Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a feeding mechanism for a stand-up pouch sealing machine. Background Technology

[0002] Stand-up pouches are a highly practical form of packaging, typically consisting of two main parts: the pouch body and the spout. The pouch body, the primary component, is responsible for containing and protecting the product inside. It's usually made of plastic, paper, or other suitable materials to ensure the product's safety and freshness. The spout, located at the top of the pouch, allows the user to easily control the flow of the product and is commonly used for liquid or semi-liquid products such as beverages and sauces. This design not only makes it convenient for consumers but also makes products more appealing on store shelves, as stand-up pouches can stand independently without additional support.

[0003] In the production process of stand-up pouches, sealing equipment is used to attach the nozzles to the pouch body. However, in small-batch production, each nozzle needs to be manually fed to the sealing position one by one. Therefore, it is necessary to design a feeding mechanism for the stand-up pouch sealing machine. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a feeding mechanism for a stand-up pouch sealing machine.

[0005] The objective of this utility model can be achieved through the following technical solution: A feeding mechanism for a self-standing bag sealing machine includes a vertical plate and a mounting rod. The mounting rod is characterized by a vertically fixed storage tube for storing nozzles. The storage tube has a through-structure, with gripping notches on the left and right sides of its lower end. Multiple elastic support blocks are installed on the front and rear sides of the lower end of the storage tube. The lower end of the storage tube also has a pressing module for holding the nozzles. A servo motor is horizontally mounted on the vertical plate. A turntable is mounted on the output shaft end of the servo motor. A switching arm is connected to the turntable. A pen-type cylinder is mounted on the switching arm. A finger cylinder for gripping the nozzles is connected to the piston rod end of the pen-type cylinder.

[0006] The fingertip of the finger cylinder is also equipped with a clamping block that matches the grasping notch.

[0007] The pressing module includes a cylinder and a pressing head. The cylinder is horizontally mounted on the storage tube, and the pressing head is mounted on the piston rod end of the cylinder and can extend into the storage tube.

[0008] The pen-type cylinder is mounted on the switching arm via a fixing block, and the finger cylinder is connected to the piston rod end of the pen-type cylinder via a connecting block.

[0009] The turntable is also equipped with a detection plate, and the upright plate is also equipped with an upper photoelectric switch and a lower photoelectric switch that cooperate with the detection plate.

[0010] Compared with existing technologies, the feeding mechanism of this self-standing bag sealing machine has the following advantages:

[0011] In this invention, the suction nozzle is simply placed into the storage tube as required, and the suction nozzle at the bottom of the storage tube is clamped and rotated 90 degrees until it is sealed. This eliminates the need for manual handling of each suction nozzle, greatly simplifying the feeding process. Attached Figure Description

Detailed Implementation

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figures 1-4As shown, the feeding mechanism of this self-standing bag sealing machine includes a vertical plate 1 and a mounting rod 8. In practice, the sealing machine uses existing semi-automatic equipment. Both the vertical plate 1 and the mounting rod 8 are mounted on the machine frame. A storage tube 5 for storing nozzles is vertically fixed on the mounting rod 8. In practice, the nozzles are vertically inserted into the storage tube 5 with their openings facing downwards. The storage tube 5 has a through-structure. Grabbing notches 5a are provided on the left and right sides of the lower end of the storage tube 5. Multiple elastic support blocks 5b are installed on the front and rear sides of the lower end of the storage tube 5. Under normal circumstances, due to the action of the elastic support blocks 5b, the nozzles will not fall out from the bottom of the storage tube 5. After the clamping block 11 clamps the bottom nozzle of the storage tube 5, the pen-type cylinder 3 moves it downwards, and the clamping block 11 grabs the nozzle out of the storage tube 5. The second nozzle at the bottom can be held by the pressure head 10 to prevent it from falling out accidentally. The storage tube 5 The lower end also has a holding module for holding the suction nozzle. A servo motor 7 is horizontally mounted on the upright plate 1. A turntable 2 is mounted on the output shaft end of the servo motor 7. A switching arm 6 is connected to the turntable 2. With this structure, the servo motor 7 can drive the turntable 2 to rotate, and the turntable 2 can drive the switching arm 6 to rotate, so that the switching arm 6 can switch back and forth between a horizontal state and a vertical state. A pen-type cylinder 3 is mounted on the switching arm 6. A finger cylinder 4 for gripping the suction nozzle is connected to the piston rod end of the pen-type cylinder 3. With this structure, when the switching arm 6 is in a vertical state, the piston rod of the pen-type cylinder 3 extends, driving the finger cylinder 4 to move upward. The finger cylinder 4 grips the suction nozzle in the storage tube 5. When the piston rod of the pen-type cylinder 3 retracts, the switching arm 6 rotates 90 degrees and the switching arm 6 is in a horizontal state. The piston rod of the pen-type cylinder 3 extends, driving the finger cylinder 4 to move horizontally and sending the suction nozzle into the sealing position.

[0019] The finger tip of the finger cylinder 4 is also equipped with a clamping block 11 that cooperates with the grasping notch 5a.

[0020] The holding module includes a cylinder 9 and a pressure head 10. The cylinder 9 is horizontally mounted on the storage tube 5, and the pressure head 10 is mounted on the piston rod end of the cylinder 9. The pressure head 10 can extend into the storage tube 5. With this structure, before gripping, the cylinder 9 drives the pressure head 10 to extend, and the pressure head 10 holds the second suction nozzle at the bottom of the storage tube 5. After gripping, the pressure head 10 is in the released state, and the suction nozzle in the storage tube 5 moves downward and abuts against the elastic support block 5b.

[0021] The pen-type cylinder 3 is mounted on the switching arm 6 via the fixing block 12, and the finger cylinder 4 is connected to the piston rod end of the pen-type cylinder 3 via the connecting block 13.

[0022] The turntable 2 is also equipped with a detection plate 16, and the vertical plate 1 is also equipped with an upper photoelectric switch 14 and a lower photoelectric switch 15 that cooperate with the detection plate 16. This adopts existing technology, so that the position status of the switching arm 6 can be known.

[0023] In this invention, the suction nozzle is simply placed into the storage tube 5 as required, and the suction nozzle at the bottom of the storage tube 5 is clamped and rotated 90 degrees by the clamping block 11 until the sealing position is reached. This eliminates the need for manual handling of each suction nozzle, greatly simplifying the feeding process.

[0024] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
