Description

Technical Field

[0001] This utility model belongs to the field of modified plastic granule processing technology, and in particular relates to a ton bag packaging device for modified plastic granules. Background Technology

[0002] Modified plastic granules are plastic granules obtained by modifying base plastics through physical or chemical methods. This modification aims to improve the performance of plastics and meet the needs of different applications. The modification process usually involves adding different additives or fillers, such as plasticizers, antioxidants, stabilizers, reinforcing fibers, inorganic fillers, etc., or changing the molecular structure of the polymer to change its mechanical, thermal, and chemical properties. Modified plastic granules usually have better heat resistance, weather resistance, corrosion resistance, impact resistance, mechanical strength, and electrical insulation properties.

[0003] Existing modified plastic granules still present some problems during processing. For example, most modified plastic granules require packaging in ton bags after production. However, some plastic granules tend to stick together due to production processes or environmental factors, causing blockages at the discharge port during ton bag packaging. This requires frequent manual unblocking, which not only reduces efficiency but also increases operational complexity. Furthermore, directly packaging sticky granules may affect the appearance and quality of the finished product, posing potential risks for subsequent quality inspection. Moreover, most equipment lacks an effective bag opening mechanism, making it difficult for the packaging bag to stably and evenly receive the granules, further exacerbating packaging difficulties. At the same time, insufficient automation and reliance on manual operation in the sealing process restrict overall packaging efficiency and production continuity.

[0004] To address these issues, we provide a ton bag packaging device for modified plastic granules. Summary of the Invention

[0005] The purpose of this invention is to provide a ton bag packaging device for modified plastic granules. By cooperating with the feeding component and the packaging component, it solves the problems in the prior art where modified plastic granules are easily blocked by adhesion at the feeding port and it is inconvenient to open the packaging bag, thus affecting packaging efficiency.

The feeding plate slides back and forth under the action of the pressure plate and spring, realizing uniform and controllable conveying of granules and significantly reducing the frequency of manual unblocking. In addition, the inclined surface design at the bottom of the feeding port further optimizes the granule guidance and ensures that the material enters the conveyor frame smoothly, thereby improving packaging efficiency and ensuring the quality of finished products.

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Please see Figures 1-5 This utility model relates to a ton bag packaging device for modified plastic granules, comprising a conveyor frame 1, an internal conveyor belt with its own drive system for conveying the plastic granules after feeding, a concave frame 2 on one side of the conveyor frame 1 with openings on both sides of the bottom for placing or removing packaging bags, a feeding box 3 on the top side of the conveyor frame 1, a feeding assembly inside the feeding box 3 including a dispersing rod 4 movably connected to the inner cavity of the feeding box 3, with dispersing blades fixedly connected to the surface of the dispersing rod 4 for dispersing the bonded granules, a feeding port 5 on the bottom side of the feeding box 3, the feeding port 5 being elongated and close to but not in contact with the surface of the conveyor belt of the conveyor frame 1, and a feeding plate 6 slidably connected to the inner cavity of the feeding port 5, the feeding plate 6 being reciprocating to facilitate the feeding of the granules. The feeding assembly performs quantitative feeding, and a pressure plate 7 is fixedly connected to the top side of the feeding plate 6. The pressure plate 7 is squeezed by the cam 11 to complete the reciprocating movement of the feeding plate 6. The feeding assembly is used to uniformly feed plastic granules onto the surface of the conveyor belt. The inner cavity of the concave frame 2 is equipped with a packaging assembly, which includes a bidirectional screw 8 movably connected to the top side of the concave frame 2. A limit rod is fixedly connected to one side of the inner cavity of the concave frame 2. The surface of the limit rod is slidably connected to one side of the inner cavity of the support plate 9 to limit the support plate 9. The support plate 9 is threaded to both sides of the surface of the bidirectional screw 8, and an anti-slip strip 10 is fixedly connected to the bottom of one side of the support plate 9. The combination of the support plate 9 and the anti-slip strip 10 can open the bag mouth and stabilize the bag mouth. Since the granules conveyed by the conveyor frame 1 are uniform and do not accumulate, the bag mouth will not fall off through these two structures. The packaging assembly is used to open and heat-seal the packaging bag.

[0029] Example 2

[0030] Please see Figures 1-5Based on Example 1, a cam 11 is fixedly connected to one side of the surface of the dispersing rod 4, and a spring 12 is fixedly connected to one side of the pressure plate 7. The function of the spring 12 is to reset the feeding plate 6. One end of the spring 12 is fixedly connected to one side of the discharge port 5. A limiting plate 13 is fixedly connected to the bottom of the discharge box 3. A limiting port is opened on one side of the inner cavity of the limiting plate 13. The limiting plate 13 and the limiting port can support and limit the feeding plate 6. An extension opening is opened on the top of one side of the limiting plate 13 so that the cam 11 can rotate normally. The inner cavity of the limiting port is slidably connected to the surface of the feeding plate 6. A cylinder 14 is fixedly connected to one side of the concave frame 2. A heat sealing machine 15 is fixedly connected to the free end of the cylinder 14. Both the cylinder 14 and the heat sealing machine 15 are existing structures that can seal the bag opening, and will not be described in detail here. When sealing, first make The support plate 9 moves a certain distance relative to the support plate 9. At this time, the sealing structure of the heat sealing machine 15 will not contact the support plate 9, and the bag opening will be slightly loosened, making it convenient to seal. The top of the feeding box 3 is fixedly connected to the first motor 16. The output end of the first motor 16 is fixedly connected to one end of the dispersing rod 4. The top of one side of the concave frame 2 is fixedly connected to the second motor 17. The output end of the second motor 17 is fixedly connected to one end of the bidirectional lead screw 8. An inclined surface 18 is opened on one side of the bottom of the feeding port 5. The inclined surface 18 can guide the plastic particles. The top of one side of the feeding box 3 is opened to the feed port 19. The inclined feed port 19 is convenient for guiding materials and convenient for connecting with the external conveying structure. The feed port 19 is inclined. A bracket 20 is fixedly connected to one side of the top of the conveying frame 1. The inner cavity of the bracket 20 is fixedly connected to the surface of the feeding box 3.

[0031] The working principle of this utility model is as follows: Modified plastic granules first enter the inner cavity of the feeding box 3 through the inclined feed port 19. The first motor 16 drives the dispersing rod 4 to rotate at high speed. The dispersing blades on its surface mechanically crush the bonded granules. At the same time, the cam 11 fixed on the dispersing rod 4 periodically squeezes the pressure plate 7 as it rotates, forcing the feeding plate 6 to slide back and forth within the limiting port of the limiting plate 13. At this time, the spring 12 provides the restoring force, forming an intermittent quantitative feeding mechanism.

[0032] The dispersed particles fall through the feed inlet 5 under gravity. The inclined surface 18 at the bottom optimizes the flow direction of the particles, ensuring that the material is evenly spread on the conveyor belt of the conveyor frame 1. At the same time, the operator puts the bag opening into the concave frame 2. The second motor 17 drives the bidirectional screw 8 to rotate, which drives the two side support plates 9 to move outward synchronously. The friction between the anti-slip strip 10 and the inner wall of the bag opening is used to stably open the bag. After the conveyor belt delivers the quantitative particles into the bag, the cylinder 14 pushes the heat sealer 15 to press down. While the support plates 9 slightly retract to avoid the blockage, the heat seal of the bag opening is completed. The entire process is fully automated packaging operation from particle feeding, anti-blocking dispersion, quantitative conveying, bag opening fixing to automatic sealing through the coordinated cooperation of the dispersion rod 4 anti-blocking structure, the precise and controllable feeding mechanism, the bidirectional adjustable bag opening opening device and the automatic heat sealing system.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
