Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a type-changing adjustment device for packaging machines. Background Technology

[0002] When adjusting packaging machines, a type of adjustment device is often used. This device allows for quick and precise adjustments to the packaging machine when packaging products of different specifications and models. It can significantly shorten changeover time, improve production efficiency, reduce equipment downtime, and lower labor and time costs. It can also ensure the accuracy and consistency of packaging for different products, improve product quality, enhance the packaging machine's adaptability to multiple product specifications, and increase equipment utilization.

[0003] The packaging machine's mold changeover adjustment device works as follows: First, the operator inputs the product information to be packaged. Then, the machine parameters, such as conveyor belt speed and sealing temperature, are adjusted according to the product specifications. Next, the cylinder actuator automatically changes the corresponding mold. After that, the packaging machine is started for trial operation. Once it is confirmed to be correct, it is put into formal production, achieving fast and accurate mold changeover packaging operations.

[0004] Existing technologies include some changeover adjustment devices for packaging machines. Current packaging machine changeover adjustments mainly rely on manual operation or semi-automatic adjustment methods. In manual adjustment mode, operators need to manually adjust the packaging machine and materials, such as the spacing of the feeding mechanism, the position of the sealing and cutting device, and the size of the forming mold. This is not only time-consuming and labor-intensive, but the adjustment accuracy also heavily depends on the operator's experience and skills, easily leading to unqualified packaging due to adjustment errors, increasing material waste and rework costs. Furthermore, for complex packaging machines, manual adjustment involves many components, and the changeover process often requires a long downtime, significantly reducing the continuous operating efficiency of the production line. Therefore, a changeover adjustment device for packaging machines is proposed to solve the above problems. Utility Model Content

After the partition plate is separated, it rises up and, together with the continuous conveying of the conveyor belt, realizes the smooth connection of the sealing and cutting cycle, effectively improving the efficiency of the overall packaging operation.

[0032] 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.

[0033] Reference Figures 1 to 3 An embodiment of this utility model is provided: a type-changing adjustment device for a packaging machine, including a support 1, which plays the role of bearing and transmitting force. A conveyor belt 23 is fixedly connected inside the support 1. During operation, the conveyor belt 23 rotates at a certain speed and direction to transport the material to be packaged from the input end of the packaging machine to the packaging station. A packaging mechanism is provided on the top of the support 1, and a partition sealing and cutting mechanism is provided on the top right side of the support 1.

[0034] The packaging mechanism includes a top seat 2, which provides mounting support for the drive assembly and spring rod 5. The drive assembly is located on the top of the top seat 2. During the packaging process, the cylinder 3 drives the shrink seat 4 to descend according to the control signal to compress and package the packaging material. After packaging is completed, the cylinder 3 drives the shrink seat 4 to rise and return to the initial position, waiting for the next packaging operation. The drive end of the drive assembly is fixedly connected to the shrink seat 4. When the shrink seat 4 descends, it cooperates with the pressing frame 6 to squeeze and shrink the packaging material, so that the packaging material tightly wraps around the material, achieving sealing and shaping of the packaging. The shrink seat 4 further promotes the shrinkage and adhesion of the packaging material by heating it.

[0035] Spring rods 5 are fixedly connected to the left and right sides inside the top seat 2. When the shrink seat 4 descends, the pressing frame 6 moves downward accordingly, and the spring rods 5 are compressed to store elastic potential energy. When the shrink seat 4 rises, the spring rods 5 release elastic potential energy and push the pressing frame 6 to return to its original position. At the same time, a certain pressure is maintained on the packaging material to ensure the quality and effect of the packaging. The pressing frame 6 is fixedly connected to the left and right sides at the bottom of the spring rods 5. When the shrink seat 4 descends, the pressing frame 6 works in conjunction with the shrink seat 4 to press the packaging material tightly onto the surface of the material, remove air, and make the packaging material conform to the shape of the material. Under the action of the spring rods 5 and the motor 7, the pressing frame 6 presses and shapes the packaging material.

[0036] A motor 7 is fixedly connected to the outer right side of the pressing frame 6. The motor drives the pressure roller 8 and the rotating wheel 9 to rotate, thereby realizing the conveying and processing of packaging materials. The pressure roller 8 is fixedly connected to the drive end of the motor 7. During the packaging process, the pressure roller 8 rotates under the drive of the motor 7, pressing the packaging materials onto the conveyor belt 23 and conveying the packaging materials to the packaging station with the movement of the conveyor belt 23. The rotating wheel 9 is fixedly connected to the drive end of the motor 7. When the motor 7 drives the rotating wheel 9 to rotate, the rotating wheel 9 transmits power to the pressure roller 8 and the pressure roller 11 through the belt 10.

[0037] A belt 10 is connected to the outside of the rotating wheel 9. The belt 10 is driven by the rotating wheel 9 to perform a cyclical motion, transmitting the power of the rotating wheel 9 to the pressure roller 8 and the pressure roller 11. The pressure roller 11 is fixedly connected to the left side of the rotating wheel 9. Through cooperation with the pressure roller 8, the packaging material is compacted and shaped in both directions, further improving the quality and sealing of the packaging. The bottom of the top seat 2 is fixedly connected to the top of the bracket 1.

[0038] The partition sealing and cutting mechanism includes a work box 12, which protects the internal transmission and sealing and cutting components, and provides stable support and guidance for the sealing and cutting knife. A groove 13 is provided on the left side of the inside of the work box 12, providing an independent installation space for the second motor 14. The second motor 14 is fixedly connected inside the groove 13, driving the drive shaft 15 to rotate, thereby driving the second wheel 16, the second belt 17 and the driven shaft 18 to move synchronously, realizing the precise action of the sealing and cutting knife. The drive end of the second motor 14 is fixedly connected to the drive shaft 15, which transmits the rotational motion of the second motor 14 to the second wheel 16 and the lower sealing and cutting knife 19. The bottom side of the outside of the work box 12 is fixedly connected to the top right side of the bracket 1.

[0039] Reference Figure 3 and Figure 4The drive assembly includes a cylinder 3 and a retraction seat 4. The bottom of the cylinder 3 is fixedly connected to the top of the top seat 2, and the top of the retraction seat 4 is fixedly connected to the drive end of the cylinder 3. A rotating wheel 16 is fixedly connected to the outside of the drive shaft 15. Power is transmitted to the driven shaft 18 through a belt 17, thereby realizing the upper sealing cutter 20. A belt 17 is sleeved on the outside of the rotating wheel 16. When the rotating wheel 16 rotates, the belt 17 moves accordingly, driving the driven shaft 18 to rotate synchronously.

[0040] A driven shaft 18 is fixedly connected to the outer side of the rotating wheel 16, which drives the upper sealing cutter 20 to move. When the belt 17 transmits power, the driven shaft 18 rotates synchronously with the rotating wheel 16, thereby driving the upper sealing cutter 20 and the lower sealing cutter 19 to move relative to each other, completing the sealing and cutting operation of the packaging material. The lower sealing cutter 19 is fixedly connected to the outer right side of the drive shaft 15. The lower sealing cutter 19 is responsible for sealing and cutting the bottom of the packaging material during the packaging process. When the drive shaft 15 rotates, the lower sealing cutter 19 rotates accordingly, forming relative movement with the upper sealing cutter 20, cutting the packaging material and performing the sealing operation at the same time.

[0041] An upper sealing cutter 20 is fixedly connected to the outer right side of the driven shaft 18. The upper sealing cutter 20 is responsible for sealing and cutting the top of the packaging material during the packaging process. When the driven shaft 18 rotates, the upper sealing cutter 20 and the lower sealing cutter 19 move synchronously, clamping the packaging material in the middle and performing the sealing and cutting operation. The outer wall of the lower sealing cutter 19 is rotatably connected to the inner wall of the working box 12, and the outer wall of the upper sealing cutter 20 is rotatably connected to the inner wall of the working box 12.

[0042] Reference Figure 1 and Figure 2 The inner wall bottom of the work box 12 is fixedly connected to a telescopic rod 21, which supports and adjusts the position of the partition plate 22. During the packaging process, the telescopic rod 21 can adjust the height of the partition plate 22 according to the size of the packaging material and the sealing position, so as to ensure that the partition plate 22 can accurately divide the packaging material into different packaging units. The bottom left and right sides of the telescopic rod 21 are fixedly connected to the partition plate 22, which can completely close the material channel in a purely physical way during debugging.

[0043] The bottom of the partition plate 22 is slidably connected to the top of the conveyor belt 23. The lower packaging roller 24 is fixedly connected to the outer left side of the bracket 1 for conveying the lower packaging material and transporting the packaging material from the storage position to the packaging area. The lower packaging roller 24 cooperates with the upper packaging roller 25 to wrap the product. The upper packaging roller 25 is fixedly connected to the outer left side of the top seat 2 for conveying the upper packaging material. It cooperates with the lower packaging roller 24 to cover the product with the packaging material and to package the product.

[0044] An auxiliary roller 26 is fixedly connected to the top of the support 1 for guiding and supporting the packaging material. The bottom of the pressing frame 6 is slidably connected to the top of the conveyor belt 23. The bottom of the first pressing roller 8 is rotatably connected to the top of the conveyor belt 23, and the bottom of the second pressing roller 11 is rotatably connected to the top of the conveyor belt 23.

[0045] Working principle: During operation, the material to be packaged is conveyed from the input end of the packaging machine to the packaging station. During the packaging process, the cylinder 3 drives the shrink seat 4 to descend according to the control signal. When the shrink seat 4 descends, it cooperates with the pressing frame 6, and the pressing frame 6 moves downward accordingly. The spring rod 5 is compressed, and the pressure roller 8 rotates under the drive of the motor 7, pressing the packaging material onto the conveyor belt 23. With the movement of the conveyor belt 23, the packaging material is conveyed to the packaging station. At the same time, the drive end of the motor 7 drives the rotating wheel 9 to rotate. The rotating wheel 9 transmits power to the pressure roller 11 through the belt 10. The pressure roller 8 and the pressure roller 11 cooperate to compress the packaging material in both directions. During the descent of the shrink seat 4, it cooperates with the pressing frame 6 to squeeze and shrink the packaging material. At the same time, the shrink seat 4 further promotes the shrinkage and adhesion of the packaging material through heating, so that the packaging material tightly wraps around the material, realizing the sealing and shaping of the packaging.

[0046] When the packaging material moves with the conveyor belt 23 to below the work box 12, the motor 14 starts, driving the drive shaft 15 to rotate. This drives the wheel 16 and the lower sealing cutter 19, which are fixed on the drive shaft 15, to rotate synchronously. The wheel 16 drives the driven shaft 18 to rotate via the belt 17, causing the upper sealing cutter 20 and the lower sealing cutter 19, which are fixed on the driven shaft 18, to move relative to each other. At this time, the telescopic rod 21 adjusts the height of the partition plate 22 according to the size of the packaging material and the sealing position. The partition plate 22 divides the packaging material into different packaging units. When the upper sealing cutter 20 and the lower sealing cutter 19 rotate to the closed position, they cut and seal the packaging material, completing the sealing of a single packaging unit. Then, the partition plate 22 rises, and the conveyor belt 23 continues to transport the packaging material, entering the next sealing cycle.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
