[0001] This utility model relates to the field of roller brush separation devices, specifically to a roller brush separation device for separating packaging bags. Background Technology

[0002] As a traditional meat product, the packaging process after pork jerky processing directly affects product quality and shelf life. Currently, pork jerky is mainly packaged in vacuum bags, but in subsequent sorting and boxing processes, it is often necessary to separate the stacked bags one by one. In traditional production methods, this separation process relies on manual operation, which is not only inefficient but also prone to causing inconsistent product quality.

[0003] Although pork jerky processing has gradually become mechanized in recent years, the current separation equipment on the market generally has the problem of incomplete separation in the key process of separating packaging bags. During automated sorting, packaging bags are easily damaged, and even the contents may be damaged, making it difficult to meet the dual requirements of food hygiene standards and production efficiency.

The second flexible roller brush is a rotatable structure, and its surface is covered with silicone bristles. The second driving member is drivenly connected to the second flexible roller brush.

[0009] In some embodiments, the flow guiding module includes a third housing and a flow guiding plate. One end of the third housing is fixedly connected to the first housing. The flow guiding plate is inclined and has an antistatic coating on its outer surface.

[0010] In some embodiments, a vibration generator is disposed below the flow guiding module.

[0011] In some embodiments, the vacuum suction cup is made of food-grade silicone, and its adsorption end face is provided with annular ribs.

[0032] Please see Figures 1 to 5 This embodiment provides a roller brush separation device for separating packaging bags, including a roller brush separation mechanism 1, a negative pressure adsorption module 2, and a flow guiding module 3. The roller brush separation mechanism 1 includes a first outer shell 11, an upper roller brush assembly 12, and a lower roller brush assembly 13. The outer shell covers the outside of the upper roller brush assembly 12 and the lower roller brush assembly 13. The upper roller brush assembly 12 and the lower roller brush assembly 13 are arranged in parallel, and a separation channel for the packaging bag to pass through is formed between the upper roller brush assembly 12 and the lower roller brush assembly 13. The negative pressure adsorption module 2 is disposed at the front end of the roller brush separation mechanism 1 and includes a second outer shell 21, a suction cup bracket 22, multiple sets of vacuum suction cups 23, a telescopic component 24, and a transverse moving guide rail 25. Multiple sets of vacuum suction cups 23 are disposed at the bottom of the suction cup bracket 22, and the suction cup bracket 22 is connected to the transverse moving guide rail 25 through the telescopic component 24. The flow guiding module 3 is disposed at one end of the roller brush separation mechanism 1.

[0033] In this embodiment, the first outer shell 11 is preferably a metal frame structure to protect the internal roller brush assembly and maintain structural stability. A cushioning pad can be provided on its inner side to prevent scratches on the packaging bags. Both the upper roller brush assembly 12 and the lower roller brush assembly 13 include a metal shaft core and an elastic rubber layer covering the surface. Differential rotation generates the shear force required for separation, and the spacing of the separation channels formed by the two is adjustable to accommodate packaging bags of different thicknesses. The second outer shell 21 is made of lightweight aluminum alloy and integrates a vacuum pipeline system to provide stable negative pressure for the vacuum suction cups 23. The suction cup support 22 is a deformable engineering plastic part, and the vacuum suction cups 23 arranged in an array at its bottom are made of silicone, achieving selective adsorption through independent air path control. The telescopic assembly 24 includes an electric push rod and a guide rail for vertical position compensation; the lateral movement guide rail 25 is driven by a linear motor, enabling the suction cup assembly to scan the stack of packaging bags to be separated laterally. The flow guiding module 3 includes an inclined polyurethane guide plate with micro-textured surfaces to reduce frictional resistance and to regulate the movement trajectory of the separated packaging bags.

[0034] The working principle of this device can be understood as follows: The negative pressure adsorption module 2 first adjusts the horizontal position of the vacuum suction cup 23 via the lateral moving guide rail 25, and the telescopic component 24 presses down to make the suction cup contact the surface of the packaging bag to form adsorption. Subsequently, the adsorbed packaging bag is pulled to the entrance of the separation channel, where the upper roller brush component 12 and the lower roller brush component 13 rotate at a set speed difference, using the difference in surface friction to separate the stacked packaging bags layer by layer. The separated single-layer packaging bags are then discharged through the inclined guide plate of the flow guiding module 3, completing the sorting process. This device significantly improves its adaptability to packaging bags of different materials and thicknesses through the synergistic effect of the flexible gripping of the negative pressure adsorption module 2 and the differential speed separation of the roller brush component.

[0035] This embodiment utilizes the multi-degree-of-freedom adjustment capability of the negative pressure adsorption module 2 to enable the vacuum suction cup 23 to precisely adapt to the surface undulations of the packaging bag stack, avoiding the adsorption failure caused by positional deviation of traditional fixed suction cups. The roller brush separation mechanism 1 adopts an adjustable-spacing parallel double roller brush design, achieving gentle separation through the shearing force generated by differential rotation, preventing damage to thin packaging bags and effectively solving the adhesion problem. The directional guiding structure of the flow guiding module 3 ensures the orderly transport of packaging bags after separation, avoiding deflection caused by airflow interference. The entire device, through modular collaborative operation, improves the separation success rate while ensuring the integrity of the packaging bags, making it particularly suitable for the automated separation of pork jerky packaging bags.

[0036] In some embodiments, the upper roller brush assembly 12 includes a first flexible roller brush 121 and a first drive member 122. The first flexible roller brush 121 is a rotatable structure, and the surface of the first flexible roller brush 121 is covered with segmented silicone protrusions. The first drive member 122 is connected to the first flexible roller brush 121 in a transmission manner.

[0037] In this embodiment, a first flexible roller brush 121 with segmented silicone protrusions is used. When rotated by the drive component, its flexible contact characteristics can adapt to the surfaces of packaging bags of different thicknesses and materials. The segmented protrusion structure can enhance local friction to improve the separation effect, and can also avoid damage to the surface of the packaging bag through elastic deformation. When working in conjunction with the lower roller brush assembly 13, the special surface texture of the first flexible roller brush 121 and the rotation action work together to generate a progressive separation force, so that the stacked packaging bags can be peeled off layer by layer when passing through the separation channel. This solves the problem that traditional rigid roller brushes are prone to causing packaging bag deformation or breakage, and effectively prevents incomplete separation caused by insufficient friction. Overall, it achieves a gentler and more reliable separation effect for various types of packaging bags, and is particularly suitable for the automated separation of pork jerky packaging bags.

[0038] In some embodiments, multiple sets of silicone protrusions are provided and are staggered on the outer surface of the first flexible roller brush 121, and the silicone protrusions have a hemispherical structure.

[0039] In this embodiment, multiple sets of staggered hemispherical silicone protrusions effectively disperse the contact stress between the roller brush and the packaging bag through curved surface contact, avoiding bag indentations or damage caused by stress concentration at the edges of traditional strip-shaped protrusions. The hemispherical structure makes it easier to peel off attached debris during high-speed rotation, and the self-cleaning gaps formed by the staggered arrangement can significantly reduce the risk of material residue. Furthermore, the flexible silicone material and spherical geometry work together to ensure separation efficiency while also protecting the surfaces of fragile packaging such as aluminum foil bags, and its seamless shape further meets the hygiene control standards of food-grade production lines.

[0040] In some embodiments, the lower roller brush assembly 13 includes a second flexible roller brush 131 and a second drive member 132. The second flexible roller brush 131 is a rotatable structure, and the surface of the second flexible roller brush 131 is covered with silicone bristles. The second drive member 132 is connected to the second flexible roller brush 131 in a transmission manner.

[0041] In this embodiment, a second flexible roller brush 131 with silicone bristles is used in the lower roller brush assembly 13 to form a complementary separation structure with the first flexible roller brush 121 with silicone protrusions. When the packaging bag passes through the separation channel, the hemispherical protrusions of the upper roller brush generate local point contact pressure, while the dense bristles of the lower roller brush form surface contact support. This point-to-surface separation method ensures sufficient friction to effectively separate the stacked packaging bags, while avoiding surface scratches through flexible contact. The second drive unit 132 independently controls the rotation speed of the second flexible roller brush 131, enabling it to form a precise speed difference with the first flexible roller brush 121, resulting in an optimized shearing separation effect. Especially for packaging bags with smooth surfaces or ultra-thin materials, the elastic deformation characteristics of the silicone bristles can adaptively conform to the bag surface, preventing slippage or leakage during separation. Overall, this improves the device's adaptability to separating packaging bags with different characteristics and its operational reliability.

[0042] In some embodiments, the flow guiding module 3 includes a third housing 31 and a flow guiding plate 32. One end of the third housing 31 is fixedly connected to the first housing 11. The flow guiding plate 32 is inclined and has an antistatic coating on its outer surface.

[0043] In this embodiment, by employing an inclined guide plate 32 with an antistatic coating, after the separated packaging bags are output by the roller brush assembly, the inclined structure of the guide plate 32 can naturally guide the packaging bags to slide along a predetermined trajectory, avoiding stacking chaos caused by free fall. At the same time, the antistatic coating effectively eliminates the electrostatic adsorption phenomenon caused by friction during the transportation of the packaging bags, preventing the thin bags from sticking to the surface of the guide plate 32 or adsorbing each other, ensuring that the sorted packaging bags can smoothly enter the next process. The fixed connection between the third outer shell 31 and the first outer shell 11 enhances the overall structural stability, enabling the guide module 3 to withstand mechanical vibration during continuous operation and maintain long-term guiding accuracy.

[0044] This embodiment not only improves the conveying efficiency after the packaging bags are separated, but also ensures the integrity and sorting reliability of the thin packaging bags through anti-static treatment, making it particularly suitable for high-speed automated production lines for pork jerky production.

[0045] In some embodiments, a vibration generator 4 is disposed below the flow guiding module 3.

[0046] In this embodiment, by adding a vibration generator 4 below the flow guide module 3, the slight vibration generated by the vibration generator 4 when the packaging bag slides down the inclined flow guide plate 32 can effectively eliminate the adsorption force between the packaging bag and the flow guide plate 32, preventing the bag from being stuck due to static electricity or surface tension, and ensuring that it slides smoothly into the collection device. At the same time, the vibration can make the stacked packaging bags naturally loosely arranged, avoiding accumulation and blockage, significantly improving sorting efficiency and the continuity of system operation. This embodiment is particularly suitable for high-speed sorting scenarios, optimizing material flow performance while ensuring gentle handling.

[0047] In some embodiments, the vacuum suction cup 23 is made of food-grade silicone, and its adsorption end face is provided with annular ribs 231.

[0048] In this embodiment, the vacuum suction cup 23 made of food-grade silicone meets food packaging hygiene standards. Its annular ribs 231 design enhances adsorption stability through multi-stage sealing and adapts to the minute unevenness of the aluminum foil bag surface to prevent air leakage and failure. The gaps between the annular ribs 231 form airflow channels, reducing surface residue adhesion when releasing the packaging bag and simultaneously reducing the frequency of cleaning and maintenance. Through the synergistic effect of soft silicone and annular ribs 231, both adsorption indentation is prevented and the reliability of continuous operation on high-speed production lines is ensured, comprehensively solving the problems of adsorption damage and hygiene hazards of traditional pneumatic devices.

[0049] By using the above technical solutions, this utility model differs from the prior art and has the following beneficial effects: Through the multi-degree-of-freedom adjustment design of the negative pressure adsorption module 2, the vacuum suction cup 23 can accurately adapt to the surface undulations of the packaging bag stack, avoiding the adsorption failure problem caused by positional deviation of traditional fixed suction cups. The roller brush separation mechanism 1 adopts an adjustable spacing parallel double roller brush design. The segmented silicone protrusions of the upper roller brush assembly 12 and the silicone bristles of the lower roller brush assembly 13 form a complementary structure. The shearing force generated by differential rotation achieves gentle separation, which not only prevents damage to thin packaging bags but also effectively solves the adhesion problem. Among them, the hemispherical silicone protrusions of the upper roller brush, through staggered distribution and curved surface contact characteristics, ensure separation efficiency while protecting the surface integrity of the packaging bag.

[0050] The inclined guide plate 32 of the flow guiding module 3, combined with the antistatic coating and vibration generator 4, effectively solves the problems of electrostatic adsorption and accumulation during the conveying of packaging bags. The antistatic coating eliminates electrostatic interference caused by friction, while the vibration generator 4 further ensures that the packaging bags slide smoothly, avoiding stagnation and jamming. This design significantly improves sorting efficiency and system operation continuity, and is particularly suitable for high-speed automated production lines.

[0051] The above technical solution, through the coordinated operation of various modules, enables the entire device to possess excellent adaptability and reliability: the flexible gripping of the negative pressure adsorption module 2, the differential separation of the roller brush assembly, and the orderly conveying of the flow guiding module 3 work together to improve the separation success rate while ensuring the integrity of the packaging bag. The design of the food-grade silicone vacuum suction cup 23 and the annular rib 231 further meets hygiene standards, ensuring the applicability of the device in high-standard scenarios such as food packaging. In summary, this utility model achieves efficient, gentle, and reliable separation of various packaging bags, and is particularly suitable for food packaging fields such as pork jerky. Its gentle separation and anti-static design effectively maintain the integrity of thin and fragile packaging, ensuring that products are undamaged and uncontaminated during automated sorting, meeting food hygiene standards.

[0052] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this utility model, this should not limit the scope of patent protection of this utility model.
