Description

Technical Field

[0001] This utility model relates to the field of triangular bag packaging machine technology, and more specifically, to an integrated nylon triangular bag inner and outer bag packaging machine. Background Technology

[0002] The triangular bag inner and outer bag packaging machine is a type of machinery specifically designed to package products into a triangular shape and simultaneously complete the inner and outer bag packaging processes. It automatically loads materials into triangular bags, first performing inner bag packaging and then covering them with an outer bag, thereby improving the sealing, aesthetics, and protection of the product packaging. During operation, the inner bag film is released from the unwinding device, passes through the bag forming component to form a triangular shape, and simultaneously, the material is conveyed into the triangular inner bag according to the amount set by the metering device via the conveying system. Then, the inner bag sealing device seals the inner bag opening. Next, the outer bag film is also released from the unwinding device and placed over the already packaged triangular bag. After another bag forming and sealing operation, the inner and outer bag packaging of the triangular bag is finally completed. However, existing triangular bag inner and outer bag packaging machines are inconvenient for positioning the entire roll of nylon packaging bags during use, and the nylon packaging bags are prone to excessive unwinding during packaging, affecting the quality of the triangular bags.

[0003] To address the aforementioned issues, particularly the inconvenience of positioning the entire roll of nylon packaging bags in existing triangular bag packaging machines, which can lead to excessive unwinding and affect the quality of the triangular bags, extensive research revealed a triangular bag packaging machine with patent publication number X. This device, belonging to the field of triangular bag packaging machine technology, uses a positioning mechanism to position the packaging bag roll, preventing excessive unwinding and offering greater ease of use.

[0004] However, the aforementioned triangular packaging machine for inner and outer bags still has some problems. For example, after installing the positioning mechanism, the central mounting shaft and packaging bag roll material become inconvenient to replace, resulting in a decrease in the packaging efficiency of subsequent packaging machines. To address these problems, this utility model proposes an integrated nylon triangular inner and outer bag packaging machine. Utility Model Content

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide an integrated nylon triangular bag inner and outer bag packaging machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated nylon triangular bag inner and outer bag packaging machine, comprising: a base, on which two support plates are provided opposite each other at the top; a rotating column is rotatably connected to the two support plates; a film roller is detachably connected to the rotating column; an insert block is fixedly connected to both sides of the film roller; an insert groove is embedded in the rotating column for the insert block to be inserted into; a limiting hole is provided through the insert block; and a limiting component is provided on the rotating column to limit the movement of the limiting hole, the limiting component comprising:

[0007] A double-ended screw, which is rotatably mounted on the rotating column;

[0008] Two L-shaped rods, the first end of which is sleeved and threaded to both ends of the double-ended screw, and the second ends of the two L-shaped rods are movably disposed on the rotating column, and fixedly connected to the limiting hole with a limiting rod, which is configured to limit the limiting hole.

[0012] A further preferred embodiment: a pressing mechanism is provided between the support plate and the guide roller, the pressing mechanism comprising:

[0013] Two connecting blocks are rotatably connected to the two guide rollers respectively. A slider is fixedly connected to each of the two connecting blocks. The fixed plate is provided with a sliding groove for the slider to slide.

[0017] Beneficial effects:

[0018] 1. By setting a limiting component and limiting holes, the film roller's insert block is embedded into the insert groove of the rotating column, and then the limiting component limits the limiting holes, thereby enabling quick assembly and disassembly of the film roller. The reliable fixation of the film roller by the limiting component ensures that the film roller maintains a stable rotation state during rotation, avoiding uneven film feeding, wrinkles, or interruptions caused by problems such as film roller shaking, offset, or accidental detachment. This provides a stable, continuous, and high-quality film supply for subsequent packaging processes such as bag making, material filling, and sealing, helping to improve the overall working stability of the packaging machine and the consistency of packaging quality.

[0019] 2. By incorporating guiding and squeezing mechanisms, the stability and reliability of the packaging process are improved, reducing waste of packaging materials and degradation of packaging quality caused by film tension issues, thereby increasing production efficiency and product packaging quality;

[0020] 3. By incorporating a stop assembly, the lateral shift of the film during transport can be reduced, further ensuring the accuracy of the film's position when entering subsequent packaging processes. This helps improve the precision of processes such as bag making and material filling, thereby enhancing the overall packaging quality and product packaging consistency of the packaging machine.

[0029] The following will refer to the appendix in the embodiments of this utility model. Figures 1-7 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0030] Please see Figure 1-7 In this embodiment of the utility model, the integrated nylon triangular bag inner and outer bag packaging machine includes a base 1, on which two support plates 2 are provided opposite to each other on the top. A rotating column 3 is rotatably connected to the two support plates 2. A film roller 4 is detachably connected to the rotating column 3. An embedded block 6 is fixedly connected to both sides of the film roller 4. An embedded groove 5 is embedded in the rotating column 3 for the embedded block 6 to be embedded in. A limiting hole 12 is provided through the embedded block 6. A limiting component 9 is provided on the rotating column 3 to limit the limiting hole 12. The limiting component 9 includes a double-headed screw 91, which is rotatably set on the rotating column 3. Two L-shaped rods 92, the first end of which is sleeved and threaded to both ends of the double-headed screw 91. The second ends of the two L-shaped rods 92 are movably set on the rotating column 3 and fixedly connected to the limiting hole 12 with a limiting rod 93. The limiting rod 93 is configured to limit the limiting hole 12.

[0031] Specifically, when installing the film roller 4, first align the insert blocks 6 on both sides of the film roller 4 with the insert grooves 5 on the rotating column 3, and then slide the insert blocks 6 into the insert grooves 5 so that the film roller 4 can be initially positioned on the rotating column 3. Next, rotate the double-ended screw 91. Since the double-ended screw 91 is threadedly connected to the first end of the two L-shaped rods 92, and the threads at both ends of the double-ended screw 91 are in opposite directions, when the double-ended screw 91 rotates, the two L-shaped rods 92 will move relative to each other or towards each other along the axial direction of the double-ended screw 91. The second end of the L-shaped rod 92 has a corresponding movable guide structure on the rotating column 3 to ensure that it can move horizontally stably. As the L-shaped rod 92 moves, the limiting rod 93 at its end will gradually approach the limiting hole 12 on the insert block 6 and finally insert into the limiting hole 12, thereby firmly fixing the film roller 4 on the rotating column 3 and preventing it from axial displacement or rotation during operation. When the film roller 4 needs to be disassembled, the double-headed screw 91 is rotated in the reverse direction to disengage the limiting rod 93 from the limiting hole 12, and the film roller 4 can be removed from the rotating column 3. This detachable connection design makes the replacement of the film roller 4 extremely convenient. The reliable fixation of the film roller 4 by the limiting component 9 ensures that the film roller 4 maintains a stable rotation state during rotation, avoiding uneven film feeding, wrinkles or interruptions caused by the shaking, deviation or accidental detachment of the film roller 4. This provides a stable, continuous and high-quality film supply for subsequent packaging processes such as bag making, filling materials and sealing, which helps to improve the working stability of the entire packaging machine and the consistency of packaging quality.

[0032] It should be noted that this embodiment aims to improve the replacement of the film roller 4 in the integrated nylon triangular bag inner and outer bag packaging machine. The overall structure and operation mode of the integrated nylon triangular bag inner and outer bag packaging machine can be referred to the published documents with patent announcement numbers CN204871676U and CN214268153U, or the prior art, which will not be described here. Secondly, both the embedding block 6 and the embedding groove 5 are square structures. In order to make the embedding block 6 accurately embedded in the groove 5, the rotating column 3 can be positioned by a positioning mechanism before the two are installed. For example, a hole can be opened on the rotating column 3, and the hole can be positioned by using a pin or screw. The installation position and structure of the two are the prior art.

[0033] In this embodiment of the utility model, such as Figure 7 As shown, a movable plate 13 is fitted onto the L-shaped rod 92, and a movable groove 15 is provided inside the rotating column 3 for the movable plate 13 to move. A first spring 14 is provided inside the movable groove 15. The first spring 14 is fitted onto the L-shaped rod 92. Specifically, when the double-headed screw 91 is rotated to adjust the position of the L-shaped rod 92, the movable plate 13 will move with the L-shaped rod 92 in the movable groove 15, and the first spring 14 will be compressed or stretched. The presence of the first spring 14 provides a certain elastic buffer force for the L-shaped rod 92, which facilitates the reset of the L-shaped rod 92.

[0034] In this embodiment of the utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, a handle 10 is fixedly connected to the double-ended screw 91.

[0035] In this embodiment of the utility model, such as Figure 1 , Figure 2 and Figure 5 As shown, it also includes a guiding mechanism 7, which is fixedly mounted on the base 1 relative to the film roller 4. The guiding mechanism 7 includes two fixed plates 72 and two guiding rollers 71. The two fixed plates 72 are fixedly connected to the base 1, and the two guiding rollers 71 are rotatably disposed between the two fixed plates 72. A gap is defined between the two guiding rollers 71 for the film to pass through. Specifically, after the film is drawn out from the film roller 4, it passes through the gap defined by the two guiding rollers 71 between the two fixed plates 72. The guiding rollers 71 rotate under the pull of the film and guide the film smoothly to the subsequent packaging process through the friction with the film. This ensures that the film maintains the correct direction and appropriate tension during the transportation process, avoids problems such as wrinkles, deviations or loosening of the film, and ensures the stability and accuracy of film transportation.

[0036] In this embodiment of the utility model, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a pressing mechanism 8 is provided between the support plate 2 and the guide roller 71. The pressing mechanism 8 includes two connecting blocks 81, which are rotatably connected to the two guide rollers 71 respectively. A slider 82 is fixedly connected to each of the two connecting blocks 81. The fixed plate 72 is provided with a groove 84 for the slider 82 to slide. A second spring 83 is located in the groove 84, and both ends of the second spring 83 are fixedly connected to the two sliders 82 respectively. The slider 82 has a T-shaped structure. Specifically, when the tension of the film changes during the conveying process, such as when the film is suddenly stretched or relaxed, the guide roller 71 will move in the groove 84 under the drive of the connecting blocks 81 and the slider 82. The spring 83 is compressed or stretched according to the movement of the guide roller 71, thereby adjusting the position of the guide roller 71 and changing the gap between the two guide rollers 71 to adapt to changes in film tension. This applies appropriate pressure to the film, ensuring that the film always maintains suitable tension, thus achieving automatic adjustment of film tension. It can adjust the tension in real time according to the actual situation of the film, avoiding problems such as film breakage due to excessive tension or film loosening and wrinkling due to insufficient tension. This helps to improve the stability and reliability of the packaging process, reduce waste of packaging materials and decline in packaging quality caused by film tension problems, and improve production efficiency and product packaging quality.

[0037] In this embodiment of the utility model, such as Figure 5 and Figure 6 As shown, a stop assembly 11 is provided between the two connecting blocks 81. The stop assembly 11 is located adjacent to the guide roller 71. The stop assembly 11 includes a fixed block 111, a telescopic block 112, and a telescopic groove 113. The fixed block 111 and the telescopic block 112 are fixedly connected to the two connecting blocks 81 respectively. The fixed block 111 is provided with a telescopic groove 113 through it. The telescopic block 112 is slidably disposed in the telescopic groove 113. Specifically, when the film is conveyed between the guide rollers 71, if the film is laterally offset, the telescopic block 112 will slide accordingly in the telescopic groove 113, which plays a certain role in blocking and correcting the lateral offset of the film, so that the film is conveyed in the center position between the two guide rollers 71 as much as possible. This helps to improve the accuracy of film conveying, reduce the lateral offset of the film during the conveying process, and further ensure the positional accuracy of the film when it enters the subsequent packaging process. This is conducive to improving the accuracy of bag making, filling materials and other processes, thereby improving the packaging quality and product packaging consistency of the entire packaging machine.

[0038] Working principle: When installing the film roller 4, first align the insert blocks 6 on both sides of the film roller 4 with the insert grooves 5 on the rotating column 3, and then slide the insert blocks 6 into the insert grooves 5 to initially position the film roller 4 on the rotating column 3. Next, rotate the double-ended screw 91 by the handle 10. Since the double-ended screw 91 is threaded to the first end of the two L-shaped rods 92 and the threads at both ends of the double-ended screw 91 are opposite, when the double-ended screw 91 rotates, the two L-shaped rods 92 will move relative to each other or towards each other along the axial direction of the double-ended screw 91. The second end of the L-shaped rod 92 has a corresponding movable guide structure on the rotating column 3 to ensure that it can move horizontally stably. As the L-shaped rod 92 moves, the limiting rod 93 at its end will gradually approach the limiting hole 12 on the insert block 6 and finally insert into the limiting hole 12, thereby firmly fixing the film roller 4 on the rotating column 3 and preventing it from axial displacement or rotation during operation. When the film roller 4 needs to be disassembled, the double-headed screw 91 is rotated in the reverse direction to disengage the limiting rod 93 from the limiting hole 12, and the film roller 4 can be removed from the rotating column 3. This detachable connection design makes the replacement of the film roller 4 extremely convenient. The reliable fixation of the film roller 4 by the limiting component 9 ensures that the film roller 4 maintains a stable rotation state during rotation, avoiding uneven film feeding, wrinkles or interruptions caused by the shaking, deviation or accidental detachment of the film roller 4. This provides a stable, continuous and high-quality film supply for subsequent packaging processes such as bag making, filling materials and sealing, which helps to improve the working stability of the entire packaging machine and the consistency of packaging quality.
