[0020] The present invention also provides a device for attaching a packaging liquid packaging straw and a method for attaching the same, comprising the following steps: S1, by placing the liquid packaging box and the straw on the packaging box conveyor 1 and the straw conveyor 2 respectively for conveying, when the liquid packaging box is released to the squeezing plate 412, the touch switch 48 will be automatically turned on and the dispensing cylinder 42 will be started; S2, by starting the glue dispensing cylinder 42, the glue dispensing gun 45 can be pushed toward the liquid packaging box. When the glue dispensing gun 45 contacts the liquid packaging box, the glue dispensing operation can be automatically performed on the surface of the liquid packaging box; S3, after the glue dispensing operation is completed, the glue dispensing gun 45 is reset under the drive of the glue dispensing cylinder 42, and then the lifting push rod 46 contracts and drives the blocking frame 47 to rise, so that the squeezing plate 412 rises synchronously, and the liquid packaging box is released from the blocking, and then the liquid packaging box continues to be conveyed forward on the packaging box conveyor 1; S4, during the dispensing process, the straws are transported on the straw conveyor 2. By starting the traverse push rod 55, the bonding cylinder 56 and the clamping seat 512 and its auxiliary structures can be pulled close to the straw conveyor 2. Then, the bonding cylinder 56 and the clamping cylinder 513 are successively started to clamp the straws on the surface of the straw conveyor 2. S5. After the straws are clamped and loaded, the bonding cylinder 56 and the lateral push rod 55 will reset automatically, and the clamping claw 517 and the clamped straws can be transferred to the top of the packaging box conveyor 1, waiting for the arrival of the liquid packaging box after dispensing; S6, when the glued liquid packaging box moves and the second touch switch 511 is turned on, the bonding cylinder 56 starts and pushes the fixed plate 57 down again, thereby driving the clamping claw 517 and the clamped straw to move down synchronously, and the straw can be automatically bonded to the glued position on the liquid packaging box; S7, after the adhesion operation is completed, the clamping cylinder 513 then moves in the reverse direction, and the clamping claw 517 is restored to its initial open state under the action of the spring 2 518, and then the transverse push rod 55 is started again, thereby driving the fixed plate 57, the connecting frame 58 and the pushing plate 59 to move synchronously, so that the liquid packaging box after the straw adhesion is completed can be pushed out from the surface of the packaging box conveyor 1. At the same time, the movement of the fixed plate 57 can also transport the clamping claw 517 to the top of the straw conveyor 2 again for clamping and loading.

[0021] Working principle: when it is necessary to perform adhesion operation between the liquid packaging box and the straw, first place the liquid packaging box and the straw on the packaging box conveyor 1 and the straw conveyor 2 respectively for transportation. As the liquid packaging box is transported, when the liquid packaging box reaches the position of the squeezing plate 412, it can push the squeezing plate 412 to drive the sliding block 410 to slide on the surface of the blocking slide bar 49, thereby stretching the spring 1 411 to deform and generate elastic force. When the liquid packaging box reaches the dispensing position, the sliding block 410 just contacts and turns on the touch switch 1 48, and then the dispensing cylinder 42 can be automatically started to push the push plate 43 to move downward along the push slide rail 44, thereby driving the dispensing gun 45 to approach the surface of the liquid packaging box. When the dispensing gun 45 contacts the liquid packaging box, the dispensing gun 45 starts to dispense glue. , it can automatically perform glue dispensing operations on the surface of the liquid packaging box, and can automatically start the glue dispensing cylinder 42 according to the position of the liquid packaging box, so as to accurately determine the starting point of glue dispensing, and realize accurate positioning of the liquid packaging box at the glue dispensing position, effectively avoiding the problem of inaccurate glue dispensing position caused by the position deviation of the packaging box, greatly improving the consistency and quality stability of the product, and the entire glue dispensing process does not require manual intervention, which greatly improves the degree of automation of production, making the entire adhesion process smoother and more efficient. After completing the glue dispensing operation, the glue dispensing gun 45 is reset under the drive of the glue dispensing cylinder 42, and then the lifting push rod 46 contracts and drives the blocking frame 47 to rise, so that the extrusion plate 412 rises synchronously, and the obstruction to the liquid packaging box is released, and then the liquid packaging box continues to be conveyed forward on the packaging box conveyor 1.

[0022] Furthermore, during this period, the straws are transported on the straw conveyor 2. When the straws are transported to the discharge end of the straw conveyor 2, they will stop there. Then the transverse push rod 55 pulls the movable seat 54 to move along the transverse slide rail 53, so that the bonding cylinder 56 and the clamping seat 512 and their attached structures are close to the straw conveyor 2. When the clamping seat 512 moves to the position of the straw, the transverse push rod 55 is closed, and the bonding cylinder 56 and the clamping cylinder 513 are opened successively. By starting the bonding cylinder 56, the fixed plate 57 can be pushed down, thereby driving the clamping seat 512 and the clamping claw 517 to move downward synchronously. When the clamping claw 517 moves down to the position of the straw, the start of the clamping cylinder 513 can pull the push-pull ring 514 in the clamping The seat 512 slides in the push-pull groove inside the seat 512, and the push-pull ring 514 drives the toggle block 515 to rotate around the hinge shaft 516, so that the clamping claw 517 slides in the clamping seat 512 and approaches each other, thereby compressing the spring 2 518, and the straws stopped on the surface of the straw conveyor 2 can be clamped. After the clamping and loading of the straws are completed, the bonding cylinder 56 and the transverse push rod 55 will reset themselves, and the clamping claw 517 and the straws clamped by it can be transferred to the top of the packaging box conveyor 1, waiting for the arrival of the liquid packaging box after glue dispensing, and the straws at the discharge end of the straw conveyor 2 can be accurately grasped and transferred to the designated position above the packaging box conveyor 1, thereby reducing the adhesion defect rate caused by inaccurate straw placement and ensuring product quality.

[0023] Furthermore, when the glued liquid packaging box moves and contacts the touch switch 2 511 on the blocking plate 510, the conveying will be stopped to determine the bonding position, thereby ensuring that the bonding position of the straw and the liquid packaging box is accurate, avoiding bonding deviation caused by human judgment or operational errors, ensuring the bonding quality and consistency of the product, and effectively reducing the defective rate. The touch switch 2 511 is automatically turned on, and then the bonding cylinder 56 is immediately started to push the fixed plate 57 down again, thereby driving the clamping claw 517 and the clamped straw to move downward synchronously and approach the surface of the liquid packaging box after glue is dispensed. When the straw contacts the liquid packaging box, the straw can be automatically bonded to the glued position on the liquid packaging box to complete the bonding operation. Then the clamping cylinder 513 moves in the opposite direction, and the clamping claw 517 returns to the initial open state under the action of the spring 2 518, preparing for the next clamping. The device is ready to take out, which greatly improves the clamping efficiency of the equipment and the smoothness of the circulation operation. Then the transverse push rod 55 will start again, and then push the movable seat 54 to drive the fixed plate 57 to move. At this time, with the movement of the fixed plate 57, the connecting frame 58 and the pushing plate 59 can be driven to move synchronously, and then the liquid packaging box after the straw adhesion is completed is pushed out from the surface of the packaging box conveyor 1, so that it falls on the surface of the lower hopper 51 and slides down, waiting for further processing. When the fixed plate 57 moves to the top of the straw conveyor 2 again, the straws subsequently transported by the straw conveyor 2 will be clamped and loaded again by the clamping claw 517. Such a cycle can realize the full automation of the bonding process of the liquid packaging box and the straw, without manual intervention, greatly improving the production efficiency, reducing the errors and inconsistencies that may be caused by manual operation, and ensuring the stable and reliable bonding quality of each product.

[0024] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

A method for using the device for attaching a packaging straw to packaging liquids according to any one of claims 1 to 7, characterized in that: The following steps are involved: S1, placing the liquid packaging box and the straw on the packaging box conveyor (1) and the straw conveyor (2) respectively for conveying, when the liquid packaging box is released to the squeezing plate (412), the touch switch 1 (48) will be automatically turned on and the dispensing cylinder (42) will be started; S2, by starting the glue dispensing cylinder (42), the glue dispensing gun (45) can be pushed toward the liquid packaging box, and when the glue dispensing gun (45) contacts the liquid packaging box, the glue dispensing operation can be automatically performed on the surface of the liquid packaging box; S3, after the glue dispensing operation is completed, the glue dispensing gun (45) is reset under the drive of the glue dispensing cylinder (42), and then the lifting push rod (46) contracts and drives the blocking frame (47) to rise, so that the squeezing plate (412) rises synchronously, and the blocking of the liquid packaging box is released, and then the liquid packaging box continues to be conveyed forward on the packaging box conveyor (1); S4, during the dispensing process, the straws are transported on the straw conveyor (2), and by starting the transverse push rod (55), the bonding cylinder (56) and the clamping seat (512) and their attached structures are pulled close to the straw conveyor (2), and then the bonding cylinder (56) and the clamping cylinder (513) are successively started to clamp the straws on the surface of the straw conveyor (2); S5. After the straws are clamped and loaded, the bonding cylinder (56) and the lateral push rod (55) will reset themselves, and the clamping claw (517) and the clamped straws can be transferred to the top of the packaging box conveyor (1) to wait for the arrival of the liquid packaging box after dispensing; S6, when the glue-dispensed liquid packaging box moves and the second touch switch (511) is turned on, the bonding cylinder (56) starts and pushes the fixed plate (57) down again, thereby driving the clamping claw (517) and the clamped straw to move down synchronously, so that the straw can be automatically bonded to the glue-dispensed position on the liquid packaging box; S7, after the adhesion operation is completed, the clamping cylinder (513) then moves in the reverse direction, and the clamping claw (517) is restored to its initial open state under the action of the second spring (518), and then the transverse push rod (55) is started again, thereby driving the fixed plate (57), the connecting frame (58) and the pushing plate (59) to move synchronously, so that the liquid packaging box after the straw adhesion is completed can be pushed out from the surface of the packaging box conveyor (1). At the same time, the movement of the fixed plate (57) can also transport the clamping claw (517) to the top of the straw conveyor (2) again for clamping and loading.
