Description

Technical Field

[0001] The utility model relates to the technical field of automatic mechanical equipment, in particular to a full-automatic keel bag opening machine. Background Technique

[0002] A keel bag is a plastic bag that can be automatically sealed by pressing, which is made by blowing film and cutting bags with polyethylene and high-voltage linear polyethylene. Common keel bags include zip keel bags and concave-convex rib type keel bags, and the concave-convex rib type keel bags account for the vast majority.

[0003] During the production process and after processing of the concave-convex rib type keel bags, the concave-convex ribs are in a closed state. Therefore, when putting items into the keel bag, it is necessary to separate the concave-convex ribs and open the keel bag. At present, most of the opening of keel bags is done manually, and the operation process is complicated. Such an operation method requires a large amount of manpower and has a high labor intensity. Secondly, the existing keel bag opening equipment has a low degree of automation and a slow working speed, which greatly reduces the efficiency of opening keel bags. Content of the Utility Model

[0004] The purpose of the utility model is to provide a full-automatic keel bag opening machine with a high degree of automation.

[0005] To achieve the above purpose, the utility model provides the following technical solutions.

[0006] A full-automatic keel bag opening machine has a workbench. On the upper surface of the workbench, an installation frame is fixed by four columns. There is a bag-taking station that runs through up and down on the installation frame. A micro conveyor belt is arranged on the installation frame in front of the bag-taking station. The micro conveyor belt is used to convey the keel bag to the bag-taking station. There is an opening station that runs through up and down on the installation frame on one side of the bag-taking station. A material receiving guide groove is arranged below the installation frame in front of the opening station. The material receiving guide groove is used to discharge the opened keel bag; A transfer suction cup is arranged below the installation frame through a double-axis moving module. The double-axis moving module is used to drive the transfer suction cup to move between the bag-taking station and the opening station, and the double-axis moving module can also drive the transfer suction cup to move up and down; A pressing mechanism is arranged on the installation frame corresponding to the position of the bag-taking station. The pressing mechanism is used to press the keel bag on the transfer suction cup. An adsorption seat is installed on the installation frame through a first conveying mechanism. A positioning suction cup is installed at the bottom of the adsorption seat. The first conveying mechanism is used to drive the adsorption seat to move between the opening station and the material receiving guide groove; A fixed frame is also arranged below the installation frame through a translation mechanism. The translation mechanism is used to drive the fixed frame to perform translation adjustment along the moving direction of the transfer suction cup. A friction block and an opening suction cup are installed on the side of the fixed frame through a lifting mechanism. The lifting mechanism is used to drive the friction block and the opening suction cup to perform lifting and moving respectively.

[0007] It can be seen that the keel bag can be transported to the bag-taking station by the operation of the micro belt line. The transfer suction cup can be driven to move by the double-axis moving module, and the keel bag at the bag-taking station can be transferred to the bag-opening station. The positioning suction cup can be driven to move by the first conveying mechanism, and the opened keel bag can be transferred to the material receiving guiding groove, forming a continuous transfer production line. When the keel bag is at the bag-opening station, through the cooperation of the translation mechanism, the lifting mechanism, the positioning suction cup, the friction block and the bag-opening suction cup, the automatic opening operation of the keel bag can be realized. When opening the keel bag, the upper bag body is sucked tightly by the positioning suction cup, and the bag body corresponding to the middle part of the concave and convex bone strips is sucked tightly by the bag-opening suction cup to prevent the keel bag from falling. The lifting mechanism works to push the friction block upward to contact the concave and convex bone strips of the bag body. The translation mechanism drives the friction block to reciprocate, so that the friction block and the concave and convex bone strips rub against each other, realizing the rubbing action. The concave and convex bone strips can be rubbed out of position, and cooperating with the bag-opening suction cup to pull open the concave and convex bone strips, the opening of the keel bag is realized. The degree of automation is high, the working speed is fast and the stability is high, effectively improving the efficiency of opening the keel bag. The working speed is fast and the stability is high, effectively improving the efficiency of opening the keel bag.

[0012] Preferably, each cantilever has three transfer suction cups, and each installation plate has three pressing convex heads; the point positions of the pressing convex heads are distributed in one-to-one correspondence with the point positions of the transfer suction cups.

[0013] When pressing the keel bag against the transfer suction cup, since the point positions of the downward pressing convex heads correspond one-to-one with those of the transfer suction cup, the downward pressing convex heads can accurately press the bag body against the transfer suction cup, facilitating the transfer suction cup to hold the bag body. Secondly, the connecting lines of the distribution points of the downward pressing convex heads and the transfer suction cup are all triangular shapes, so that the bag body can be held at three points, with high firmness and ensuring uniform force distribution on the bag body, making it not easy to damage the bag body.

By the fourth cylinder extending to work, under the connection action of the first mounting block, the friction block can be pushed upward to abut against the concave-convex bone strip, facilitating the rubbing action. By the fifth cylinder extending to work, under the connection action of the second mounting block, the bag-opening suction cup is pushed upward to contact the bag body, and the position corresponding to the middle part of the lower-layer bag body and the concave-convex bone strip can be sucked tightly.

Detailed implementation manners

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0037] Please refer to Figures 1 - 10 , the present utility model provides a full-automatic keel bag opening machine, which has a workbench 1. An installation platform frame 2 is fixed on the upper surface of the workbench 1 through four columns 11. A bag-taking station 21 that penetrates up and down is provided on the installation platform frame 2. A micro belt line 24 is provided on the installation platform frame 2 at the front side of the bag-taking station 21. The micro belt line 24 is used to convey the keel bag to the bag-taking station 21. An opening station 22 that penetrates up and down is provided on the installation platform frame 2 at one side of the bag-taking station 21. A material receiving guiding groove 23 is provided below the installation platform frame 2 at the front side of the opening station 22. The material receiving guiding groove 23 is used to discharge the opened keel bag; A transfer suction cup 6 is provided below the installation platform frame 2 through a double-axis moving module 7. The double-axis moving module 7 is used to drive the transfer suction cup 6 to move between the bag-taking station 21 and the opening station 22. The double-axis moving module 7 can also drive the transfer suction cup 6 to move up and down. When using this equipment to open the keel bag, first, the double-axis moving module 7 works to drive the transfer suction cup 6 to move below the bag-taking station 21, and then the double-axis moving module 7 works to drive the transfer suction cup 6 to move upward to receive the keel bag. Then, the keel bag is loaded onto the micro belt line 24. The micro belt line 24 can convey the keel bag to the bag-taking station 21 and be located above the transfer suction cup 6;

[0038] A pressing mechanism 3 is provided on the installation platform frame 2 corresponding to the position of the bag-taking station 21. The pressing mechanism 3 is used to press the keel bag onto the transfer suction cup 6. An adsorption seat 5 is installed on the installation platform frame 2 through a first conveying mechanism 4. A positioning suction cup 51 is installed at the bottom of the adsorption seat 5. The first conveying mechanism 4 is used to drive the adsorption seat 5 to move between the opening station 22 and the material receiving guiding groove 23. The pressing mechanism 3 works to press the keel bag onto the transfer suction cup 6, and then the transfer suction cup 6 is used to suck the keel bag tightly. After the keel bag is sucked tightly on the transfer suction cup 6, the pressing mechanism 3 resets. Then, the double-axis moving module 7 works to drive the transfer suction cup 6 and the keel bag to move horizontally to the opening station 22. The double-axis moving module 7 works to drive the transfer suction cup 6 to move upward, pushing the keel bag upward to contact the positioning suction cup 51 below the adsorption seat 5. The positioning suction cup 51 works to suck the keel bag tightly, and at the same time, the transfer suction cup 6 deflates to release the keel bag. Subsequently, the double-axis moving module 7 works to drive the transfer suction cup 6 to move back to the position below the bag-taking station 21;

[0039] Below the installation bench 2, a fixing frame 901 is also arranged through a translation mechanism 8. The translation mechanism 8 is used to drive the fixing frame 901 to perform translational adjustment along the moving direction of the transfer suction cup 6. A friction block 02 and a bag-opening suction cup 04 are installed on the side of the fixing frame 901 through a lifting mechanism 9. The lifting mechanism 9 is used to drive the friction block 02 and the bag-opening suction cup 04 to perform lifting and moving respectively. By operating the translation mechanism 8, the fixing frame 901 is driven to move below the keel bag, and it is ensured that the friction block 02 is aligned with the concave and convex rib of the keel bag. By operating the lifting mechanism 9, the friction block 02 and the bag-opening suction cup 04 are pushed upward. The bag-opening suction cup 04 moves upward to suck and tighten the position corresponding to the middle part between the bag body and the concave and convex rib, which cooperates with the positioning suction cup 51 to suck and tighten the upper part of the bag body, can prevent the bag body from falling, and ensure the stability during bag opening. The friction block 02 moves upward to contact the concave and convex rib of the bag body. Subsequently, through the reciprocating operation of the translation mechanism 8, the friction block 02 and the bag-opening suction cup 04 are driven to move to one side. When the friction block 02 moves, it rubs against the concave and convex rib, realizing the rubbing action, and the concave and convex ribs can be staggered. At the same time, the bag-opening suction cup 04 moves, and the bag mouth can be pulled open, thus realizing the opening operation;

[0040] After the keel bag is opened, the bag-opening suction cup 04 cancels the suction on the bag body. By operating the first conveying mechanism 4, the adsorption seat 5 and the positioning suction cup 51 are driven to move toward the side of the receiving guiding groove 23, and then the opened keel bag can be driven to move to the receiving guiding groove 23. Subsequently, the positioning suction cup 51 is depressurized to cancel the suction on the keel bag, and the keel bag drops downward into the receiving guiding groove 23 and slides out from the receiving guiding groove 23 to realize the discharging. Through the above entire process, the opening operation of the keel bag can be realized.

By the telescopic operation of the second cylinder 75, under the connection action of the installation arm 76 and the cantilever 77, the transfer suction cup 6 can be driven to move up and down, so as to facilitate the transfer of the keel bag from the bag-taking station 21 to the bag-opening station 22;

When the first cylinder 32 pushes the mounting plate 33 and the pressing-down convex heads 34 downward, the keel bag at the bag-taking station 21 can be pressed tightly on the transfer suction cup 6, ensuring that the keel bag can be successfully sucked tightly by the transfer suction cup 6;

[0043] Each cantilever 77 has three transfer suction cups 6, and each mounting plate 33 has three pressing-down convex heads 34; the point positions of the pressing-down convex heads 34 are distributed in one-to-one correspondence with the point positions of the transfer suction cups 6, so that the pressing-down convex heads 34 can accurately press the bag body on the transfer suction cup 6, facilitating the transfer suction cup 6 to hold the bag body. Secondly, the connecting lines of the distribution point positions of the pressing-down convex heads 34 and the transfer suction cups 6 are all triangular shapes, and thus the bag body can be held at three points, with high firmness and ensuring uniform force distribution on the bag body, and the bag body is not easily damaged.
