Description

Technical Field

[0001] This utility model relates to the field of flame retardant masterbatch production, and in particular to a quantitative packaging device for flame retardant masterbatch. Background Technology

[0002] In the production and processing of flame retardant masterbatches, quantitative packaging is a crucial step before products leave the factory. Its packaging accuracy, efficiency, and stability directly affect product quality and market competitiveness. Currently, the industry mostly uses semi-automated equipment or manual assistance for quantitative packaging of flame retardant masterbatches, which presents many technical challenges that urgently need to be addressed.

[0003] On the one hand, existing packaging equipment relies on manual intervention for the positioning and transfer of flame retardant masterbatch loading bottles. Empty bottles must be manually placed at designated stations and their positions adjusted to align with the feeding port. This process is not only cumbersome and time-consuming, but also prone to errors due to human intervention, leading to misalignment between the bottle opening and the feeding port, resulting in spillage of the flame retardant masterbatch, wasting raw materials and polluting the production environment. Furthermore, the manual transfer of loading bottles is inefficient and unsuitable for large-scale production, and labor costs increase significantly with the expansion of production scale.

[0004] On the other hand, the quantitative feeding accuracy of existing equipment is difficult to guarantee. Some equipment uses a single valve to control the feeding amount, lacking real-time weight feedback and dynamic adjustment mechanisms. This makes it prone to fluctuations in feeding amount due to uneven particle size of flame retardant masterbatch and clumping caused by moisture, failing to meet the precise quantitative requirements of different product specifications. Although some equipment is equipped with weighing components, the unstable positioning of the loaded bottles and the shaking of the bottles during the weighing process can easily cause deviations in the weighing data, further affecting the quantitative accuracy. In addition, the storage mechanism often experiences blockage of the feeding channel by flame retardant masterbatch during long-term use, requiring manual shutdown for cleaning, which seriously affects production continuity and reduces overall packaging efficiency.

[0005] Furthermore, existing packaging equipment lacks versatility and ease of maintenance. Most equipment is only compatible with a single size of bottle, and changing packaging sizes requires disassembling and replacing multiple parts, which is complex and costly.

[0006] In summary, current flame retardant masterbatch quantitative packaging equipment suffers from problems such as low automation, poor quantitative accuracy, insufficient versatility, and inconvenient maintenance, making it difficult to meet the demands of modern, large-scale production for efficient, accurate, and stable packaging.

[0007] Therefore, it is necessary to provide a quantitative packaging device for flame retardant masterbatch to solve the above-mentioned technical problems. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides a quantitative packaging equipment for flame retardant masterbatch.

[0009] This utility model provides a quantitative packaging equipment for flame retardant masterbatch, including a mounting frame and mounting plates installed around the mounting frame. A rotating mechanism is installed at the bottom of the center of the mounting frame, and a feeding mechanism, a quantitative feeding mechanism, a packaging mechanism, and a discharging mechanism are installed on the top of the four mounting plates in a counterclockwise direction.

[0010] The rotating mechanism includes a geared motor, the top of which is fixedly connected to a mounting frame. The output end of the geared motor passes through the mounting frame and is fixedly connected to a support plate. The geared motor drives the support plate to rotate. Several evenly arranged ring-shaped locking rings are fixedly connected to the top of the support plate. These locking rings are used to restrict the loading of the flame-retardant masterbatch bottles. A weighing device is installed inside each locking ring to weigh the flame-retardant masterbatch bottles. An electric telescopic rod is fixedly connected to the top of the center of the support plate. This electric telescopic rod can drive a limiting plate to adjust its height to accommodate bottles of different heights. A limiting plate is fixedly connected to the top of the electric telescopic rod. The top has a limiting port that corresponds one-to-one with several locking rings. The limiting port is used to restrict the position of the loading bottle. A miniature electric push rod is symmetrically fixedly connected to the inner wall of the limiting port. A push block is fixedly connected to the output end of the miniature electric push rod. The push block is used to adjust the position of the loading bottle. The surface of the push block is covered with a rubber pad. The push block is used to facilitate the alignment of the bottle mouth with the output end of the quantitative feeding mechanism. When loading flame retardant masterbatch into the loading bottle, the push block needs to return to its original position after correcting the position of the loading bottle, so as to avoid the weighing device being unable to weigh the bottle when the push block clamps the loading bottle. At the same time, when sealing the loading bottle, the push block is needed to clamp the loading bottle so as to locate its position.

[0011] Furthermore, the quantitative feeding mechanism includes a support bar, and a lifting groove is provided on the side of the support bar near the rotating mechanism. A lead screw is rotatably connected inside the lifting groove via a bearing. A lifting motor is fixedly connected inside the support bar, and the output end of the lifting motor is fixedly connected to the lead screw via a coupling. A lifting block is threadedly connected to the surface of the lead screw, and the surface of the lifting block is slidably connected to the lifting groove, so that the lifting block can be vertically lifted and lowered along the axis of the lead screw. A bearing component is fixedly connected to the outside of the lifting block.

[0012] Furthermore, the supporting component includes a supporting plate, which is fixedly connected to the lifting block. A star valve is fixedly connected to the top of the supporting plate, and the top of the star valve is connected to a storage tank for storing flame retardant masterbatch. The star valve scrapes out the flame retardant masterbatch from the storage tank by rotating its blades, thereby achieving continuous unloading. The output end of the star valve passes through the supporting plate and is connected to a solenoid valve. The output end of the solenoid valve is used in conjunction with a limit port. The solenoid valve can accurately and quantitatively discharge the flame retardant masterbatch discharged from the star valve.

[0013] Furthermore, a maintenance door is provided on the back of the support bar, which is located behind the lifting motor. The maintenance door is used to maintain the lifting motor. Heat dissipation vents are symmetrically opened on both sides of the support bar and are used in conjunction with the lifting motor to dissipate heat from the lifting motor.

[0014] Furthermore, a stirring motor is fixedly connected to the top of the storage tank, and the output shaft of the stirring motor extends into the interior of the storage tank and is fixedly connected to a spiral blade. The spiral blade is used to prevent blockage when the storage tank discharges material.

[0015] Furthermore, the packaging mechanism includes a hydraulic telescopic rod, the output end of which is fixedly connected to a support frame. A winding shaft is symmetrically arranged on one side of the support frame near the rotating mechanism. A sealing film is wound around the surface of the winding shaft. A winding motor is fixedly connected to the outside of the support frame, and the output end of the winding motor is fixedly connected to one of the winding shafts. The winding motor drives one winding shaft to rotate and release the film, while the other winding shaft rotates synchronously to wind up the waste film, thus achieving continuous film supply and waste film recycling.

[0016] Furthermore, a support plate is fixedly connected to the top of the support frame, and a pressing rod is fixedly connected to the top of the support plate. A sealing mold is fixedly connected to the output end of the pressing rod. The sealing mold is used to cut the sealing film and heat seal the bottle mouth of the flame retardant masterbatch loading bottle.

[0017] Furthermore, the top of the mounting bracket is provided with a balancing groove, and the bottom of the bearing plate is fixedly connected with a balancing ring, which is rotatably connected to the balancing groove.

[0018] Furthermore, the rotating mechanism, feeding mechanism, quantitative feeding mechanism, packaging mechanism, and discharging mechanism are all controlled by an external controller.

[0019] Furthermore, both the feeding mechanism and the discharging mechanism can be robotic arms, one of which is used to load the flame retardant masterbatch loading bottle, and the other is used to unload the packaged flame retardant masterbatch loading bottle.

[0020] Compared with related technologies, the flame retardant masterbatch quantitative packaging equipment provided by this utility model has the following beneficial effects:

[0021] 1. This utility model utilizes a rotary positioning system comprised of a mounting frame, mounting plate, geared motor, bearing plate, snap ring, weighing device, electric telescopic rod, limit plate, limit port, miniature electric push rod, push block, and balance ring. This system, controlled by an external controller, enables automated flow and precise positioning of flame-retardant masterbatch loading bottles. The electric telescopic rod adjusts the height of the limit plate to accommodate bottles of varying heights. The miniature electric push rod drives the push block to correct the bottle opening position. The balance ring rotates along the balance groove of the mounting frame to ensure stable rotation of the bearing plate. Furthermore, it incorporates a star valve, solenoid valve, and storage device. The quantitative feeding system, consisting of a bucket, a stirring motor, and spiral blades, uses a stirring motor to drive the spiral blades to prevent clogging. A star valve continuously discharges the material, while a solenoid valve precisely controls the quantity. A weighing device provides real-time weight feedback. Compared to related technologies, which suffer from problems such as manual positioning, low feeding accuracy, and easy spillage, this invention achieves precise positioning of the loading bottle through a rotary positioning system. Combined with the real-time weighing and precise quantity control of the quantitative feeding system, the two work synergistically to significantly improve the positioning accuracy of the loading bottle and the quantitative feeding accuracy of the flame retardant masterbatch. At the same time, it achieves automated circulation and reduces the cost of manual intervention.

[0022] 2. This utility model utilizes an automatic packaging system comprised of a hydraulic telescopic rod, support frame, winding shaft, winding motor, support plate, pressing push rod, and sealing mold. Combined with a feeding mechanism (robotic arm) and a discharging mechanism (robotic arm), the hydraulic telescopic rod adjusts the position of the support frame to accommodate bottles of different diameters. The winding motor drives the winding shaft to unwind the sealing film, and the pressing push rod drives the sealing mold to simultaneously complete cutting and heat sealing. The robotic arm enables automatic loading and unloading. Simultaneously, the support bar's heat dissipation vents provide cooling for the lifting motor, and the maintenance door facilitates inspection. All mechanisms work collaboratively via an external controller. Compared to related technologies where packaging requires manual film placement and sealing, and loading and unloading rely on manual labor, resulting in inconvenient equipment maintenance, this system achieves full automation from robotic arm empty bottle loading, rotating mechanism positioning and flow, quantitative feeding mechanism precise loading, packaging mechanism automatic sealing, to robotic arm finished product unloading. This improves packaging efficiency and sealing performance, extends equipment lifespan, and reduces maintenance difficulty. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] Please refer to the following: Figures 1 to 6 A flame-retardant masterbatch quantitative packaging equipment includes a mounting frame 1, mounting plates 2 installed around the mounting frame 1, a rotating mechanism installed at the bottom center of the mounting frame 1, and a feeding mechanism, a quantitative feeding mechanism, a packaging mechanism and a discharge mechanism installed on the top of the four mounting plates 2 in a counterclockwise direction.

[0032] The rotating mechanism includes a geared motor 3, the top of which is fixedly connected to the mounting frame 1. The output end of the geared motor 3 passes through the mounting frame 1 and is fixedly connected to a bearing plate 4. The geared motor 3 drives the bearing plate 4 to rotate. Several evenly arranged ring-shaped locking rings 5 ​​are fixedly connected to the top of the bearing plate 4. The locking rings 5 ​​are used to restrict the loading of the flame retardant masterbatch bottles. A weighing device 6 is installed inside the locking rings 5 ​​to weigh the flame retardant masterbatch loading bottles. An electric telescopic rod 7 is fixedly connected to the top of the center of the bearing plate 4. The electric telescopic rod 7 can drive the limiting plate 8 to adjust its height to accommodate loading bottles of different heights. The top of the electric telescopic rod 7 is fixedly connected to the limiting plate 8, and the top of the limiting plate 8 has a... A limiting port 9 is provided, corresponding one-to-one with several snap-fit ​​rings 5. The limiting port 9 is used to limit the position of the loading bottle body. A miniature electric push rod 10 is symmetrically fixedly connected to the inner wall of the limiting port 9. A push block 11 is fixedly connected to the output end of the miniature electric push rod 10. The push block 11 is used to adjust the position of the loading bottle. A rubber pad is provided on the surface of the push block 11. The push block 11 is used to facilitate the alignment of the bottle mouth of the loading bottle with the output end of the quantitative feeding mechanism. When loading flame retardant masterbatch into the loading bottle, the push block 11 needs to be returned to its original position after correcting the position of the loading bottle. This is to avoid the weighing device 6 being unable to weigh the bottle when the push block 11 clamps the loading bottle. At the same time, when the loading bottle is sealed, the push block 11 is needed to clamp the loading bottle so that its position can be positioned.

[0033] In the specific implementation process, the rotating mechanism drives the loading bottle to pass through the feeding mechanism, quantitative feeding mechanism, packaging mechanism and discharge mechanism in sequence, realizing the automated flow of flame retardant masterbatch loading bottles from feeding, quantitative filling, sealing to unloading, which greatly improves packaging efficiency and reduces manual intervention costs.

[0034] refer to Figure 1 , Figure 3 and Figure 6 As shown, the quantitative feeding mechanism includes a support bar 12. A lifting groove is provided on the side of the support bar 12 near the rotating mechanism. A lead screw 13 is rotatably connected inside the lifting groove through a bearing. A lifting motor 14 is fixedly connected inside the support bar 12. The output end of the lifting motor 14 is fixedly connected to the lead screw 13 through a coupling. A lifting block 15 is threadedly connected to the surface of the lead screw 13. The surface of the lifting block 15 is slidably connected to the lifting groove, so that the lifting block 15 can be vertically lifted along the axis of the lead screw 13. A bearing component is fixedly connected to the outside of the lifting block 15.

[0035] The supporting component includes a supporting plate 16, which is fixedly connected to a lifting block 15. A star valve 17 is fixedly connected to the top of the supporting plate 16. The top of the star valve 17 is connected to a storage tank 18 for storing flame retardant masterbatch. The star valve 17 scrapes out the flame retardant masterbatch in the storage tank 18 by rotating its blades, thus achieving continuous unloading. The output end of the star valve 17 passes through the supporting plate 16 and is connected to a solenoid valve 19. The output end of the solenoid valve 19 is used in conjunction with the limit port 9. The solenoid valve 19 can accurately and quantitatively discharge the flame retardant masterbatch discharged from the star valve 17. The external controller calculates the target total weight based on the weight of the empty bottle and the preset quantitative value of the flame retardant masterbatch. When the weighing device 6 detects that the weight of the loaded bottle reaches the target total weight, it controls the solenoid valve 19 to close.

[0036] A maintenance door is provided on the back of the support bar 12. The maintenance door is located on the rear side of the lifting motor 14. The maintenance door is used to maintain the lifting motor 14. Heat dissipation vents are symmetrically opened on both sides of the support bar 12. The heat dissipation vents are used in conjunction with the lifting motor 14 to dissipate heat from the lifting motor 14.

[0037] A stirring motor 20 is fixedly connected to the top of the storage tank 18. The output shaft of the stirring motor 20 extends into the interior of the storage tank 18 and is fixedly connected to a spiral blade 21. The spiral blade 21 is used to prevent blockage when the storage tank 18 discharges material.

[0038] It should be noted that in the quantitative feeding mechanism, the lifting motor 14 drives the lead screw 13 to rotate, which drives the lifting block 15 and the bearing component to rise and fall synchronously. The distance between the output end of the solenoid valve 19 and the bottle opening can be adjusted according to the height of the loading bottle to avoid the leakage of flame retardant masterbatch during the feeding process and improve the filling accuracy.

[0039] It should be noted that the star valve 17 enables continuous conveying of flame-retardant masterbatch. Combined with the on / off control of the solenoid valve 19, it can accurately control the amount of material fed at one time based on the weight data fed back by the weighing device 6, meeting the quantitative packaging requirements of different specifications and having a wider range of applications.

[0040] It should be noted that the stirring motor 20 drives the spiral blades 21 to rotate inside the storage tank 18, which can stir and loosen the flame retardant masterbatch inside the storage tank 18, prevent the flame retardant masterbatch from getting damp and caking, causing blockage of the discharge channel, and ensure the continuous and stable operation of the equipment.

[0041] It should be noted that the maintenance door on the back of the support bar 12 facilitates the maintenance and replacement of the lifting motor 14 by the staff, and the heat dissipation vents on both sides can dissipate the heat generated by the lifting motor 14 during operation in a timely manner, thereby extending the service life of the lifting motor 14 and reducing the probability of equipment failure.

[0042] refer to Figure 1 , Figure 3 and Figure 5 As shown, the packaging mechanism includes a hydraulic telescopic rod 22. A support frame 23 is fixedly connected to the output end of the hydraulic telescopic rod 22. A winding shaft 24 is symmetrically arranged on the side of the support frame 23 near the rotating mechanism. A sealing film is wound on the surface of the winding shaft 24. A winding motor is fixedly connected to the outside of the support frame 23, and the output end of the winding motor is fixedly connected to one of the winding shafts 24. The winding motor drives the winding shaft 24 on one side to rotate and release the film, while the winding shaft 24 on the other side rotates synchronously to wind up the waste film, thereby realizing continuous film supply and waste film recycling. A support plate is fixedly connected to the top of the support frame 23. A pressing push rod 26 is fixedly connected to the top of the support plate. A sealing mold 27 is fixedly connected to the output end of the pressing push rod 26. The sealing mold 27 is a mature existing technology, which is used to cut the sealing film and heat seal the bottle mouth of the flame retardant masterbatch loading bottle.

[0043] It should be noted that the hydraulic telescopic rod 22 can move the support frame 23 closer to or further away from the loading bottle, making it easy to adjust the sealing position according to the diameter of the loading bottle, adapting to the sealing needs of loading bottles of different specifications, and has strong versatility.

[0044] It should be noted that: the winding motor drives the winding shaft 24 to rotate, realizing the automatic unwinding of the sealing film. In conjunction with the downward push rod 26 to drive the lifting and lowering of the sealing mold 27, the sealing film cutting and bottle loading heat sealing can be completed simultaneously, simplifying the sealing process and improving sealing efficiency and sealing performance.

[0045] refer to Figure 3 As shown, the top of the mounting bracket 1 is provided with a balance groove, and the bottom of the bearing plate 4 is fixedly connected with a balance ring 25, and the balance ring 25 is rotatably connected to the balance groove.

[0046] It should be noted that when the carrier plate 4 rotates, the balance ring 25 rotates synchronously along the balance groove, which can support and guide the carrier plate 4, prevent the carrier plate 4 from tilting or shaking due to uneven weight of the bottles loaded on top, ensure the stability of the carrier plate 4 during rotation, and thus improve the accuracy of subsequent filling and sealing.

[0047] refer to Figure 1 As shown, the rotating mechanism, feeding mechanism, quantitative feeding mechanism, packaging mechanism, and discharging mechanism are all controlled by an external controller;

[0048] Both the feeding mechanism and the discharging mechanism can be robotic arms. One robotic arm is used to load the flame retardant masterbatch loading bottles, and the other robotic arm is used to unload the packaged flame retardant masterbatch loading bottles.

[0049] It should be noted that centralized control of each mechanism through an external controller can achieve coordinated operation of the mechanisms. For example, the rotation speed of the rotating mechanism can be matched with the feeding speed of the quantitative feeding mechanism, and the start and stop linkage between the packaging mechanism and the rotating mechanism can be achieved, thereby reducing human operation errors and realizing fully automated operation of the equipment.

[0050] It should be noted that using a robotic arm as the feeding and unloading mechanism can accurately complete the gripping, placement and unloading of the loaded bottles. Compared with manual loading and unloading, it not only improves the efficiency of loading and unloading, but also avoids collision damage to the flame retardant masterbatch loaded bottles during manual handling, thus ensuring the quality of product packaging.

[0051] The working principle of the flame-retardant masterbatch quantitative packaging equipment provided by this utility model is as follows:

[0052] After the equipment is started, the external controller controls the feeding mechanism (robotic arm) to place the flame retardant masterbatch loading bottle into the snap ring 5 on the top of the support plate 4 on the mounting frame 1. After the initial weighing is completed, the weighing device 6 transmits the weight data of the empty bottle to the external controller as the weight benchmark for subsequent quantitative feeding. At the same time, the weighing device 6 installed inside the snap ring 5 begins the initial weighing. The electric telescopic rod 7 at the top of the center of the support plate 4 extends and retracts according to the height of the loading bottle, driving the limiting plate 8 to adjust to the appropriate height, so that the loading bottle passes through the limiting port 9 on the limiting plate 8, which corresponds one-to-one with the snap ring 5. Then, the miniature electric push rod 10, which is symmetrically fixed to the inner wall of the limiting port 9, pushes the push block 11 to adjust the position of the loading bottle. First, ensure the bottle opening is aligned with the output end of the quantitative feeding mechanism. After alignment, push block 11 returns to its original position. Then, reducer motor 3 starts, and its output end drives the bearing plate 4 to rotate. The balance ring 25 at the bottom of the bearing plate 4 rotates synchronously along the balance groove at the top of the mounting frame 1 to maintain stability. When the loaded bottle rotates with the bearing plate 4 to below the quantitative feeding mechanism, lifting motor 14 inside support bar 12 starts. Its output end drives the lead screw 13 in the lifting groove to rotate through the coupling, causing the lifting block 15 threaded on the surface of the lead screw 13 to slide along the lifting groove. This drives the bearing plate 16 and bearing assembly fixedly connected to the outside of the lifting block 15 to rise and fall as a whole, adjusting to the point where the output end of the star valve 17 at the bottom of the storage tank 18 is connected. The solenoid valve 19 is matched to the height of the bottle opening. The stirring motor 20 on the top of the storage tank 18 starts, and its output shaft drives the internal spiral blades 21 to rotate to prevent the flame retardant masterbatch from clogging. The star valve 17 scrapes out the flame retardant masterbatch from the storage tank 18 through the rotation of the blades. The solenoid valve 19 then quantitatively feeds the masterbatch into the bottle. At the same time, the weighing device 6 weighs the masterbatch in real time. Once the set weight is reached, the solenoid valve 19 closes. Then, the reduction motor 3 continues to drive the bearing plate 4 to rotate, sending the bottle containing the flame retardant masterbatch to the bottom of the packaging mechanism. At this time, the hydraulic telescopic rod 22 extends and retracts, driving the support frame 23 to adjust to the appropriate position. The winding motor on the outside of the support frame 23 drives the winding shaft 24 on one side to rotate, so that the winding shaft 24 is rotated. The rolled-up packaging film unfolds, and the downward push rod 26 on the top support plate of the support frame 23 pushes the sealing mold 27 down to cut the packaging film and heat seal the loaded bottle. During the packaging process, the micro electric push rod 10 pushes the push block 11 again to clamp the loaded bottle for positioning. After the packaging is completed, the geared motor 3 drives the carrier plate 4 to rotate the finished bottle to the discharge mechanism (robotic arm). The discharge mechanism unloads the finished bottle and completes one packaging cycle. In the above process, the rotating mechanism, feeding mechanism, quantitative feeding mechanism, packaging mechanism and discharge mechanism are all controlled by an external controller. The heat dissipation vents on both sides of the support bar 12 are for heat dissipation of the lifting motor 14, and the maintenance door on the back facilitates the maintenance of the lifting motor 14.

[0053] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
