heating parallel linkage mechanism to swing so that the first heating sealing component and the second heating sealing component clamp the bag opening and then seal it.

[0021] The lockhole that is formed on the second rotatable plate is formed on a pair of locking plate, and the locking plate is fixedly mounted on the locking plate, and the locking plate is connected with the locking plate at the locking cam.

In this way, it is only necessary to drive the first main link or the second main link to swing to make the first heating sealing assembly and the second heating sealing assembly swing at the same time, thereby improving efficiency. The same is true for the auxiliary clamping assembly. The third main connecting rod is rotatably mounted on the first rotating shaft. Therefore, when the first rotating shaft rotates, the third main connecting rod will not swing, and the fourth main connecting rod will not swing due to the rotation of the second rotating shaft. In use, the swing of the third main connecting rod drives the first clamping synchronous connecting block to swing, and the second clamping synchronous connecting block can be driven to swing through the clamping synchronous rod, and the fourth main connecting rod will swing accordingly to form a synchronous swing.

Two winding rollers are installed on the sealing frame. Polytetrafluoroethylene cloth is wound between the two winding rollers. A sealing block that contacts the packaging bag is provided on the sealing frame. A heating device is provided on the sealing block. The polytetrafluoroethylene cloth covers the sealing block. Since the temperature of the material strip will be too high when it directly contacts the packaging bag after heating by the heating device, it will cause the material strip to melt and affect the sealing. The polytetrafluoroethylene cloth can effectively insulate and ensure a certain temperature for sealing. The winding roller tightens the polytetrafluoroethylene cloth so that the polytetrafluoroethylene cloth is tightly attached to the sealing block to ensure the sealing quality.

[0023] As a preferred solution, the pre-opening device includes two opening brackets fixedly mounted on the sealing fixing bracket, each opening bracket is provided with a suction cup mounting strip mounted for transverse sliding movement, a number of pre-opening suction cups in contact with the packaging bag are mounted on the suction cup mounting strip in a longitudinal arrangement, each pre-opening suction cup mounting strip is also provided with a limit block for limiting the pre-opening suction cup, the limit block is provided with an upper strip groove corresponding to the lower strip groove, a third telescopic power device for driving the suction cup mounting strip to slide transversely is provided on the opening bracket, the air path between the pre-opening suction cup and the exhaust system is connected, the pre-opening device can pre-open the bag mouth of the clamped packaging bag, which can facilitate the insertion of the exhaust pipe.

[0075] The bag transfer device 4 in this embodiment can tighten and tidy up the bag opening of the packaging bag, so that there is no need to tidy up the bag opening when the bag enters the vacuum sealing machine 5.

[0076] like Figure 18 As shown, the bag transferring device 4 includes a bag transferring bracket 41 installed on the filling machine frame, a bag transferring longitudinal beam 42 is provided on the bag transferring bracket 41, a bag transferring slide 43 is installed on the bag transferring longitudinal beam 42 for longitudinal horizontal sliding, and a longitudinal bag transferring power device is installed on the bag transferring bracket 41 for driving the bag transferring slide 43 to slide longitudinally between the filling station D and the heat sealing station E, wherein the longitudinal bag transferring power device adopts the driving form of a motor and a chain or a synchronous belt to realize the sliding of the bag transferring slide 43.

[0077] The first bag moving clamping mechanism 44 and the second bag moving clamping mechanism 45 of the same structure are installed on the bag moving slide 43 for horizontal sliding.

[0078] The first bag moving and clamping mechanism 44 includes a first transverse slide 441, which is connected to the power end of the first telescopic power device 46. A first bag moving and clamping seat 4433 is movably installed on the first transverse slide 441. A first pneumatic clamp 442 for clamping the side of the packaging bag opening is installed on the first bag moving and clamping seat 4433. A first bag moving and feeding power device 443 that drives the first bag moving and clamping seat 4433 is installed on the first transverse slide 441. The first bag moving and feeding power device 443 drives the first bag moving and clamping seat 4433 to move close to the side of the packaging bag or away from the packaging bag.

The piston rod of the first bag-moving feeding cylinder 4432 is hingedly connected to the bracket of the first bag-moving clamping seat 4433. Therefore, when the first bag-moving feeding cylinder 4432 is extended or retracted, it drives the first bag-moving clamping seat 4433 to swing, thereby approaching the side edge of the packaging bag to complete clamping or away from the side edge of the packaging bag. After clamping the side edge of the packaging bag, it can also swing in opposite directions simultaneously, thereby quickly straightening the bag opening, thereby completing the bag opening straightening and improving the sealing effect during sealing.

[0079] After filling, the packaging bag descends and is supported by the front conveying device 3. At this time, the first horizontal slide 441 is driven by the first telescopic power device 46 to move horizontally so that the first bag moving clamping mechanism 44 and the second bag moving clamping mechanism 45 are respectively on both sides of the packaging bag.

Similarly, the second bag moving clamping mechanism 45 clamps the other side of the packaging bag, and then the shrinking and expanding clamping mechanism 755 and the pressing block 7542 release the packaging bag and rise, so that the bag mouth of the packaging bag is separated from the bag clamping support plate 752. The bag moving slide 43 is driven by the longitudinal bag moving power device from the filling station D to the heat sealing station. Since the side edge of the bag mouth of the packaging bag is always clamped in a tensioned state during the entire bag moving process, the bag mouth of the packaging bag will not collapse, and there is no need to tidy up the bag mouth during sealing later, thereby improving efficiency and ensuring sealing quality.

[0080] Figures 19 to 25 The figure shows a vacuum sealer 5, which is arranged at the heat sealing station E for vacuuming and heat-sealing the packaging bags.

The first swing adjustment device 511 includes a first swing adjustment cylinder 5111, which is hinged to the heating swing drive arm 5112, and the heating swing drive arm 5112 is fixed to the first rotating shaft 571. An auxiliary clamping device 59 is also installed below the sealing fixed end plate 56. The auxiliary clamping device 59 is located below the first heating sealing component 57 and the second heating sealing component 58. The auxiliary clamping device 59 includes two first auxiliary clamping blocks 591 and second auxiliary clamping blocks 592 that cooperate with each other to assist in clamping the bag opening of the sealed packaging bag. The first auxiliary clamping block 591 and the second auxiliary clamping block 592 are both provided with a lower strip groove 593 for avoiding the exhaust pipe 54;Both ends of the first auxiliary clamping block 591 and the second auxiliary clamping block 592 are swingably mounted on the sealing fixed end plate 56 by a clamping parallel linkage mechanism. A second swing adjustment device 596 is provided on the sealing fixed bracket 53 to swing the clamping parallel linkage mechanism. A pre-opening device 510 for opening the bag mouth of the packaging bag is provided above the first heating sealing component 57 and the second heating sealing component 58 on the sealing fixed bracket 53. The packaging bag filled with materials is longitudinally transported to the first heating sealing component 57 and the second heating sealing component 58 by the bag moving device 4. Then the pre-opening device 510 opens the bag mouth of the packaging bag, and the air suction lifting power device 55 drives the air suction pipe 54 to descend, and the air suction pipe 54 extends into the packaging bag. Then the second swing adjustment device 596 controls the swing of the clamping parallel linkage mechanism. The first auxiliary clamping block 591 and the second auxiliary clamping block 592 of the auxiliary clamping device 59 swing into contact, sealing and clamping the bag opening. The exhaust pipe 54 begins to exhaust. After the exhaust is completed, the exhaust lifting power device 55 drives the exhaust pipe 54 to rise. Then the first swing adjustment device 511 controls the heating parallel link mechanism to swing so that the first heating sealing component 57 and the second heating sealing component 58 clamp the bag opening and seal it. After the sealing is completed, the first auxiliary clamping block 591 and the second auxiliary clamping block 592 are opened by the clamping parallel link mechanism. The first heating sealing component 57 and the second heating sealing component 58 are also opened. The rear conveying device 6 sends the sealed packaging bag out. The vacuum sealing machine 5 can automatically and accurately exhaust and seal the packaging bag containing materials. The vacuuming time is short and the structure is compact, which improves efficiency. A cooling pipe 513 is provided downstream of the sealing fixing bracket 53 to blow air to the sealing area to quickly cool and shape it.

[0082] like Figure 23As shown, a first rotating shaft 571 and a second rotating shaft 581 are rotatably installed between the two sealing fixed end plates 56. The heating parallel linkage mechanism corresponding to the first heating sealing component 57 includes a first main linkage 572 and a first sub-link 573 parallel to each other. The heating parallel linkage mechanism corresponding to the second heating sealing component 58 includes a second main linkage 582 and a second sub-link 583 parallel to each other. The upper end of the first main linkage 572 is fixedly installed on the first rotating shaft 571, and the upper end of the first sub-link 573 is hinged to the sealing fixed end plate 56. The upper end of the second main linkage 582 is fixedly installed on the second rotating shaft 581, and the upper end of the second sub-link 583 is hinged to the sealing fixed end plate 56. The ends are hinged on the sealing fixed end plate 56, and the two ends of the first heating and sealing component 57 are respectively fixed to the lower ends of the corresponding first main connecting rod 572 and the first secondary connecting rod 573; the two ends of the second heating and sealing component 58 are respectively fixed to the lower ends of the corresponding second main connecting rod 582 and the second secondary connecting rod 583, and the first rotating shaft 571 and the second rotating shaft 581 are respectively fixed with the first heating synchronization connecting block 574 and the second heating synchronization connecting block 584, and the first heating synchronization connecting block 574 and the second heating synchronization connecting block 584 are hinged with a heating synchronization rod 575 that enables the first heating and sealing component 57 and the second heating and sealing component 58 to open and close synchronously; and the second auxiliary clamping block 592 The corresponding clamping parallel linkage mechanism includes a third main link 597 and a third sub-link 598 parallel to each other. The clamping parallel linkage mechanism corresponding to the second auxiliary clamping block 592 includes a fourth main link 594 and a fourth sub-link 595 parallel to each other. The upper end of the third main link 597 is rotatably mounted on the first rotating shaft 571, and the upper end of the third sub-link 598 is hinged to the sealing fixed end plate 56. The upper end of the fourth main link 594 is rotatably mounted on the second rotating shaft 581, and the upper end of the fourth sub-link 595 is hinged to the sealing fixed end plate 56. The two ends of the second auxiliary clamping block 592 are respectively fixed to the corresponding third main link 597 and the third sub-link. The lower end of the connecting rod 598, the two ends of the second auxiliary clamping block 592 are respectively fixed to the lower ends of the corresponding fourth main connecting rod 594 and the fourth sub-connecting rod 595, and the first rotating shaft 571 and the second rotating shaft 581 are respectively rotatably installed with the first clamping synchronous connecting block 5910 and the second clamping synchronous connecting block 599. The first clamping synchronous connecting block 5910 and the second clamping synchronous connecting block 599 are respectively installed on the third main connecting rod 597 and the fourth main connecting rod 594. A clamping synchronous rod 5911 is hinged between the first clamping synchronous connecting block 5910 and the second clamping synchronous connecting block 599 to enable the second auxiliary clamping block 592 and the second auxiliary clamping block 592 on the auxiliary clamping assembly to open and close synchronously.When it is necessary to drive the first main connecting rod 572 to swing, it is only necessary to rotate the first rotating shaft 571 to drive the first main connecting rod 572 to swing, and then the first heating synchronization connecting block 574 can drive the second heating synchronization connecting block 584 to rotate through the heating synchronization rod 575, so that the second main connecting rod 582 swings, and the corresponding first secondary connecting rod 573 and second secondary connecting rod 583 also swing, which can synchronize the first heating sealing assembly 57 and the second heating sealing assembly 58 to swing and clamp and seal, thus completing the clamping. In this way, only the first main connecting rod 572 or the second main connecting rod 582 needs to be driven to swing to make the first heating sealing assembly 57 and the second heating sealing assembly 58 swing. The component 57 and the second heating sealing component 58 swing at the same time to improve efficiency. The same applies to the auxiliary clamping component. The third main connecting rod 597 is rotatably installed on the first rotating shaft 571. Therefore, when the first rotating shaft 571 rotates, the third main connecting rod 597 will not swing, and the fourth main connecting rod 594 will not swing due to the rotation of the second rotating shaft 581. In use, the swing of the third main connecting rod 597 drives the first clamping synchronous connecting block 5910 to swing, and the clamping synchronous rod 5911 can drive the second clamping synchronous connecting block 599 to swing, and the fourth main connecting rod 594 will swing accordingly to form a synchronous swing.

[0083] The first heating and sealing assembly 57 and the second heating and sealing assembly 58 have the same structure.

A sealing block 579 that contacts the packaging bag is provided on the sealing frame 576. The sealing block 579 is provided with a heating device. The polytetrafluoroethylene cloth 578 covers the sealing block 579. Since the heating device directly contacts the packaging bag after heating, the temperature will be too high, causing the material strip to melt and affecting the sealing. The polytetrafluoroethylene cloth 578 can effectively insulate and ensure a certain temperature for sealing. In addition, the winding roller 577 tightens the polytetrafluoroethylene cloth 578 so that the polytetrafluoroethylene cloth 578 is tightly attached to the sealing block 579 to ensure the sealing quality.

[0084] The pre-opening device 510 includes two opening brackets fixedly mounted on the sealing fixing bracket 53, and a suction cup mounting strip 5101 is mounted on each opening bracket for horizontal sliding, and a number of pre-opening suction cups 5102 in contact with the packaging bag are mounted on the suction cup mounting strip 5101 in a longitudinal arrangement, and each pre-opening suction cup 5102 mounting strip is also provided with a limit block for limiting the pre-opening suction cup 5102, and the limit block is provided with an upper strip groove 5104 corresponding to the lower strip groove 593, and a third telescopic power device 5103 is provided on the opening bracket for driving the suction cup mounting strip 5101 to slide horizontally, and the air path between the pre-opening suction cup 5102 and the exhaust system is connected, and the pre-opening device 5100 can pre-open the bag mouth of the clamped packaging bag, so as to facilitate the insertion of the exhaust pipe 54.

[0085] The rear conveying device 6 is used to move the sealed packaging bags out.

[0086] Both the front conveying device 3 and the rear conveying device 6 can be conveyed by a belt conveying device or a roller conveying device.
