Description

Technical Field

[0001] This invention relates to the field of flexible bag packaging equipment with spouts, and more particularly to a spout feeding mechanism for flexible packaging bags and a vertical packaging machine. Background Technology

[0002] Flexible pouches with spouts are a type of packaging that features a special spout structure on a flexible packaging bag. This spout enables precise dispensing and airtight preservation, and is widely used in various fields such as food, daily chemicals, and pharmaceuticals. For example, it is used for packaging products such as sauces, laundry detergents, and nutritional drinks. It can effectively improve the convenience of product use and the airtightness of storage, meeting consumers' needs for product practicality and safety.

[0003] Currently, the production process for commonly available flexible packaging bags with spouts typically involves first creating semi-finished bags using a bag-feeding machine, then transferring these bags to specialized equipment to press the spouts into the bag body for final assembly. While this method ensures a precise fit between the spout and the bag body, it undoubtedly adds extra processing steps, making the entire production process more complex and inevitably extending the production cycle, thus impacting production efficiency. Furthermore, existing vertical packaging machines are primarily designed for spoutless flexible bags and are ill-suited for the production needs of flexible packaging bags with spouts, failing to achieve efficient and automated feeding and packaging for these bags.

[0024] Currently, the production process for commonly available flexible packaging bags with spouts typically involves first creating semi-finished bags using a bag-feeding machine, then transferring these bags to specialized equipment to press the spouts into the bag body for final assembly. While this method ensures a precise fit between the spout and the bag body, it undoubtedly adds extra processing steps, making the entire production process more complex and inevitably extending the production cycle, thus impacting production efficiency. Furthermore, existing vertical packaging machines are primarily designed for spoutless flexible bags and are ill-suited for the production needs of flexible packaging bags with spouts, failing to achieve efficient and automated feeding and packaging for these bags.

[0025] To address the aforementioned issues, this application provides a spout feeding mechanism for flexible packaging bags, which is compatible with vertical packaging machines to achieve efficient and automated production of flexible packaging bags with spouts. This not only significantly simplifies the production process but also effectively shortens the production cycle, greatly improving production efficiency and meeting the market demand for large-scale, efficient production of flexible packaging bags with spouts.

[0026] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings. Example 1

[0027] Please see Figures 1-8This application discloses a nozzle feeding mechanism for flexible packaging bags, comprising a frame 1, a vibration assembly 2, a slide assembly 3, a nozzle-picking assembly 4, and a sealing assembly 5. The vibration assembly 2 is disposed at the top of the frame 1 and is used to store nozzles 6, and to cause the nozzles 6 to enter the slide assembly 3 in an orderly manner through vibration. One end of the slide assembly 3 is connected to the output end of the vibration assembly 2, and the other end is provided with a loading station for conveying the nozzles 6 on the vibration assembly 2 to the loading station. The nozzle-picking assembly 4 is disposed on one side of the slide assembly 3 and faces the loading station, and is used to pick up the nozzles 6 on the loading station and place them at the sealing assembly 5. The sealing assembly 5 is disposed beside the nozzle-picking assembly 4 and is used to seal the nozzles 6 onto the flexible packaging bag.

[0028] Specifically, the vibration assembly 2 includes a vibrating plate and a vibrator; the vibrator is located at the bottom of the vibrating plate and is used to drive the vibrating plate to vibrate, so that the suction nozzles stored in the vibrating plate enter the slide assembly 3 in an orderly manner, which greatly reduces the risk of jamming or failure caused by disorderly placement, thereby ensuring the smooth operation and efficient operation of the entire system.

[0029] The slide assembly 3 includes a first slide section 31, a second slide section 32, and a third slide section 33. The first slide section 31 is inclined downwards, which helps the suction nozzle 6 to slide smoothly under its own weight. Preferably, the horizontal angle of the first slide section 31 is 15 degrees, ensuring the suction nozzle 6 slides smoothly without causing it to slide too fast and become disorganized due to an excessively large angle. The second slide section 32 is vertically positioned between the first slide section 31 and the third slide section 33, and is connected to both the first and third slide sections 31. Preferably, the connection points between the second slide section 32 and the first and third slide sections 31 are rounded, effectively preventing the suction nozzle 6 from getting stuck or damaged when passing through the connection points, thus making the entire suction nozzle 6 transport smoother. The third slide section 33 is horizontally disposed at the end of the second slide section 32, and the loading station is disposed on the third slide section 33, so that the suction nozzle 6 can smoothly reach the loading station, facilitating the material picking assembly 4 to pick up the material. Preferably, the third slide section 33 and the first slide section 31 are located on the same side of the second slide section 32, which facilitates the suction nozzle to rotate 180 degrees under the guidance of the slide assembly 3, facilitating the subsequent gripping by the material picking assembly 4.

[0030] For example, the first slide section 31, the second slide section 32, and the third slide section 33 include a slide body 331 and a receiving groove 332. The slide body 331 is fixed to the frame 1 by a fixing block to ensure the stability of the entire slide assembly 3. The receiving groove 332 is disposed on the inner side of the slide body 331 and is adapted to the shape of the suction nozzle 6. It is used to receive the suction nozzle 6 and guide the suction nozzle 6 to slide down, preventing the suction nozzle 6 from deviating from the track during the sliding process. For example, the receiving groove 332 includes a wide diameter portion and a narrow diameter portion. The wide diameter portion is used to receive the middle area of ​​the suction nozzle 6, and the narrow diameter portion is used to receive the edge area of ​​the suction nozzle 6, so as to better fit the shape of the suction nozzle 6 and improve the stability of the sliding. It should be noted that the specific shape of the receiving groove 332 can be determined according to the shape of the suction nozzle 6, and is not limited here. Furthermore, the slide assembly 3 also includes a baffle 34, which is disposed on the second slide section 32 and located on the opening side of the receiving groove 332, thereby forming a relatively sealed environment with the slide body 331 to prevent the suction nozzle 6 from detaching from the second slide section 32 and to ensure that the suction nozzle 6 can smoothly reach the third slide section 33.

[0031] The feeding nozzle assembly 4 includes a drive motor 41 and a finger cylinder 42. The drive motor 41 is fixed to the frame 1, and its output end is poweredly connected to the finger cylinder 42, providing power support to the finger cylinder 42. The finger cylinder 42 includes grippers 43, a pair of which are slidably disposed within a slide rail at the end of the finger cylinder 42, and the grippers 43 face the slide rail assembly 3 for gripping the suction nozzle 6 located on the slide rail assembly 3. To better grip the suction nozzle 6, the side of the gripper 43 used to grip the suction nozzle 6 is also provided with an arc surface adapted to the suction nozzle 6, and the arc surface is provided with anti-slip texture 431, thereby increasing the friction between the gripper 43 and the suction nozzle 6, preventing the suction nozzle 6 from slipping during gripping, and further improving the gripping stability. For example, the anti-slip texture 431 is toothed and adapted to the thread of the suction nozzle 6. When the suction nozzle 6 needs to be gripped, the drive motor 41 starts, driving the finger cylinder 42 to move. This moves the gripper 43 of the finger cylinder 42 to both sides of the loading station of the slide rail assembly 3. Then, the finger cylinder 42 actuates, causing the pair of grippers 43 to slide relative to each other along the slide rail and close until the arc surface with the anti-slip texture 431 tightly grips the suction nozzle 6 located at the loading station. After gripping the suction nozzle 6, the drive motor 41 actuates again, rotating the finger cylinder 42 holding the suction nozzle 6 180 degrees, causing the suction nozzle 6 to move to a predetermined position (i.e., the sealing station), facilitating the next step of sealing the suction nozzle 6 with the soft packaging bag.

[0032] The sealing assembly 5 includes a first sealing part 51 and a second sealing part 52, which are symmetrically arranged on the frame 1 and located on both sides of the flexible packaging bag. Each of the first sealing part 51 and the second sealing part 52 includes a drive cylinder 511, a sealing plate 512, and a heating element. The drive cylinder 511 is mounted on the frame 1, and its movable push rod is connected to the sealing plate 512, driving the sealing plate 512 to move towards the flexible packaging bag. The sealing plate 512 also has a buffer layer and a recess 5121. The buffer layer is located on the surface of the sealing plate 512 that contacts the flexible packaging bag, reducing the impact force of the sealing plate 512 on the flexible packaging bag and preventing damage. The recess 5121 is adapted to the suction nozzle 6, accommodating the nozzle 6 and ensuring that the nozzle 6 is accurately aligned with the installation position on the flexible packaging bag during the sealing process. The heating element is located inside the sealing plate 512. By heating, the sealing plate 512 generates sufficient heat to seal the nozzle 6 onto the flexible packaging bag, thus completing the production of the flexible packaging bag with the nozzle.

[0033] Furthermore, the flexible packaging bag nozzle feeding mechanism also includes a material detector and a controller. The material detector is located at the front end of the slide assembly 3 and is used to detect whether the slide assembly 3 is short or full of material. The controller is electrically connected to both the material detector and the vibrator of the vibration assembly 2, and is used to receive feedback signals from the material detector and control the start and stop of the vibration assembly 2 according to the feedback signals. When the material detector detects that the slide assembly 3 is short of material, it sends a signal to the controller. After receiving the signal, the controller starts the vibration assembly 2, allowing the nozzle to enter the slide assembly 3. When the slide assembly 3 is detected to be full of material, the controller will control the vibration assembly 2 to stop working to prevent excessive accumulation of the nozzle 6 and thus avoid affecting normal production.

[0034] Working principle: When the vibrator is activated, it drives the vibratory plate to vibrate, causing the suction nozzles 6 stored in the vibratory plate to enter the first slide section 31 in an orderly manner. Since the first slide section 31 is inclined downward, the suction nozzles 6 can smoothly slide down to the second slide section 32 by their own gravity. Then, guided by the second slide section 32, they fall vertically and enter the loading station of the third slide section 33 under the action of inertia. When the suction nozzles 6 reach the loading station, the drive motor 41 is activated, driving the finger cylinder 42 to move, so that the grippers 43 of the finger cylinder 42 can move to both sides of the loading station of the slide assembly 3. Then, the finger cylinder 42 actuates, causing a pair of grippers 43 to slide relative to each other along the slide rail and close until the arc surface with anti-slip texture 431 tightly clamps the suction nozzles 6 located at the loading station. After clamping the suction nozzle 6, the drive motor 41 actuates again, rotating the finger cylinder 42 holding the suction nozzle 6 by 180 degrees, so that the suction nozzle 6 moves to the preset sealing position. At this time, the driving cylinders 511 of the first sealing part 51 and the second sealing part 52 are started synchronously, driving the movable push rod to move the sealing plate 512 towards the flexible packaging bag. During the movement, the recess 5121 on the sealing plate 512 accurately accommodates the suction nozzle 6, ensuring that the suction nozzle 6 can be accurately aligned with the installation position on the flexible packaging bag during the sealing process. As the sealing plate 512 continues to move, the buffer layer on the sealing plate 512 comes into contact with the flexible packaging bag. At the same time, the heating element set in the sealing plate 512 generates enough heat to raise the temperature of the sealing plate 512. During the contact process between the sealing plate 512 and the flexible packaging bag and the suction nozzle 6, the contact part between the suction nozzle 6 and the flexible packaging bag is heated and melted by heat transfer, thereby realizing a firm seal between the suction nozzle 6 and the flexible packaging bag, and completing the production of the flexible packaging bag with suction nozzle.

[0035] Throughout the process, the material detector continuously monitors the material status within the slide assembly 3. Once a material shortage is detected, a signal is sent to the controller. Upon receiving the signal, the controller quickly activates the vibration assembly 2, causing the vibrating plate to vibrate and orderly feed new suction nozzles 6 into the slide assembly 3, ensuring continuous production. When a full material is detected, the controller promptly stops the vibration assembly 2 to prevent excessive accumulation of suction nozzles 6 from affecting normal production, ensuring that the entire flexible packaging bag suction nozzle feeding mechanism can operate stably and efficiently.

[0036] In this first embodiment, the flexible packaging bag spout feeding mechanism provided by this application includes a frame, a vibration assembly, a slide assembly, a feeding nozzle assembly, and a sealing assembly. Through their close cooperation, it can be adapted to a vertical packaging machine to achieve efficient and automated production of flexible packaging bags with spouts. This not only significantly simplifies the production process but also effectively shortens the production cycle, greatly improving production efficiency. By setting the horizontal angle of the first slide section to 15 degrees, the spout can be ensured to slide smoothly without causing confusion due to excessively fast descent speed caused by an excessively large angle. By making the connection points between the second slide section, the first slide section, and the third slide section rounded, the spout can be effectively prevented from getting stuck or damaged when passing through the connection points. By providing a baffle on the slide assembly, the spout can be prevented from detaching from the second slide section, ensuring that the spout smoothly reaches the third slide section. By providing an arc surface and anti-slip texture on the gripper adapted to the spout, the stability of gripping the spout is effectively improved. By incorporating a buffer layer on the sealing plate that contacts the flexible packaging bag, the impact force of the sealing plate on the flexible packaging bag is effectively reduced, preventing damage due to excessive impact. By installing a material detector and controller, the material condition within the slide assembly can be monitored in real time, and the vibration assembly can be started and stopped based on feedback signals, ensuring the continuity and stability of production.
