In the process of fine processing of aquatic products, multi-row back-sealing packaging machines are widely used to package aquatic products, such as fish roe pellets.

[0003] Traditional multi-row back-seal packaging machines work by conveying multiple sets of packaging bags into their respective forming chambers for forming. After forming, fish roe pellets are added into the packaging bags, and the bags are sealed with heat-sealing strips to package the fish roe pellets. However, when the packaging machine moves the packaging bag, the overall vibration of the machine may cause the packaging bag to shift, making it impossible to ensure the sealing of the packaging bag during heat sealing. This affects the packaging effect of the fish roe pellets and reduces the working efficiency of the multi-row back-sealing packaging machine. Utility Model Content

This device solves the problem that when the packaging machine moves the packaging bag, the vibration of the entire machine may cause the packaging bag to shift, resulting in the inability to ensure the alignment of the packaging bag during heat sealing and reducing the working efficiency of the multi-row back-sealing packaging machine.

[0011] Beneficial effects This utility model provides an integrated device for efficient sealing and precise positioning in a multi-row back-sealing packaging machine. It offers the following advantages: This integrated device, through the cooperation of uprights, horizontal columns, rotating rollers, and mounting columns, achieves precise positioning of the moving packaging bag.

[0015] 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.

[0016] When the packaging machine moves the packaging bag, the overall vibration of the machine may cause the packaging bag to shift, which may result in the packaging bag not being able to be aligned during heat sealing, thus reducing the working efficiency of the multi-row back-sealing packaging machine.

[0017] In view of this, the present invention provides an integrated device for efficient sealing and precise positioning of multi-row back-sealing packaging machine. Through the cooperation between the upright column, the horizontal column, the rotating roller and the mounting column, the device can position the moving packaging bag. This solves the problem that when the packaging machine moves the packaging bag, the position of the packaging bag may be offset due to the vibration of the whole machine, which may cause the packaging bag to be misaligned during heat sealing and reduce the working efficiency of the multi-row back-sealing packaging machine.

[0018] Those skilled in the art will connect the electrical components and their compatible power supplies in this case using wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle below, where the electrical components are connected in the order of operation. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.

[0019] Example 1, by Figure 1-6 It is understood that the multi-row back-sealing packaging machine in this case has an integrated device for efficient sealing and precise positioning, including a vertical plate 1, a heat-sealing plate 28 fixedly connected to the lower front of the vertical plate 1, a heat-sealing strip 15 provided on the front of the heat-sealing plate 28, an installation column 19 provided on the upper front of the vertical plate 1, and a column 16 fixedly connected to the front of the installation column 19 by bolts. There are two columns 16, and the top and bottom of the two columns 16 are respectively fixedly connected to a horizontal column 17 by bolts. The inner walls of the two columns 16 are rotatably connected to a rotating roller 18 through a bearing. In the specific implementation process, it is worth noting that the heat-sealing plate 28 is made of 6061 aluminum alloy with excellent thermal conductivity and high temperature resistance, while the heat-sealing strip 15 is made of nickel-chromium alloy with high resistivity and good oxidation resistance. The heat-sealing plate 28 and the heat-sealing strip 15 are connected to the external controller through high-temperature shielded wires, which can realize precise control of parameters such as heat-sealing temperature and time. The upright column 16 and the horizontal column 17 can be made of polycarbonate (PC) engineering plastic, and the rotating roller 18 can be made of ultra-high molecular weight polyethylene (UHMWPE) engineering plastic. The heat-sealing plate 28 is connected to the upright plate 1 by bolts. The operator can rotate the bolts to disassemble and install the heat-sealing plate 28 for maintenance. The surface of the upright plate 1 is provided with mounting holes. The operator fixes the upright plate 1 to the external multi-row back-sealing packaging machine through the mounting holes. Then, the operator places the horizontal column 17 on the upright column 16 and rotates the corresponding bolts to fix the two. After that, the upright column 16 on the back is fixed to the mounting column 19 with bolts to assemble the positioning structure. After that, the multi-row back-sealing packaging machine starts to work, moving the sealing position of the packaging bag containing fish roe particles between the heat sealing plate 28 and the heat sealing strip 15. The packaging bag is sealed by the heat sealing plate 28 and the heat sealing strip 15. When the packaging bag moves, it is blocked by the adjacent two-sided rotating rollers 18 to achieve positioning of the moving packaging bag. Furthermore, the back of the upright plate 1 is fixedly connected to the box 20. The upper part of the inner wall of the box 20 is rotatably connected to the rotating column 21 via a bearing. The rotating column 21 is rotatably connected to the double-ended stud 23 via a bevel gear set 22. Both ends of the double-ended stud 23 are rotatably connected to the inner wall of the box 20 via bearings. The outer wall of the double-ended stud 23 is threadedly connected to the threaded block 24. The front of the threaded block 24 is fixedly connected to the connecting plate 25. The front of the connecting plate 25 is fixedly connected to the connecting column 26. The connecting column 26 penetrates the upright plate 1 and is movably connected to the upright plate 1. The end of the connecting column 26 is fixedly connected to the back of the mounting column 19. In the specific implementation process, it is worth noting that the housing 20 can be connected to the upright plate 1 by bolts. The bevel gear set 22 includes a first bevel gear and a second bevel gear. The first bevel gear is fixed to the bottom of the rotating column 21. The second bevel gear is meshed with the bottom of the first bevel gear. The second bevel gear is fixed to the outer wall of the double-headed stud 23. When packaging fish roe pellets with bags of different sizes, the operator first rotates the rotating column 21. The rotating column 21 drives the bevel gear set 22 to rotate, which in turn drives the double-ended stud 23 to rotate. The double-ended stud 23 drives the threaded block 24 to move, which in turn drives the connecting plate 25 to move. The connecting plate 25 then drives the connecting column 26 to move. The connecting column 26 moves within the vertical plate 1, thus limiting its position. The connecting column 26 then drives the mounting column 19 to move, thereby moving the adjacent rotating rollers 18 on both sides. After the movement is complete, the operator stops rotating the rotating column 21, thereby adjusting the distance between the adjacent rotating rollers 18 on both sides and positioning the bags of different sizes. Furthermore, the top of the rotating column 21 is provided with a scale line 27, and the top of the housing 20 is fixed with a pointer 2; In the specific implementation process, it is worth noting that when the operator rotates the rotating column 21, the rotating column 21 drives the scale line 27 on its surface to rotate. At this time, by observing the relative position of the scale line 27 and the pointer 2, the operator can accurately control the adjustment amount of the rotating roller 18. Furthermore, a horizontal plate 3 is fixedly connected to the lower back of the vertical plate 1, and a reinforcing rib 4 is fixedly connected between the vertical plate 1 and the horizontal plate 3. A hydraulic cylinder 5 is fixedly connected to the surface of the horizontal plate 3 by bolts. A sleeve 6 is sleeved on the output end of the hydraulic cylinder 5. The outer wall of the sleeve 6 is fixedly connected to the side of the vertical plate 1 near the heat-sealing plate 28. A connecting lug 7 is fixedly connected to the output end of the hydraulic cylinder 5 by bolts. A housing 10 is fixedly connected to the side wall of the connecting lug 7. In the specific implementation process, it is worth noting that a synchronizer is installed between the two hydraulic cylinders 5. The synchronizer adopts a mechanical synchronization valve. The mechanical synchronization valve ensures that the two hydraulic cylinders 5 can move synchronously by precisely controlling the flow of oil entering the two hydraulic cylinders 5. The model of hydraulic cylinder 5 is HSG-80 / 50-100. The connection between hydraulic cylinder 5 and external controller is that the displacement sensor, pressure sensor and other feedback elements on hydraulic cylinder 5 are connected to the controller through a shielded cable so as to monitor the position, pressure and other working status parameters of hydraulic cylinder 5 in real time. At the same time, the controller sends electrical signals to the solenoid directional valve, proportional speed control valve and other actuators of hydraulic cylinder 5 through the control cable, thereby precisely controlling the extension and retraction, speed and pressure of hydraulic cylinder 5, realizing precise control of the working process of heat sealing strip 15, and ensuring the efficient and stable operation of packaging machine. The reinforcing rib 4 strengthens the connection between the vertical plate 1 and the horizontal plate 3, improving the stability of the overall structure. When the packaging bag containing fish roe pellets moves between the heat sealing plate 28 and the heat sealing strip 15, the controller first activates the heat sealing plate 28 and the heat sealing strip 15, and then the controller activates the hydraulic cylinder 5. The hydraulic cylinder 5 drives its output end to move in the sleeve 6, and the hydraulic cylinder 5 drives the connecting ear 7, thereby driving the heat sealing strip 15 to move, so that the heat sealing plate 28 and the heat sealing strip 15 contact the sealing position of the packaging bag, and begin to seal the packaging bag. After completion, the controller causes the hydraulic cylinder 5 to retract, so that the heat sealing strip 15 moves to the initial position. After completion, the controller stops the hydraulic cylinder 5, thus sealing the packaging bag. Furthermore, a rubber ring 11 is fixedly connected to the inner wall of the housing 10, and a connecting rod 12 is attached to the inner wall of the rubber ring 11. The connecting rod 12 passes through the housing 10 and is movably connected to the housing 10. The beginning end of the connecting rod 12 is fixedly connected to the back of the heat sealing strip 15, and the end of the connecting rod 12 is fixedly connected to a connecting piece 13. A spring 14 is fixedly connected between the heat sealing strip 15 and the housing 10, and the spring 14 is sleeved on the outer wall of the connecting rod 12. In the specific implementation process, it is worth noting that the rubber ring 11 is made of nitrile rubber, and the model of the spring 14 is selected according to the actual situation to meet the working conditions. During the movement of the heat sealing strip 15, the heat sealing strip 15 drives the connecting rod 12 to move in the housing 10, limiting the connecting rod 12. The connecting rod 12 drives the connecting piece 13 to move, and the heat sealing strip 15 squeezes the spring 14, so that the hydraulic cylinder 5 provides a certain buffer when pushing the heat sealing strip 15 to move, making the contact of the heat sealing strip 15 more stable. After completion, the spring 14 rebounds, so that the heat sealing strip 15 returns to the initial position. When spring 14 is subjected to force, it deforms. During this process, spring 14 will repeatedly rebound. Through the friction between connecting rod 12 and rubber ring 11, the kinetic energy of this part is consumed, which plays a damping role. Example 2, by Figure 1-3It can be seen that a vertical block 8 is fixedly connected to the bottom of the connecting ear 7, and the back of the vertical block 8 is fixedly connected to the slide rod 9. The slide rod 9 passes through the vertical plate 1 and is movably connected to the vertical plate 1. In the specific implementation process, it is worth noting that when the hydraulic cylinder 5 drives the heat sealing strip 15 to move, the connecting ear 7 drives the upright block 8 to move, the upright block 8 drives the slide rod 9 to move, and the slide rod 9 moves in the upright plate 1 to support the heat sealing strip 15 when it moves, thereby making the movement of the heat sealing strip 15 more stable.
