[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0035] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a follow-up structure for push-to-fill bag packaging for easy-open lids, including a translation guide rail 1 positioned above and parallel to the lid slide rail, and a first slide 2 and a second slide 3 slidably connected to the translation guide rail 1, and further including:
[0039] The first lifting cylinder 4 is fixedly installed at the end of the first slide block 2 away from the translation guide rail 1, and the second lifting cylinder 5 is fixedly connected to the outer wall of the second slide block 3 away from the translation guide rail 1.
[0040] Self-resetting push plate 6, which is installed on the lifting end of the first lifting cylinder 4;
[0041] Positioning plate 7 is installed on the lifting end of the second lifting cylinder 5;
[0042] Guide rail 8 is fixedly installed on the top of translation guide rail 1, and guide rail 8 is slidably engaged with first slide block 2;
[0043] The assembly plate 9 is fixedly connected to the outer side wall of the first slide block 2, and the mounting plate 11 is fixedly connected to the top of the assembly plate 9.
[0044] The drive mechanism is mounted on the mounting plate 11 and is used to drive the first slide 2 and the second slide 3 to move along the translation guide rail 1.
[0045] like Figure 3 and Figure 4 As shown, a U-shaped frame 13 is fixedly connected to the telescopic end of the first lifting cylinder 4. A slide rod 14 is fixedly connected between the vertical sections of the U-shaped frame 13. A self-resetting push plate 6 is slidably connected to the outer wall of the slide rod 14. A compression spring 10, sleeved on the outer wall of the slide rod 14, is fixedly connected between the self-resetting push plate 6 and the vertical section of the U-shaped frame 13. During movement, the control system, based on the position information of the easy-open can lid fed back by the sensor (if equipped with relevant position detection sensors), precisely controls the first lifting cylinder 4 to drive the self-resetting push plate 6 to descend to the contact position with the easy-open can lid. Under the action of the compression spring 10, the self-resetting push plate 6 is tightly attached to the easy-open can lid. When encountering easy-open can lids of different shapes or slightly offset, the self-resetting push plate 6 can adaptively adjust by compressing the compression spring 10 to avoid damage or displacement of the can lid.
[0046] like Figure 1 , Figure 2 and Figure 3 As shown, the drive mechanism includes a first drive chain 15 mounted on one side of the mounting plate and a second drive chain 16 mounted on the other side of the mounting plate. The working end of the first drive chain 15 is connected to the mounting plate 11, and the working end of the second drive chain 16 is connected to the second slide block 3, used to drive the second slide block 3 to slide along the translation guide rail 1. When the drive mechanism is activated, the first drive chain 15 and the second drive chain 16 begin to operate. Based on the utility model patent with patent number 202420356346.4, the drive mechanism of this structure adopts a chain drive method, which is more stable and easier to control than the original device's drive method. The first drive chain 15 drives the first slide block 2 to move along the translation guide rail 1, while the second drive chain 16 drives the second slide block 3 to move along the translation guide rail 1.
[0047] like Figure 1 , Figure 2 and Figure 3 As shown, the middle section of the assembly plate 9 is fixedly connected to a limiting guide rail 17 parallel to the guide rail 8. The second slide block 3 is slidably engaged with the limiting guide rail 17. The limiting guide rail 17 is slidably engaged with the translation guide rail 1. The outer side wall of the second slide block 3 is fixedly connected to a positioning rod 12.
[0048] like Figure 2 and Figure 3As shown, a positioning seat 18 is detachably connected to the outer wall of the limiting guide rail 17. A limiting post 19 is fixedly connected to the side of the positioning seat 18 away from the limiting guide rail 17, located on the path of the second slide 3 along the translation guide rail 1. The positioning plate 7 maintains the positioning of the easy-open can lid. Its synergistic effect with the self-resetting push plate 6 allows it to better adapt to different sizes of packaging bags compared to the original patented device, ensuring that the easy-open can lid is accurately inserted into the bag. When the second slide 3 moves to the position of the limiting post 19, the pressure sensor detects the pressure change and sends a feedback signal to the control system.
[0049] like Figure 2 and Figure 3 As shown, a pressure sensor is installed on the side of the second slide 3 near the limiting post 19. After receiving the signal from the pressure sensor, the control system compares it with a preset pressure threshold, which can be adjusted in the control system according to actual production needs. If the pressure reaches or exceeds the threshold, it indicates that the second slide 3 has reached the predetermined position, and the control system immediately controls the drive mechanism to stop running, completing one push-cap-in-bag operation. In the utility model patent with patent number 202420356346.4, the swing component and the bag-in-bag component work together to send the moving easy-open can cap into the paper bag.
[0050] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes a control system, which is connected to the drive mechanism, the first lifting cylinder 4, the second lifting cylinder 5, and the pressure sensor.
[0051] Specifically, the push-cap bag insertion following structure used for easy-open packaging operates as follows: each component of the push-cap bag insertion following structure is installed in the corresponding position on the easy-open packaging production line according to the design requirements, ensuring that each component, such as the translation guide rail 1, the first slide 2, the second slide 3, the first lifting cylinder 4, and the second lifting cylinder 5, is firmly installed and tightly connected.
[0052] Connect the drive mechanism, the first lifting cylinder 4, the second lifting cylinder 5, and the pressure sensor and control system to ensure stable and accurate signal transmission;
[0053] The equipment was debugged, and parameters such as the operating speed of the drive mechanism and the lifting stroke of the first lifting cylinder 4 and the second lifting cylinder 5 were set through the control system. The operation of each component was checked to ensure that each component could operate normally and cooperate with each other. The equipment was then tested, and the status of the easy-open can lid during the process of pushing the lid into the bag was observed. The parameters were fine-tuned according to the actual situation until the equipment operated stably and reliably.
[0054] Easy-open can lids are transported to a designated position via a lid slide. In the utility model patent with patent number 202420356346.4, the lid slide is an important channel for transporting easy-open can lids, which are arranged in an orderly manner on the slide and await being pushed. At the same time, the packaging bag is also placed in a suitable position, waiting for the lid to be pushed into the bag.
[0055] At this time, the control system controls the first lifting cylinder 4 and the second lifting cylinder 5 according to the preset program, so that the self-resetting push plate 6 and the positioning plate 7 are in the initial rising position to avoid interference with the easy-open can lid and the packaging bag.
[0056] The drive mechanism is activated, and the first drive chain 15 and the second drive chain 16 begin to operate. Based on the utility model patent with patent number 202420356346.4, the drive mechanism of this structure adopts a chain drive method, which is more stable and easier to control compared to the original device's drive method. The first drive chain 15 drives the first slide 2 to move along the translation guide rail 1, while the second drive chain 16 drives the second slide 3 to move along the translation guide rail 1.
[0057] During the movement, the control system, based on the position information of the easy-open can lid fed back by sensors (if equipped with relevant position detection sensors), precisely controls the first lifting cylinder 4 to drive the self-resetting push plate 6 to descend to the contact position with the easy-open can lid. Under the action of the compression spring 10, the self-resetting push plate 6 is in close contact with the easy-open can lid. When encountering easy-open can lids of different shapes or slightly offset, the self-resetting push plate 6 can adaptively adjust by compressing the compression spring 10 to avoid damage or displacement of the can lid.
[0058] Simultaneously, the second lifting cylinder 5 drives the positioning plate 7 to descend, positioning the easy-open can lid. The positioning action of the positioning plate 7 works in conjunction with the lid-pushing action of the self-resetting push plate 6, ensuring more precise stability of the easy-open can lid during the lid-pushing process compared to the original patented device, preventing it from tipping over or shifting.
[0059] As the first slide 2 and the second slide 3 continue to move, the self-resetting pusher 6 pushes the easy-open can lid toward the packaging bag. During the pushing process, the self-resetting pusher 6 is continuously subjected to the action of the compression spring 10, maintaining stable contact with the easy-open can lid and ensuring that the pushing force is uniform and the direction is accurate.
[0060] The positioning plate 7 maintains the position of the easy-open can lid. Its synergistic effect with the self-resetting push plate 6 allows it to better adapt to different sizes of packaging bags compared to the original patented device, ensuring that the easy-open can lid is accurately inserted into the bag. When the second slide 3 moves to the position of the limit post 19, the pressure sensor detects the pressure change and sends a feedback signal to the control system.
[0061] After receiving the signal from the pressure sensor, the control system compares it with a preset pressure threshold, which can be adjusted in the control system according to actual production needs. If the pressure reaches or exceeds the threshold, it indicates that the second slide 3 has reached the predetermined position, and the control system immediately controls the drive mechanism to stop running, completing one push-cap-in-bag operation. In the utility model patent with patent number 202420356346.4, the swing component and the bag-in-bag component work together to send the moving easy-open can lid into the paper bag.
[0062] The first lifting cylinder 4 and the second lifting cylinder 5 drive the self-resetting push plate 6 and the positioning plate 7 to rise and reset according to the instructions of the control system, returning to the initial position, and preparing for the next operation of pushing the cap into the bag.
[0063] The drive mechanism reverses its direction, driving the first slide 2 and the second slide 3 back to their initial positions. During the reset process, the control system monitors the movement status of each component in real time to ensure accurate reset and avoid positional deviations that could affect the next operation.
[0064] All technical features in this embodiment can be freely combined according to actual needs.
[0065] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
