Description

Technical Field

[0001] This utility model relates to the field of product packaging technology, and in particular to a three-dimensional packaging machine for multi-layer packaging. Background Technology

[0002] Product packaging aims to protect products from external environmental damage, such as moisture, dust, and impacts, ensuring their safety during transportation and storage. Simultaneously, packaging extends the product's shelf life and prevents spoilage and contamination. Furthermore, packaging serves an aesthetic purpose, attracting consumers through attractive designs and enhancing the product's market competitiveness and brand image. Overall, product packaging not only protects the product but also increases its added value and promotes sales.

[0003] Three-dimensional packaging machines, also known as tobacco packaging machines, are mainly used for three-dimensional packaging of tobacco products or other similar products. This equipment uses an automated process to encapsulate products in three dimensions using packaging materials (such as film and paper). Its working principle involves stretching and shaping the packaging material through mechanical devices, then encapsulating the product within, ensuring that the product is not damaged during transportation and storage. It is widely used in the food, electronics, and pharmaceutical industries.

[0004] However, existing 3D packaging machines have some shortcomings in terms of hopper adjustment and film replacement. Traditional hopper designs typically require changing to different hopper sizes to accommodate different materials, which is complex and time-consuming. The fixed position and standardized design of the hopper limit its flexibility, resulting in significant manual and equipment adjustments when switching between different materials. Furthermore, film roll replacement usually requires lengthy downtime for disassembly, which not only increases downtime but also raises maintenance difficulty and labor costs.

[0005] To address the above problems, a three-dimensional packaging machine for multi-layer packaging is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a three-dimensional packaging machine for multi-layer packaging, aiming to solve the problems of cumbersome hopper replacement, inflexible material feeding adjustment, and inconvenient film replacement in existing three-dimensional packaging machines.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a three-dimensional packaging machine for multi-layer packaging, comprising an operating machine, wherein a hopper, a film-cutting box, a hot press box and a drive box are sequentially arranged on the top of the operating machine, and adjustment components are arranged on both sides of the hopper, the adjustment components being used to control the size of the items being fed, and a transparent film roll is mounted on the drive box, and an installation component is arranged on the outside of the transparent film roll, the installation component being used to quickly disassemble and fix the transparent film roll;

[0008] The adjustment assembly includes two support plates and a limiting block, and a bidirectional threaded rod is provided between the two support plates. One end of the bidirectional threaded rod is fixedly connected to a throttle, and a sliding groove is provided inside the limiting block.

[0009] As a further description of the above technical solution:

[0010] The bottom of the two support plates is fixedly connected to the top sides of the manipulator, and both are located on one side of the hopper, while the limiting block is located on the other side of the hopper.

[0011] As a further description of the above technical solution:

[0012] The hopper has curved sections on both sides of its top, two control blocks are installed on the side of the hopper near the support plate, and two sliders are installed on the other side of the hopper.

[0013] As a further description of the above technical solution:

[0014] The bidirectional threaded rod is rotatably connected inside the two control blocks, and the two sliders are slidably connected inside the first slide groove.

[0015] As a further description of the above technical solution:

[0016] The manipulator is equipped with a conveyor belt inside, and several abutments are fixedly connected to the top of the conveyor belt.

[0017] As a further description of the above technical solution:

[0018] The hopper is slidably connected to the top of the manipulator, and multiple drive rollers are installed on the front side of the drive box, with the transparent film roll sleeved on the outside of one of the drive rollers.

[0019] As a further description of the above technical solution:

[0020] The mounting assembly includes an outer abutment ring and an inner abutment ring, and multiple connecting blocks are installed between the two. The outer side of the drive roller is provided with a second groove corresponding to the number of connecting blocks, and the inside of the second groove is provided with a slot.

[0021] As a further description of the above technical solution:

[0022] The inner abutment ring is slidably connected to the outside of the drive roller, and the connecting block is slidably connected to the inside of the second groove, with multiple connecting blocks snapped into the inside of the groove.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this invention, an adjustable component is installed on the outside of the hopper. By rotating the handle on the adjusting component, the movement of the bidirectional threaded rod can be controlled, thereby adjusting the control block and slider on the outside of the hopper. This allows the two hoppers to move synchronously, thus changing the amount of material discharged between them. When processing different materials, users do not need to change the hoppers; they only need to adjust the control component to achieve precise material feeding. This not only improves the flexibility of the equipment but also greatly saves the time and cost of changing hoppers, thereby increasing production efficiency.

[0025] 2. In this invention, after the transparent film roll is used up, the user only needs to rotate the outer abutment ring and adjust its internal connecting block to move it in the sliding groove and slot inside the drive roller, thereby easily removing the used film roll and quickly installing a new film roll. This simplifies the film replacement process, improves the operating efficiency of the production line, and ensures the continuity and stability of the production process.

[0031] 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.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a three-dimensional packaging machine for multi-layer packaging, including an operating machine 1. The operating machine 1 has a conveyor belt 11 inside, which transports products from one location to the next packaging processing area. Several abutments 12 are fixedly connected to the top of the conveyor belt 11, which can guide the items to be packaged, fed into the hopper 2, one by one into the next process. The top of the operating machine 1 is sequentially arranged with a hopper 2, a film-cutting box 4, a thermoforming box 5, and a drive box 6, forming an efficient packaging process. Both sides of the top of the hopper 2 are provided with curved sections 21, which help guide the material to slide down to the packaging area. Two control blocks 22 are installed on the side of the hopper 2 near the support plate 31, and two sliders 23 are installed on the other side of the hopper 2. The hopper 2 is slidably connected to the top of the operating machine 1, enabling rapid material changing. Adjustment components 3 are provided on both sides of the hopper 2. These components can control the size of the hopper 2 by adjusting the bidirectional threaded rod 32, thereby precisely controlling the size of the items being fed and adapting to the packaging needs of different materials, avoiding the hassle of changing the hopper 2. Multiple drive rollers 61 are installed on the front side of the drive box 6. These drive rollers 61 are responsible for driving the transparent film roll 7 for automatic feeding. The transparent film roll 7 is fitted onto the outside of one of the drive rollers 61 and is adjusted by the automatic control system. Furthermore, an installation component 8 is provided on the outside of the transparent film roll 7. This installation component 8 adopts a quick-disassembly and fixing design, allowing for convenient and quick replacement when the transparent film roll 7 is used up, reducing downtime and improving production efficiency.

[0033] Reference Figure 1 - Figure 2 The adjustment assembly 3 includes two support plates 31 and a limiting block 34. A bidirectional threaded rod 32 is provided between the two support plates 31. The bidirectional threaded rod 32 is rotatably connected to the inside of two control blocks 22, allowing the control blocks 22 to drive the two hoppers 2 to move in opposite directions. One end of the bidirectional threaded rod 32 is fixedly connected to a handle 33. By rotating the handle 33, the movement of the bidirectional threaded rod 32 can be easily adjusted, thereby changing the distance between the hoppers 2 and adjusting the amount of material discharged. This allows the hoppers 2 to quickly and accurately adjust the discharge amount according to the needs of different materials without having to replace the hoppers 2, greatly improving the flexibility and adaptability of the equipment. The limiting block 34 has a groove 35 inside, and two sliders 23 are slidably connected inside the groove 35, ensuring the smooth movement of the hoppers 2 and enabling precise control of the sliding position of the hoppers 2.

[0034] Reference Figure 3The mounting assembly 8 includes an outer abutment ring 81 and an inner abutment ring 82, with multiple connecting blocks 83 installed between them. The inner abutment ring 82 is slidably connected to the outside of the drive roller 61, ensuring a stable connection during the movement of the drive roller 61 and providing the necessary abutment pressure to maintain the tight wrapping of the film roll. The outer side of the drive roller 61 has grooves 84 matching the number of connecting blocks 83. These grooves 84 guide the connecting blocks 83 to slide internally, ensuring smooth movement. The grooves 84 have slots 85 inside. With this structure, when a connecting block 83 slides to the end of the groove 84, rotating the outer abutment ring 81 engages the connecting block 83 with the slot 85, ensuring a secure connection between the connecting block 83 and the drive roller 61.

[0035] Working Principle: First, the manipulator 1 conveys the items to be packaged to the hopper 2 via the conveyor belt 11. Multiple abutments 12 fixedly connected to the top of the conveyor belt 11 ensure that the items smoothly enter the hopper 2 and proceed to the next packaging stage. The adjustment assembly 3 consists of a bidirectional threaded rod 32 and a handle 33. The user can adjust the rotation of the bidirectional threaded rod 32 by rotating the handle 33, thereby driving the movement of the control block 22 and the slider 23, adjusting the distance between the hoppers 2, and precisely controlling the size of the materials to be packaged. This design avoids the hassle of changing hoppers 2 and improves the flexibility and adaptability of operation. Subsequently, the material is sealed in the heat-sealing box 5. Before this, the film-cutting box 4 cuts the transparent film roll 7. The film is stretched and conveyed to the packaging area by the drive roller 61 in the drive box 6. The transparent film roll 7 is securely connected to the drive roller 61 by the mounting assembly 8. The mounting assembly 8 uses multiple connecting blocks 83 between the outer abutment ring 81 and the inner abutment ring 82 to achieve quick disassembly and fixation, ensuring the tight wrapping of the transparent film roll 7 and facilitating quick replacement. When the transparent film roll 7 is used up, rotating the outer abutment ring 81 can unlock the engagement between the connecting block 83 and the slot 85, enabling quick replacement of the transparent film roll 7, reducing downtime, and ensuring efficient packaging.

[0036] 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.
