Description

Technical Field

[0001] This utility model relates to the field of plastic pellet processing technology, specifically to a recycled plastic pellet processing device. Background Technology

[0002] Recycled plastic raw materials mostly come from recycled products from different sources (such as packaging, building materials, and appliance casings), and often have uneven color. Mixing devices can fully blend recycled granules or masterbatches of different colors through stirring to ensure that the finished product has a uniform color and meets the appearance requirements of downstream applications.

[0003] After the existing plastic granules are mixed, workers need to manually open the discharge valve to bag them. During this process, they need to continuously support the bag opening with both hands to ensure that the granules enter the bag smoothly. This not only easily leads to fatigue due to prolonged arm strain, but also makes it difficult for a single person to balance the discharge speed and the precise positioning of the bag opening, resulting in occasional granule spillage. After bagging, the discharge valve must be manually closed immediately. After the full bags are transferred to a designated area, the discharge valve is reopened for the next round of bagging. This operation mode of frequent opening and closing of the discharge port not only increases the operation steps and prolongs the single bagging cycle, but also causes dust carried by the plastic granules to drift out from the gap between the bag opening and the discharge port during the discharge process, polluting the working environment and affecting the health of workers. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a recycled plastic pellet processing device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a recycled plastic pellet processing device, comprising a base, a mixing cylinder fixed to the top of the base by a support frame, an installation cylinder provided on the inner side of the support frame, a lead screw installed inside the installation cylinder, a servo motor installed on one side of the support frame, and the output end of the servo motor connected to one end of the lead screw, a threaded block threadedly connected to the outer surface of the lead screw, a movable plate fixed to the outer surface of the threaded block by a connecting plate, a bag support frame fixed to the top of the movable plate by a support rod, and a hanging nail fixed to the top of the bag support frame; a dust collection assembly provided on the outer surface of the mixing cylinder, the dust collection assembly including a fixed plate, a chip collection box provided on the top of the fixed plate, an exhaust fan mounted on one side of the chip collection box, a chip collection pipe mounted on the other side of the chip collection box, a filter element installed inside the chip collection box, a drive motor installed at the bottom of the mixing cylinder, a drive shaft connected to the output end of the drive motor, and a stirring blade installed on the outer surface of the drive shaft.

[0006] Furthermore, the top of the base is provided with a sliding groove, and the bottom of the movable plate is fixed with a sliding strip, and the bottom of the movable plate slides in cooperation with the sliding groove through the sliding strip.

[0007] By adopting the above technical solution, it is ensured that the movable plate moves smoothly along a fixed path when it moves the packaging bag, thus avoiding misalignment of the filling caused by deviation.

[0008] Furthermore, a step is provided on one side of the top of the base.

[0009] By adopting the above technical solutions, convenient support is provided for workers to load materials, effectively reducing the physical exertion caused by actions such as tiptoeing during loading.

[0010] Furthermore, a discharge port is provided on one side of the bottom of the mixing cylinder, and a valve plate is provided inside the discharge port.

[0011] By adopting the above technical solution, the discharge port provides a stable discharge channel for the mixed plastic granules, and the discharge start and stop are precisely controlled by the valve plate.

[0012] Furthermore, the bottom end of the chip collecting pipe is connected to a chip collecting cover, and the chip collecting cover is located directly above the discharge port.

[0013] By adopting the above technical solutions, it is ensured that the scattered dust enters the dust collection box efficiently, which greatly improves the dust collection rate and further protects the cleanliness of the working environment and the respiratory health of the staff.

[0014] Furthermore, a control panel is provided in the middle of the outer surface of the mixing cylinder, and the servo motor, drive motor and exhaust fan are all electrically connected to the control panel.

[0015] By adopting the above technical solution, staff can control the servo motor, drive motor, and exhaust fan through the control panel.

[0016] Furthermore, the stirring blades are provided in two sets, and both sets of stirring blades are spiral-shaped.

[0017] By adopting the above technical solution, the spiral blades drive the plastic particles to tumble and convect fully along the axial and radial directions, avoiding the mixing dead zones that are easily generated by single-group stirring, and greatly improving the mixing uniformity of multi-component particles.

[0018] Furthermore, the bag support frame is provided in two sets, and both sets of bag support frames are in the shape of a "U".

[0019] By adopting the above technical solution, the "U"-shaped structure fits the annular contour of the packaging bag opening, stably opening the bag opening to replace manual support. The two sets of bag support frames can respectively carry empty and full bags. With the movement of the movable plate, the material loading station can be quickly switched, allowing the material loading and bag changing actions to be seamlessly connected, further ensuring the continuity of material discharge and bagging, and improving the overall operation efficiency.

[0020] Furthermore, the outer surface of the chip collection box is provided with a sealing door, and the top of the mixing cylinder is provided with a cylinder cover.

[0021] By adopting the above technical solution, the sealing door on the dust collection box can maintain the airtightness of the box during dust collection operations, ensuring stable negative pressure to ensure dust collection efficiency. When the dust accumulates to a certain amount, the staff can easily open the sealing door for centralized cleaning. The cylinder cover on the top of the mixing cylinder can prevent plastic particles or dust from drifting out of the cylinder opening during the mixing process.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model, equipped with a bag support frame, lead screw, threaded block, connecting plate, movable plate, and hanging nails, allows workers to simply flip the openings of two packaging bags onto the bag support frame during bag filling. The hanging nails then provide stable fixation for the bag openings, eliminating the need for continuous hand support. Workers then open the valve plate, and the discharge port begins filling one of the packaging bags. Once one bag is filled, the servo motor drives the lead screw to rotate, which, through the transmission of the threaded block and connecting plate, causes the movable plate to move smoothly, allowing the other empty packaging bag to quickly and accurately move to the area directly below the discharge port for further filling. While the empty bag is being filled, workers can simultaneously transfer the full-filled bag and replace it with a new empty bag, achieving seamless connection between filling and bag changing. This significantly shortens the interval between bag fillings and greatly improves the overall discharge efficiency of the mixing drum.

[0024] 2. This utility model, by incorporating a dust extraction component, allows the exhaust fan to continuously draw air from the inside of the chip collection box during material discharge operations, quickly creating a stable negative pressure field within the box. This negative pressure can be transmitted to the chip collection hood through the chip collection pipe, efficiently capturing and guiding the easily dispersed dust into the chip collection box, preventing dust from spreading into the working environment. The filter element inside the chip collection box can precisely intercept the dust, ensuring that the dust is retained and collected within the box. This protects the respiratory health of workers and provides clean and safe working conditions for continuous industrial production. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] Example 1: A device for processing recycled plastic pellets, such as Figures 1-5As shown, the system includes a base 1, with a mixing cylinder 3 fixed to the top of the base 1 via a support frame 2. An installation cylinder 7 is located inside the support frame 2, and a lead screw 14 is installed inside the installation cylinder 7. A servo motor 13 is installed on one side of the support frame 2, and the output end of the servo motor 13 is connected to one end of the lead screw 14. A threaded block 15 is threaded onto the outer surface of the lead screw 14. A movable plate 8 is fixed to the outer surface of the threaded block 15 via a connecting plate 16. A bag support frame 18 is fixed to the top of the movable plate 8 via a support rod 17. Two sets of bag support frames 18 are provided, both in a "U" shape. The "U" shape conforms to the annular contour of the bag opening, stably opening the bag to replace manual support. The two sets of bag support frames 18 can respectively carry empty and full bags. Combined with the displacement of the movable plate 8, the filling station can be quickly switched, allowing seamless connection between filling and bag changing actions, further ensuring the smooth operation of the material discharge process. The continuity of the bags improves overall work efficiency. The top of the bag support frame 18 is fixed with a hanging nail 19. The outer surface of the mixing cylinder 3 is provided with a dust collection component 5. The dust collection component 5 includes a fixing plate 501. The top of the fixing plate 501 is provided with a chip collection box 502. A fan 503 is mounted on one side of the chip collection box 502. A chip collection pipe 505 is installed on the other side of the chip collection box 502. A filter element 504 is installed inside the chip collection box 502. The bottom end of the chip collection pipe 505 is connected to a chip collection cover 506. The chip collection cover 506 is located directly above the discharge port 12 to ensure that the scattered dust enters the chip collection box 502 efficiently, greatly improving the dust collection rate and further ensuring the cleanliness of the working environment and the respiratory health of the workers. The bottom of the mixing cylinder 3 is provided with a drive motor 9. The output end of the drive motor 9 is connected to a drive shaft 10. The outer surface of the drive shaft 10 is provided with a stirring blade 11.

[0034] See Figures 1-2 In the above embodiment, a discharge port 12 is provided on one side of the bottom of the mixing cylinder 3, and a valve plate is provided inside the discharge port 12. The discharge port 12 provides a stable discharge channel for the mixed plastic particles, and the discharge start and stop are precisely controlled by the valve plate.

[0035] See Figure 1 In the above embodiment, the mixing cylinder 3 has a control panel 4 in the middle of its outer surface, and the servo motor 13, drive motor 9 and exhaust fan 503 are all electrically connected to the control panel 4. The operator can control the servo motor 13, drive motor 9 and exhaust fan 503 through the control panel 4.

[0036] See Figure 2 In the above embodiment, the stirring blades 11 are provided in two sets, and both sets of stirring blades 11 are spiral in shape. The spiral blades drive the plastic particles to tumble and convect fully along the axial and radial directions, avoiding the mixing dead corners that are easy to be generated by single-set stirring, and greatly improving the mixing uniformity of multi-component particles.

[0037] See Figure 1 In the above embodiment, the outer surface of the chip collection box 502 is provided with a sealing door, and the top of the mixing cylinder 3 is provided with a cylinder cover. The sealing door on the chip collection box 502 can keep the box airtight during dust collection operations, ensure stable negative pressure to ensure dust collection efficiency. When the dust accumulates to a certain amount, the staff can easily open the sealing door for centralized cleaning. The cylinder cover on the top of the mixing cylinder 3 can prevent plastic particles or dust from drifting out of the cylinder opening during the mixing process.

[0038] Example 2: To make the movable plate more stable during displacement, Example 2 is an improvement on Example 1. (See attached document.) Figure 1 and Figure 5 The base 1 has a groove 21 on its top, and a slide bar 20 is fixed on the bottom of the movable plate 8. The bottom of the movable plate 8 slides with the groove 21 through the slide bar 20, ensuring that the movable plate 8 moves smoothly along a fixed path when it moves the packaging bag, thus avoiding misalignment of the filling caused by deviation.

[0039] Example 3: To make material loading more convenient for workers, Example 3 is an improvement on Example 1. (See attached document.) Figure 1 and Figure 5 The base 1 has a step 6 on one side of its top, which provides convenient support for workers to load materials and effectively reduces the physical exertion caused by tiptoeing and other actions when loading materials.

[0040] The implementation principle of this utility model is as follows: Before operation, the operator can open the cylinder cover using the step 6 to add plastic granules of different colors. After closing the cylinder cover, the operator starts the drive motor 9 via the control panel 4. The drive motor 9 drives the drive shaft 10 and two sets of spiral stirring blades 11 to rotate, causing the plastic granules of different colors to tumble and convect fully along the axial and radial directions, effectively avoiding dead corners in the mixing process and ensuring that the granules of each color are evenly mixed. After mixing, the openings of the two packaging bags are respectively folded over and fitted onto the two sets of "U"-shaped bag support frames 18, and the bag openings are fixed with hanging nails 19. Then, the valve plate inside the discharge port 12 is opened via the control panel 4, and the exhaust fan 503 is started. The exhaust fan 503 draws air from the chip collection box 502 to create negative pressure. At this time, the plastic granule dust floating in the gap between the discharge port 12 and the bag opening is collected by the chip collection box. The dust collector 506 and dust collection pipe 505 enter the dust collection box 502, where they are intercepted and collected by the filter element 504 (the filter element 504 is made of polyester fiber, with a filtration accuracy of 0.3 microns and a filtration efficiency of ≥99.97%). The discharge port 12 fills one of the packaging bags. When the packaging bag is full, the servo motor 13 is started through the control panel 4. The servo motor 13 drives the lead screw 14 to rotate, so that the threaded block 15 drives the movable plate 8 through the connecting plate 16. With the help of the sliding cooperation between the bottom slide bar 20 and the slide groove 21, the movable plate 8 is moved smoothly along a fixed path, and the other empty packaging bag is accurately moved to the bottom of the discharge port 12 to continue filling. At this time, the staff can simultaneously transfer the full bag and replace it with a new empty bag. After the mixing is completed, the staff can open the sealed door to clean and maintain the dust collection box 502 and the filter element 504.
