Description

An automatic dispensing device for finished PC plastic granules Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to an automatic packaging device for finished PC plastic granules. Background Technology

[0002] PC plastic granules, or polycarbonate plastic granules, are a high-performance engineering plastic raw material. They have high strength, high transparency, good impact resistance and heat resistance, and are widely used in many fields such as electronics, automobile manufacturing, medical devices, and optical lenses. In the production process of plastic products, PC plastic granules need to be packaged according to a certain weight or quantity for subsequent processing and use.

[0003] Automatic dispensing devices are mechanical equipment that can replace manual labor to automatically measure and dispense materials. They have significant advantages in improving dispensing efficiency, ensuring dispensing accuracy, and reducing labor intensity.

[0004] An existing automatic packaging device for finished PC plastic granules has the following shortcomings:

[0005] Firstly, the existing equipment has an unreasonable design for the placement and conveying structure of the dispensing barrels. Placing and removing the barrels is cumbersome, and the lack of effective limiting structures makes it easy for the barrels to shift or even slip during the dispensing process, leading to interruptions and reduced efficiency. Furthermore, traditional equipment often uses fixed workstations for dispensing; when loading or unloading full barrels, the equipment is idle and cannot perform other dispensing operations simultaneously, wasting considerable time and reducing overall dispensing efficiency. Secondly, the existing equipment's feeding structure is flawed. The distance between the discharge pipe and the dispensing barrel is fixed, and during dispensing, PC plastic granules are prone to splashing due to the drop, causing a large number of granules to scatter outside the dispensing barrel, resulting in material waste and increased production costs. Moreover, the discharge pipe lacks an automatic opening and closing control structure, requiring manual operation of the switch. This is not only inconvenient but also prone to failure, leading to granule leakage due to forgetting to close the discharge pipe, posing a safety hazard and affecting the accuracy and efficiency of dispensing. Summary of the Invention

[0006] This utility model proposes an automatic packaging device for finished PC plastic granules. By optimizing the packaging barrel placement and conveying structure and the automatic control feeding structure, it achieves efficient and stable packaging and reduces raw material waste, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an automatic packaging device for finished PC plastic granules, comprising a support base, a conveying component rotatably connected to the top of the support base, three support columns fixedly connected to the outer surface of the support base, a storage bin fixedly connected to the top of the three support columns, and a bin cover provided on the top of the storage bin.

[0008] The conveying assembly includes a rotating platform rotatably connected to the top of a support base. The top of the outer surface of the rotating platform has four U-shaped placement slots arranged in a circular array. The lower inner wall of each U-shaped placement slot is rotatably connected to several rollers. The left and right sides of the inner wall of each U-shaped placement slot have grooves. The inner surface of each groove is rotatably connected to a rotating stop post. The end of the rotating stop post away from the groove extends through to the front of the interior of the U-shaped placement slot.

[0009] Preferably, the conveying component includes a drive motor, a connecting groove is provided at the bottom center of the support base, the drive motor is fixedly connected inside the connecting groove, and the output shaft of the drive motor passes through to the top of the support base and is fixedly connected to the bottom center of the rotating platform.

[0010] Preferably, a discharge pipe is fixedly connected to the bottom rear side of the storage silo, and an extension pipe is slidably connected to the outer surface of the discharge pipe.

[0011] Preferably, a drive motor is fixedly connected to the bottom of the storage hopper, and a transmission screw is fixedly connected to the output shaft of the drive motor. A threaded slide is threadedly connected to the outer surface of the transmission screw, and the threaded slide is fixedly connected to the outer surface of the extension tube.

[0012] Preferably, a rotating column is rotatably connected to the bottom of the inner surface of the discharge pipe, a rotating baffle is fixedly connected to the middle of the rotating column, a connecting groove is opened on the front side of the inner surface of the extension pipe, and the front end of the rotating column passes through the interior of the connecting groove and is fixedly connected to a connecting slide plate.

[0013] Preferably, a sliding column is fixedly connected to the front left side of the connecting slide plate, a vertical groove is provided on the left side of the inner wall of the connecting slide, the sliding column is slidably connected inside the vertical groove, and an oblique groove is provided at the top of the vertical groove.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. In this utility model, through the cooperation of the rotating table, the U-shaped placement groove, the rollers, and the rotating stop, when dispensing PC plastic granules, the dispensing bucket is placed in the U-shaped placement groove. The rollers on the lower surface of the inner wall of the U-shaped placement groove can significantly reduce the friction between the dispensing bucket and the bottom of the groove. The operator only needs to apply slight force to easily push the dispensing bucket, making the loading and unloading of the dispensing bucket more convenient and efficient. After the dispensing bucket is placed in place, the rotating stop is rotated from the groove to the front of the U-shaped placement groove, and the rotating stop can form an effective barrier. To prevent the dispensing barrels from sliding out of the U-shaped placement trough during the dispensing process due to vibration or external force, ensuring the stability of the dispensing barrels, the drive motor rotates the turntable, enabling precise automatic rotation of the dispensing barrels. When one of the placement troughs is full, the turntable rotates to place the next empty dispensing barrel below the discharge port for further filling. At this time, the operator can load and unload the already filled dispensing barrels, realizing simultaneous loading and unloading of barrels and dispensing, greatly improving the overall dispensing efficiency and reducing equipment downtime.

[0016] 2. In this utility model, through the mutual cooperation between the discharge pipe, extension pipe, drive motor, transmission screw, threaded slide column, rotating column, rotating baffle, connecting slide plate, sliding column, vertical slide groove, and inclined slide groove, during the PC plastic granule filling process, the drive motor drives the transmission screw to rotate, and the threaded slide column moves on the transmission screw, thereby causing the extension pipe to extend and slide outside the discharge pipe. The extension length of the extension pipe can be flexibly adjusted according to the actual position of the dispensing bucket, so that the lower end of the extension pipe is close to the opening of the dispensing bucket, effectively shortening the falling distance of the PC plastic granules, avoiding granules splashing outside the bucket, and reducing the original This process avoids material waste. Simultaneously, as the extension tube slides, its sliding column slides in the vertical groove. When the sliding column reaches the inclined groove, it drives the connecting slide plate to rotate. The connecting slide plate, through the rotating column, drives the rotating baffle to rotate, thus automatically opening the discharge tube and achieving automatic filling of PC plastic granules. When filling is complete and the extension tube retracts, the sliding column slides in opposite directions along the inclined and vertical grooves, driving the rotating baffle to reset synchronously, achieving automatic closure of the discharge tube. The entire process requires no manual operation of the discharge tube switch, making operation convenient, improving the accuracy and safety of dispensing, and also increasing work efficiency.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As shown in Figures 1 and 2, this utility model provides a technical solution: including a support base 1, a conveying assembly 2 rotatably connected to the top of the support base 1, three support columns 3 fixedly connected to the outer surface of the support base 1, a storage bin 4 fixedly connected to the top of the three support columns 3, a bin cover 5 provided on the top of the storage bin 4, the conveying assembly 2 including a rotating platform 22, the rotating platform 22 being rotatably connected to the top of the support base 1, four U-shaped placement slots 23 arranged in a circular array on the top of the outer surface of the rotating platform 22, the inner of the U-shaped placement slots 23 being... The lower surface of the wall is rotatably connected to several rollers 24. The inner wall of the U-shaped placement groove 23 has grooves 25 on both the left and right sides. The inner surface of the groove 25 is rotatably connected to a rotating stop post 26. The end of the rotating stop post 26 away from the groove 25 extends through to the front of the interior of the U-shaped placement groove 23. The conveying component 2 includes a drive motor 21. The bottom center of the support base 1 has a connecting groove 11. The drive motor 21 is fixedly connected inside the connecting groove 11. The output shaft of the drive motor 21 extends through to the top of the support base 1 and is fixedly connected to the bottom center of the rotating table 22.

[0025] The overall effect achieved in Embodiment 1 is as follows: Before dispensing PC plastic granules, the operator opens the cover 5 of the storage hopper 4 and pours the PC plastic granules into the storage hopper 4. Then, the empty dispensing bucket is placed in the U-shaped placement groove 23 of the rotating table 22. Since the rollers 24 on the lower surface of the inner wall of the U-shaped placement groove 23 can greatly reduce the friction between the dispensing bucket and the bottom of the groove, the operator only needs to gently push to place the dispensing bucket smoothly into the appropriate position. Then, the rotating stop 26 is rotated out of the groove 25 to position it... A limit is set on the front side of the U-shaped placement trough 23 to prevent the dispensing barrel from shifting or slipping during subsequent dispensing. The drive motor 21 is started, and the output shaft of the drive motor 21 drives the rotating table 22 to rotate, so that the U-shaped placement trough 23 containing the dispensing barrels is rotated to the discharge port below the storage bin 4 in sequence, realizing the automatic conveying and positioning of the dispensing barrels, ensuring the continuity and efficiency of the dispensing process. At the same time, when one of the dispensing barrels is being filled, the operator can load and unload the already filled dispensing barrel, which greatly improves work efficiency.

[0026] Example 2: As shown in Figures 3 and 4, this utility model provides a technical solution: a discharge pipe 41 is fixedly connected to the bottom rear side of the storage silo 4, an extension pipe 42 is slidably connected to the outer surface of the discharge pipe 41, a drive motor 43 is fixedly connected to the bottom of the storage silo 4, a transmission screw 44 is fixedly connected to the output shaft of the drive motor 43, a threaded sliding column 45 is threadedly connected to the outer surface of the transmission screw 44, the threaded sliding column 45 is fixedly connected to the outer surface of the extension pipe 42, and a rotating column 4 is rotatably connected to the bottom of the inner surface of the discharge pipe 41. 11. A rotating baffle 412 is fixedly connected to the middle of the rotating column 411. A connecting groove 421 is provided on the front side of the inner surface of the extension tube 42. The front end of the rotating column 411 passes through the interior of the connecting groove 421 and is fixedly connected to the connecting slide plate 413. A sliding column 414 is fixedly connected to the left side of the front side of the connecting slide plate 413. A vertical groove 422 is provided on the left side of the inner wall of the connecting groove 421. The sliding column 414 is slidably connected to the interior of the vertical groove 422. An oblique groove 423 is provided at the top of the vertical groove 422.

[0027] The overall effect achieved in Embodiment 2 is as follows: After the rotating table 22 conveys the dispensing barrel to the discharge port below the storage silo 4, the drive motor 43 is started. The drive motor 43 drives the transmission screw 44 to rotate. Since the threaded sliding column 45 is threadedly connected to the transmission screw 44 and fixed on the extension tube 42, the threaded sliding column 45 will move vertically with the rotation of the transmission screw 44, thereby driving the extension tube 42 to slide down along the discharge tube 41. During the downward movement of the extension tube 42, the sliding column 414 on it slides in the vertical groove 422. When the sliding column 414 slides to the inclined groove 423 at the top of the vertical groove 422, as the extension tube 42 continues to slide down, the inclined groove 423... 3. This forces the sliding column 414 to rotate the connecting slide plate 413. The connecting slide plate 413, through the rotating column 411, drives the rotating baffle 412 to rotate, thereby opening the discharge pipe 41. PC plastic granules fall from the storage bin 4 through the discharge pipe 41 and the extension pipe 42 into the lower dispensing bucket. When the dispensing bucket is full, the drive motor 43 reverses, causing the extension pipe 42 to retract upwards. The sliding column 414 slides in the opposite direction along the inclined slide groove 423 and the vertical slide groove 422. The rotating baffle 412 resets synchronously, closing the discharge pipe 41 and completing one automatic filling and sealing operation. The entire process requires no manual intervention, effectively avoiding the problem of PC plastic granule splashing and leakage, and improving the accuracy and safety of dispensing.

[0028] The working principle of the whole equipment is as follows: Before the equipment is started, PC plastic granules are first loaded into the storage bin 4. The bin cover 5 is opened for filling. Then the bin cover is closed to prevent the granules from spilling. Next, the empty dispensing barrels are placed into the U-shaped placement groove 23 of the rotating table 22 in sequence. The rollers 24 are used to assist in placement and the rotating stop 26 is rotated to limit the position.

[0029] After the equipment is started, the drive motor 21 runs, driving the rotating table 22 to rotate, and rotates the first U-shaped placement trough 23 containing the dispensing barrel to the discharge port below the storage bin 4. At this time, the drive motor 43 starts, the drive screw 44 rotates, driving the extension tube 42 to slide down. Under the guidance of the vertical slide 422 and the inclined slide 423, the sliding column 414 causes the rotating baffle 412 to rotate and open the discharge pipe 41, and the PC plastic granules begin to fall into the dispensing barrel.

[0030] When the dispensing barrel is nearly full, the drive motor 43 reverses, the extension tube 42 retracts, the rotating baffle 412 resets and closes the discharge tube 41, stopping the feeding. At the same time, the drive motor 21 starts again, the rotating table 22 rotates, and the full dispensing barrel is rotated out. The next empty dispensing barrel is rotated to the discharge port, and the above filling process is repeated.

[0031] During the rotation of the rotating table 22, the operator can remove the filled dispensing bucket from the U-shaped placement groove 23, release the limit by rotating the rotating stop 26, use the roller 24 to assist in the removal, and put in a new empty dispensing bucket, so that the loading and unloading of buckets and dispensing are carried out simultaneously, and the automatic dispensing of PC plastic granules is completed continuously and efficiently.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
