Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to the bag-lifting structure of a cement packaging bagging machine. Background Technology

[0002] Traditional cement production processes require multiple people to complete the cement bagging task, which is not only inefficient and costly but also causes serious pollution, posing a health risk to the operators. To overcome these problems, domestic manufacturers now use automatic cement bagging machines for cement bagging. Currently, these machines pick up empty cement bags by using a vacuum suction cup at the valve end, then using pressure rollers and a multi-wedge belt to transport the bag forward for the next step in the process.

[0003] A search revealed an existing patent (publication number: CN 208360608 U) disclosing a bag-lifting device and system for an automatic cement packaging bagging machine. The device is positioned above an empty cement bag and includes a vacuum suction cup positioned above the bag. The vacuum suction cup is mounted on a bag-lifting suction tube via a suction cup rod, wherein the length direction of the suction tube is perpendicular to the length direction of the suction cup rod. The bag-lifting suction tube is connected to a vacuum pump via an air pipe and is connected to the piston rod of a bag-lifting cylinder via a suction tube connecting plate. This invention prevents the tail end of the lifted empty cement bag from scraping against the lower cement bag during its forward movement, thus maintaining the neatness of the lower empty cement bag and improving the success rate of bag insertion.

[0004] However, while the above solution can achieve the purpose of extracting cement bags, there is no corresponding protective component at the bottom of the cement bag when the suction cup is adsorbed. If the cement bag is not firmly adsorbed, it may fall off during transportation.

[0005] In view of this, the present invention proposes a bag-lifting structure for a cement packaging bagging machine. Utility Model Content

[0006] This utility model proposes a bag-lifting structure for a cement packaging bagging machine, which solves the problem that although related technologies can achieve the purpose of extracting cement bags, when the suction cup adsorbs the cement bag, the bottom of the cement bag is not equipped with a corresponding protective component, and when the cement bag is not firmly adsorbed, it may fall off during transportation.

[0007] The technical solution of this utility model is as follows: A bag-lifting structure for a cement packaging bagging machine includes an electric cylinder. The output end of the electric cylinder is fixedly connected to a connecting plate. A micro vacuum pump is fixedly connected to the top of the connecting plate. A suction cup is fixedly connected to the bottom of the connecting plate. A first servo motor is fixedly connected to the surface of the connecting plate. A positive and negative lead screw that is rotatably connected to the connecting plate is fixedly connected to the output end of the first servo motor. Two sets of moving plates that are slidably connected to the connecting plate are threaded onto the surface of the positive and negative lead screws. An electric telescopic rod is fixedly connected to one side of each of the two sets of moving plates. A base plate is fixedly connected to the output end of each of the two sets of electric telescopic rods. Side plates are fixedly connected to both ends of each of the two sets of base plates.

[0008] Preferably, a base is provided below the electric cylinder, a vertical rod is fixedly connected to the top of the base, a transmission arm is rotatably connected to the top of the vertical rod, a second servo motor with its output end fixedly connected to the transmission arm is fixedly connected to the surface of the vertical rod, a slide plate fixedly connected to the electric cylinder is slidably connected to the surface of the transmission arm, and connecting rods slidably connected to the slide plate are fixedly connected to both ends of the transmission arm, with nuts threaded onto the surface of the connecting rods.

[0009] Preferably, the connecting plate is interconnected with the suction cup, and the suction cup is arranged vertically downwards.

[0010] Preferably, the two sets of motion plates are parallel to each other, and the center line of the two sets of motion plates coincides with that of the suction cup.

[0011] Preferably, the moving plate has a connecting groove inside for the base plate to slide, and the side plates are arranged in an "L" shape at both ends of the base plate.

[0012] Preferably, the base plate is positioned lower than the suction cup.

[0013] Preferably, the slide plate is in close contact with the transmission arm, and the transmission arm forms a rotating structure through a second servo motor.

[0014] Preferably, both sides of the slide plate are provided with transverse sliding grooves that are adapted to the size of the connecting rod, and the slide plate is fixed by nuts.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] In this invention, a base plate and side plates are provided. When the electric telescopic rod is opened, it pulls the base plate through the moving plate. At this time, the side plates also move. The moving plate moves to the bottom of the cement bag, and the side plates move to both sides of the cement bag. This prevents the cement bag from falling during transportation because the suction cups are not firmly attached to the cement bag. Under the action of the side plates and the base plate, when the cement bag falls, it will only fall on top of the base plate.

[0017] In this invention, a sliding plate is set up, and the second servo motor is turned on. The second servo motor controls the transmission arm to rotate and transfer the cement bag. When it is necessary to adjust the transfer position of the cement bag, simply slide the sliding plate along the surface of the connecting rod, adjust it to the designated position, and then tighten the nut on the sliding plate.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0025] A preferred embodiment of the cement packaging bagging machine lifting structure provided by this utility model is, for example... Figures 1 to 4As shown: The bag-lifting structure of a cement packaging bagging machine includes an electric cylinder 1. The output end of the electric cylinder 1 is fixedly connected to a connecting plate 2. A micro vacuum pump 3 is fixedly connected to the top of the connecting plate 2. A suction cup 4 is fixedly connected to the bottom of the connecting plate 2. A first servo motor 5 is fixedly connected to the surface of the connecting plate 2. The output end of the first servo motor 5 is fixedly connected to a positive and negative lead screw 17 that is rotatably connected to the connecting plate 2. Two sets of moving plates 6 that are slidably connected to the connecting plate 2 are threadedly connected to the surface of the positive and negative lead screw 17. An electric telescopic rod 7 is fixedly connected to one side of each set of moving plates 6. A base plate 8 is fixedly connected to the output end of each set of electric telescopic rods 7. Side plates 9 are fixedly connected to both ends of each set of base plates 8.

[0026] In this embodiment, the connecting plate 2 is interconnected with the suction cup 4. The suction cup 4 is set vertically downward. The electric cylinder 1 can be opened to control the connecting plate 2 to descend. When the suction cup 4 is attached to the cement bag, the micro vacuum pump 3 is turned on to create a vacuum inside the suction cup 4. Then the suction cup 4 will start to adsorb the cement bag.

[0027] In this embodiment, the two sets of motion plates 6 are parallel to each other and coincide with the center line of the suction cup 4. When the suction cup 4 is attached to the cement bag, the first servo motor 5 can be turned on to control the forward and reverse lead screws 17 to rotate. At this time, the two sets of motion plates 6 will move closer to each other to limit the two sides of the cement bag and prevent the cement bag from shifting when it is being suctioned.

[0028] In this embodiment, the moving plate 6 has a connecting groove inside for the base plate 8 to slide. The side plates 9 are arranged in an "L" shape at both ends of the base plate 8. When the electric telescopic rod 7 is opened, it pulls the base plate 8 through the moving plate 6. At this time, the side plates 9 will also move. The moving plate 6 will move to the bottom of the cement bag, and the side plates 9 will move to both sides of the cement bag. This prevents the suction cup 4 from not adhering firmly to the cement bag, which would cause the cement bag to fall during transportation. Under the action of the side plates 9 and the base plate 8, when the cement bag falls, it will only fall above the base plate 8.

[0029] In this embodiment, the bottom plate 8 is positioned lower than the suction cup 4, allowing the bottom plate 8 to move to the bottom of the cement bag. Example 2

[0030] Based on Embodiment 1, a preferred embodiment of the cement packaging bagging machine lifting structure provided by this utility model is, for example... Figures 1 to 4 As shown: A base 10 is provided below the electric cylinder 1. A vertical rod 11 is fixedly connected to the top of the base 10. A transmission arm 12 is rotatably connected to the top of the vertical rod 11. A second servo motor 13 with its output end fixedly connected to the transmission arm 12 is fixedly connected to the surface of the vertical rod 11. A slide plate 14 fixedly connected to the electric cylinder 1 is slidably connected to the surface of the transmission arm 12. Connecting rods 15 slidably connected to the slide plate 14 are fixedly connected to both ends of the transmission arm 12. Nuts 16 are threadedly connected to the surface of the connecting rods 15.

[0031] In this embodiment, the slide plate 14 is closely fitted with the transmission arm 12. The transmission arm 12 forms a rotating structure through the second servo motor 13. When the second servo motor 13 is turned on, the second servo motor 13 will control the transmission arm 12 to rotate and transfer the cement bag.

[0032] In this embodiment, both sides of the slide plate 14 are provided with transverse sliding grooves that are adapted to the size of the connecting rod 15. The slide plate 14 is fixed by the nut 16. When it is necessary to adjust the transfer position of the cement bag, simply slide the slide plate 14 along the surface of the connecting rod 15, adjust it to the specified position, and then tighten the nut 16 on the slide plate 14.

[0033] The working principle and usage process of this utility model are as follows: First, when it is necessary to lift the cement bag, the electric cylinder 1 can be turned on to control the connecting plate 2 to descend. When the suction cup 4 is in contact with the cement bag, the micro vacuum pump 3 is turned on to create a vacuum inside the suction cup 4. Then, the suction cup 4 will begin to adsorb the cement bag. By setting the motion plate 6, when the suction cup 4 is in contact with the cement bag, the first servo motor 5 can be turned on to control the forward and reverse lead screws 17 to rotate. At this time, the two sets of motion plates 6 will move closer to each other to limit the two sides of the cement bag and prevent the cement bag from shifting when it is being adsorbed. Then, the electric cylinder 1 controls the cement bag to rise, and then the electric telescopic rod 7 is turned on to pull the bottom. Plate 8 passes through moving plate 6, and at this time, side plate 9 will also move. Moving plate 6 will move to the bottom of cement bag, and side plate 9 will move to both sides of cement bag to prevent the cement bag from falling during transfer due to the suction cup 4 not being firmly attached to it. Under the action of side plate 9 and bottom plate 8, when the cement bag falls, it will only fall above bottom plate 8. After suction cup 4 has finished attaching, the second servo motor 13 is turned on. The second servo motor 13 will control the transmission arm 12 to rotate and transfer the cement bag. When it is necessary to adjust the transfer position of the cement bag, simply slide the slide plate 14 along the surface of connecting rod 15. After adjusting to the specified position, tighten nut 16 on slide plate 14.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
