[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example:
[0028] Refer to the attached Figure 1-4 As shown, a fully automatic self-sealing bag opening system for tobacco includes:
[0029] Electrical control box 2, equipped with a PLC controller that communicates with the host computer, enables high-speed and precise control of self-sealing bag opening and sealing, and tobacco shred dispensing. Electrical control box 2 is installed on the weighing system platform. The PLC controller communicates with the first electric cylinder assembly, the fixed cylinder, and the moving cylinder. Specifically, the host computer includes an operation interface, a data display interface, and a data query interface.
[0030] The first electric cylinder assembly 1 is connected to the electric control box 2 through a cable, and includes: an X-axis guiding square steel, a Y-axis guiding square steel, an X-axis electric cylinder 1-2, a Y-axis electric cylinder 1-1, a rotary cylinder 8, an unsealing suction cup A7, and a suction cup mounting frame. Among them, the X-axis electric cylinder 1-2 is arranged inside the X-axis guiding square steel, and the Y-axis electric cylinder 1-1 is arranged inside the Y-axis guiding square steel to seal and limit the X-axis electric cylinder 1-2 and the Y-axis electric cylinder 1-1 respectively through the X-axis guiding square steel and the Y-axis guiding square steel; and the Y-axis guiding square steel is connected to the X-axis electric cylinder 1-2 to drive the Y-axis guiding square steel and the Y-axis electric cylinder 1-1 inside it to move in the left and right directions through the X-axis electric cylinder 1-2; the screw end of the Y-axis electric cylinder 1-1 is connected to the rotary cylinder, and the screw end of the rotary cylinder is connected with a suction cup mounting frame. A number of unsealing suction cups A7 are arranged in rows on the suction cup mounting frame. The opening end side of the self-sealing bag is adsorbed by the negative pressure air flow generated by the number of unsealing suction cups A7, and it is driven by the Y-axis electric cylinder 1-1 to move upward. When it moves to a suitable position, it is rotated by the rotary cylinder 8 to face the weighing system platform, and is driven by the X-axis electric cylinder 1-2 to move to one side of the weighing system platform. At the same time, the Y-axis electric cylinder 1-1 drives it to move downward to the unsealing position.
[0031] Preferably, the self-sealing bags are stacked layer by layer inside the self-sealing bag baffle, and the position of the self-sealing bags is limited by the self-sealing bag baffle to ensure the position where the number of unsealing suction cups A7 grab the self-sealing bags.
[0032] In addition, optionally, the number of unsealing suction cups A7 are arranged in three rows. Of course, they can also be arranged in other rows. And at least two rows of the unsealing suction cups A close to the opening end of the self-sealing bag have negative pressure air flow transmission, and the row of unsealing suction cups A far from the opening of the self-sealing bag has no negative pressure air flow transmission. While saving the air source, the rotation position of the self-sealing bag during rotation can be limited to avoid damage during the rotation process. And the suction cup mounting frame is in a "day" - shaped structure, which is convenient for observing the state of the self-sealing bag.
[0033] The first electric cylinder assembly can quickly and accurately adsorb and grab the self-sealing bag through precise positioning. Through the unsealing suction cup A equipped with the rotary cylinder 8, it can stably and quickly adsorb the self-sealing bag and quickly and accurately move to the unsealing suction cup B6 through the X-axis electric cylinder 1-2 and the Y-axis electric cylinder 1-1.
[0034] The unsealing bag fixing bracket 9 is fixedly arranged on the weighing system platform through screws, and a number of unsealing suction cups B6 are arranged on it opposite to the uppermost unsealing suction cup A7 to respectively suck the opening end side of the self-sealing bag through the interaction between the unsealing suction cup B6 and the unsealing suction cup A7, and the X-axis electric cylinder is used to drive the unsealing suction cup A away from the unsealing suction cup B to smoothly and stably open the self-sealing bag, so as to grab the cut tobacco inside and load it into the sample box.
[0035] In one specific embodiment, a Y-axis electric cylinder 5 is fixedly installed on the top of the self-sealing bag fixing bracket 9. The Y-axis electric cylinder 5 is also connected to the electrical control box 2 via a cable. The Y-axis electric cylinder 5 is equipped with a fixed separating clamp 3 and a movable sealing clamp 4. When the self-sealing bag is opened, the movable sealing clamp 4 moves downward to clamp the rear end of the self-sealing bag on the opening side. Then, the fixed separating clamp 3 moves downward to clamp the self-sealing bag on the opening side close to the rear end. The self-sealing bag is clamped by the fixed separating clamp 3 and the movable sealing clamp 4. At this time, the first electric cylinder assembly 1 is released and moves away from the self-sealing bag. Finally, the movable sealing clamp 4 moves along the Y-axis electric cylinder 5 to the front end of the self-sealing bag on the opening side to seal the self-sealing bag and retain a sample.
[0036] Specifically, the fixed separating clamp 3 has a fixed cylinder 3-1 and a downward fixed clamp 3-2 connected to the fixed cylinder 3-1; the movable sealing clamp 4 has a movable cylinder 4-1 and a downward movable clamp 4-2 connected to the movable cylinder 4-1, so that the fixed clamp 3-2 and the movable clamp 4-2 can move up and down to clamp the self-sealing bag through the connection of the fixed cylinder 3-1 and the movable cylinder 4-1 to the electrical control box 2. The movable sealing clamp 4 is connected to the lead screw end of the Y-axis electric cylinder 5, so that the movable sealing clamp 4 can move back and forth through the Y-axis electric cylinder 5.
[0037] The system is also equipped with a high-precision weighing sensor to weigh the tobacco shreds. After weighing, the fixed cylinder 3-1 extends and reaches the position of the self-sealing bag opening, and the fixed clamp 3-2 closes to clamp the self-sealing bag opening. The fixed clamp 3-2 installed on the side near the fixed separating clamp 3 extends and reaches the position of the self-sealing bag opening, and the moving clamp 4-2 closes to clamp the self-sealing bag opening. The Y-axis electric cylinder 5 drives the moving sealing clamp 4 installed on it to move forward smoothly, so that the self-sealing bag opening is sealed. After sealing, the Y-axis electric cylinder 5 drives the moving sealing clamp 4 installed on it to reset.
[0038] In an optional embodiment, the fully automated tobacco self-sealing bag opening system further includes: a high-speed six-axis robot that requires no electrical control cabinet, featuring an integrated robotic arm design and operating within a touch-screen PC. The six-axis robot achieves the required running trajectory with high speed, precision, and stability. The PLC controller communicates at high speed with the control system of the six-axis robot, reading the robot's operating status and trajectory, and simultaneously enabling communication for the six-axis robot's control. When the tobacco sorting equipment starts operating, the PLC controller sends a start command to control the robotic arm to run and execute corresponding actions, thus achieving connection between the robot and the host system.
[0039] This utility model discloses a fully automatic tobacco self-sealing bag opening and sealing system with a simple structure. It uses suction cups with negative pressure to suck up both sides of the self-sealing bag. By moving the relative positions of the two suction cups, the self-sealing bag can be easily opened. The self-sealing bag is held and sealed by a fixed separating clamp and a movable sealing clamp, which is convenient, fast and automates the opening and sealing process.
[0040] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
