[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] Example: Automatic liquid filling vacuum sealing machine, such as Figures 1-13 As shown, it includes a sealing machine body 1, and a feeding mechanism 2 fixedly mounted on one side surface thereof, a clamping claw conveying mechanism 4 is provided at the upper end of the outlet of the feeding mechanism 2, a liquid injection mechanism 3 is provided on one side of the clamping claw conveying mechanism 4, and a pushing mechanism 9 is provided on the lower side near one end of the clamping claw conveying mechanism 4;

[0048] The pushing mechanism 9 includes a push rod slot 901 and a push rod assembly 902 slidably connected to the upper surface thereof. The push rod assembly 902 is plugged into a positioning slot 903 . A suction cup transport mechanism 6 is provided near one end of the positioning slot 903 .

[0049] The suction cup transport mechanism 6 includes a movable groove 603, and a first lifting platform 601 and a second lifting platform 602 that are symmetrically connected to the movable groove 603. Suction heads 604 are fixedly installed on the lower surfaces of the first lifting platform 601 and the second lifting platform 602. A vacuum pumping mechanism 5 is provided on one side of the suction cup transport mechanism 6.

[0050] The vacuum mechanism 5 includes two symmetrical vacuum platforms 501. A vacuum pad 502 is fixedly mounted on one side of each vacuum platform 501. A cylinder body 504 is fixedly mounted on the upper end of the vacuum platform 501 via a connecting plate. An auxiliary guide rod 505 is fixedly mounted on the cylinder body 504 via an L-shaped connecting plate. An auxiliary plate 503 is fixedly mounted near one end of the auxiliary guide rod 505.

[0051] A bag expanding mechanism 7 is provided between the suction cup transport mechanism 6 and the vacuum pumping mechanism 5 .

[0052] The automatic liquid injection vacuum sealing machine adopts PLC control program, infrared detection equipment and pneumatic drive. The above are existing technologies known in this field and will not be described in detail here and are not shown in the figure. The vacuum pad 502 adopts a material with high plasticity and wear resistance. The pre-pressing device and heating wire are existing technologies and will not be described in detail here and are not shown in the figure.

[0053] Among them, when feeding, first through the feeding mechanism 2 conveying, the feeding mechanism 2 can convey two hours' worth of products at a time, and can transport the crucible product to the upper end of the feeding mechanism 2. At the same time, through the program and the infrared detection device control, the crucible product can be kept at the upper end of the outlet of the feeding mechanism 2. At this time, the clamping claw conveying mechanism 4 can clamp and move the crucible product in turn. Through the clamping of the clamping claw conveying mechanism 4, the crucible product can be prevented from being on the liquid injection mechanism 3. The liquid injection mechanism 3 performs an initial weight test on the crucible product. After the test is completed, the liquid injection mechanism 3 will inject liquid into the crucible product in turn. When the injection is completed, it will be weighed again to detect whether the injection amount meets the standard. If it does not meet the standard, it will be taken out manually. If the injection meets the standard, At this time, the gripper transport mechanism 4 can transport the qualified crucible product to the pushing mechanism 9. At the same time, the first lifting platform 601 of the suction cup transport mechanism 6 moves to the aluminum foil bag placement area. By moving the first lifting platform 601 downward, the suction head 604 on it can contact the aluminum foil bag. At this time, the suction head 604 can stably suck the aluminum foil bag. At the same time, the first lifting platform 601 moves upward to lift the aluminum foil bag, and at the same time, it shakes up and down briefly multiple times to prevent the aluminum foil bag below from being driven away. At the same time, it can ensure that only one aluminum foil bag can be transported at a time. At this time, the first lifting platform 601 transports the aluminum foil bag to the bagging waiting position. At the same time, the suction head 604 opens the bag mouth of the aluminum foil bag. At this time, the push rod assembly 902 can push the crucible product into the aluminum foil bag. Compared with multiple mechanical connecting rods, the push rod groove 901 thereon can ensure the stability of the push through a simple mechanical structure, avoid the damage of the crucible product caused by the misalignment of the push, and at the same time, the positioning groove 903 is set to ensure that the crucible product can smoothly enter the aluminum foil bag, thereby ensuring the accurate effect of automatic bagging. At the same time, under the joint use of the suction cup conveying mechanism 6 and the push rod mechanism 9, the effect of automatic bagging is achieved. At this time, the first lifting platform 601 moves to the aluminum foil bag placement area to carry out the next aluminum foil bag picking process. At the same time, the second lifting platform 602 moves to the bagging waiting position to pick up the aluminum foil bag containing the crucible product. At the same time, the bag expanding mechanism 7 can open the bag mouth of the aluminum foil bag again by descending, thereby preparing for vacuuming. At this time, the second lifting platform 601 moves to the bagging waiting position to pick up the aluminum foil bag containing the crucible product. The platform 602 places the aluminum foil bag between the vacuum platforms 501 of the vacuum mechanism 5. At the same time, the cylinder body 504 drives the auxiliary guide rod 505 to move. At this time, the auxiliary plate 503 can be inserted into the aluminum foil bag. At this time, the vacuum platform 501 is combined to perform vacuuming. At the same time, the pre-pressing device in the vacuum mechanism 5 will pre-press and fix the aluminum foil bag to prevent it from being severely deformed. The vacuum pads 502 fit together to form a sealed environment, thereby ensuring the vacuuming effect. At this time, since the auxiliary plate 503 is inside the aluminum foil bag, a certain amount of space is occupied inside the aluminum foil bag. At this time, the inside and outside of the aluminum foil bag can be vacuumed at the same time. At the same time, when the internal vacuuming is in progress, the aluminum foil bag begins to fit from the inside to the bag opening. When the vacuum value reaches more than 90%,The auxiliary guide rod 505 draws the auxiliary plate 503 out of the inside of the aluminum foil bag. At the same time, as the auxiliary plate 503 moves, the inside of the aluminum foil bag gradually fits outward as it moves. At this time, the vacuuming continues to work. The heating wire at the bottom of the bag mouth heats and seals it. When the bag mouth is sealed, the vacuum pump stops working and the vacuuming table 501 rises and opens. At this time, the internal pre-pressing device hooks the aluminum foil bag out and moves it to the discharge port, thereby completing the work. Through the movement and occupation of the auxiliary plate 503, it can ensure that a high vacuum is maintained inside the aluminum foil bag and that the aluminum foil bag is not excessively deformed, thereby achieving a good vacuuming effect. At the same time, the auxiliary plate 503 The presence of the auxiliary plate 503 allows for simultaneous vacuuming of both the exterior and interior, thereby accelerating the vacuuming process and achieving a rapid vacuuming effect. The provision of the first lifting platform 601 allows for the grabbing and simultaneous opening of the aluminum foil bag, ensuring that the pushing mechanism 9 accurately pushes the crucible product into the aluminum foil bag, eliminating the complex manual bagging steps and achieving an automatic bagging effect. The provision of the second lifting platform 602 allows the aluminum foil bag containing the crucible product to be grabbed and placed on the vacuuming mechanism 5, completing the automatic vacuuming step and achieving an automatic vacuuming effect.

[0054] like Figures 1-13 As shown, one end of the auxiliary guide rod 505 extends to the inside of one of the vacuum platforms 501, and the peripheral side of the auxiliary guide rod 505 is slidably connected to the inner wall of the vacuum platform 501, the auxiliary plate 503 moves between the two vacuum mechanisms 5, and a rectangular hole of varying lengths is opened through the middle of the auxiliary plate 503.

[0055] Four symmetrical suction heads 604 are installed at the corners of the lower surface of the first lifting platform 601 , and two symmetrical suction heads 604 are installed at the corners of the lower surface of the second lifting platform 602 .

[0056] The sliding connection between the auxiliary guide rod 505 and the vacuuming table 501 can ensure that the auxiliary plate 503 remains horizontal and stable when it is pulled out, thereby effectively ensuring the vacuuming effect. At the same time, the rectangular holes on the auxiliary plate 503 can make the gas in the aluminum foil bag be discharged more evenly during the vacuuming process, avoiding excessive deformation or even damage of the aluminum foil bag caused by excessive local pressure difference. At the same time, the rectangular holes can allow the gas to flow more evenly in the bag, making the vacuum degree of each part of the aluminum foil bag more uniform after vacuuming, speeding up the vacuuming speed and helping to maintain the stability of the product in a vacuum environment, preventing local vacuum Insufficient degree affects the preservation or quality of the product, thereby achieving the effect of better vacuuming and faster vacuuming. Four suction heads 604 are set on the first lifting platform 601, which can stably take the aluminum foil bag and support the first lifting platform 601 to move up and down briefly multiple times to ensure that the taken aluminum foil bag will not fall. At the same time, two suction heads 604 are set on the second lifting platform 602, which can keep the aluminum foil bag opening normally open when taking the aluminum foil bag containing the crucible product, thereby ensuring the entry of the auxiliary plate 503, thereby achieving the stability of automatic bagging and the effect of faster vacuuming and better vacuuming.

[0057] like Figures 1-13 As shown, the feeding mechanism 2 includes a conveyor belt 203 and a limiting frame 201 arranged on the upper surface of the conveyor belt 203, and a support plate 202 is inserted at the lower end of the limiting frame 201.

[0058] The clamping jaw conveying mechanism 4 includes a traveling groove 401 and a first conveying jaw 402 and a second conveying jaw 403 slidably connected to a side surface of the traveling groove 401 .

[0059] The first transport clamp 402 can be moved to the upper end of the outlet of the feeding mechanism 2 and above the liquid injection mechanism 3 , and the second transport clamp 403 can be moved to the upper end of the pushing mechanism 9 and above the liquid injection mechanism 3 .

[0060] The liquid injection mechanism 3 includes a sliding groove 301 and a liquid injector 302 slidably connected to a surface of one side of the sliding groove 301 . There are multiple liquid injectors 302 arranged in a line. A meter 303 is provided on the lower side of the liquid injector 302 .

[0061] The crucible products placed in the limiting frame 201 are arranged up and down in sequence. At this time, by placing the limiting frame 201 on the brackets on both sides of the conveyor belt 203, the crucible products can be in a vertical state with the conveyor belt 203. At this time, the support plate 202 on the lower side of the limiting frame 201 is pulled out, and the crucible products can fall onto the conveyor belt 203, and are transported forward by the conveyor belt 203 to the screw mechanism. The screw mechanism can transport the crucible products to the upper end of the feeding mechanism 2. By setting the limiting frame 201, it can be loaded with a large number of crucible products at a time, thereby eliminating the step of manual placement and reducing the chance of tipping, thereby achieving the effect of automatic loading stability. At the same time, by setting the moving range of the first carrying clamp 402, it can be ensured that it can feed the feeding mechanism 2 The crucible product at the upper end is clamped and placed on the meter 303, thereby ensuring the accurate effect of automatic clamping and placement. At the same time, the moving range of the second transport clamp 403 can accurately ensure that the crucible product on the meter 303 is grabbed and moved to the pushing mechanism 9. Through the accuracy of placement, it can ensure that the crucible product is accurately pushed into the aluminum foil bag by the pushing mechanism 9, thereby achieving the effect of accurate bagging. Compared with the movement of the manipulator, the sliding groove 301 can ensure that the injector 302 remains sufficiently stable during injection, and at the same time can ensure the qualified rate of the product, thereby achieving the effect of stable and accurate injection and a high product qualified rate. At the same time, the injectors 302 with a certain arrangement order can perform the injection process on multiple crucible products at a time, thereby increasing the injection efficiency.

[0062] like Figures 1-13 As shown, the bag expanding mechanism 7 is arranged between the suction cup transport mechanism 6 and the vacuum pumping mechanism 5 , and the bag expanding mechanism 7 is fixedly connected to the upper surface of the sealing machine body 1 .

[0063] The bag expanding mechanism 7 includes a support frame 701 , a fixing platform 702 , a bag expander 703 , and a sliding rod 704 .

[0064] A fixed platform 702 is fixedly installed on one side of the support frame 701. A sliding rod 704 is slidably connected to one side of the fixed platform 702. A bag expander 703 is fixedly installed on one side of the sliding rod 704. The sliding rod 704 and the bag expander 703 are L-shaped.

[0065] When the second lifting platform 602 is taking and moving the aluminum foil bag, the pneumatic device, supported by the fixed platform 702 and the support frame 701, can drive the sliding rod 704 to drive the bag expander 703 to move downward, thereby opening and expanding the bag opening of the aluminum foil bag, thereby ensuring that the auxiliary plate 503 stably enters the interior of the aluminum foil bag, thereby ensuring a good vacuuming effect. At the same time, the sliding rod 704 and the bag expander 703 are L-shaped, which can ensure that the sliding rod 704 can drive the bag expander 703 to move accurately, avoiding misalignment during the movement process, resulting in poor opening of the aluminum foil bag or the aluminum foil bag being torn, thereby achieving a good opening effect of the aluminum foil bag and protecting the aluminum foil bag.

[0066] Working principle: When automatic liquid injection and vacuum sealing are performed, the crucible product is first placed on the conveyor belt 203 through the limiting frame 201. The crucible product can be transported to the upper end of the feeding mechanism 2 through the transmission of the conveyor belt 203 and the screw rod. At this time, the first handling clamp 402 places the crucible product on the metering device 303. After the metering device 303 weighs, the liquid injector 302 injects liquid into it. At the same time, the first lifting platform 601 takes the aluminum foil bag and opens the bag. The second handling clamp 402 is used to carry out the automatic liquid injection and vacuum sealing. The claw 403 clamps the crucible product and places it on the pushing mechanism 9. The push rod assembly 902 pushes the crucible product into the aluminum foil bag. The second lifting platform 602 takes the aluminum foil bag. At the same time, the bag expander 703 opens the bag mouth of the aluminum foil bag again. The second lifting platform 602 places the aluminum foil bag in the vacuum platform 501. The auxiliary plate 503 enters the aluminum foil bag. The vacuum platform 501 is combined and vacuumed. The auxiliary plate 503 is pulled out to seal the aluminum foil bag. The automatic liquid injection and vacuum sealing work is completed.
