[0002] Polypropylene, as an important thermoplastic resin, has been widely used in many fields such as packaging, automobiles, home appliances, and construction due to its excellent physical properties, chemical stability, and processing performance. In the production process of polypropylene granules, quality control is a key link to ensure that the products meet market standards and customer requirements. Sampling and testing, as one of the core means of quality control, can reflect the various performance indicators of polypropylene granules in a timely and accurate manner during the production process.

[0003] Current methods for sampling polypropylene granules in production typically involve manually using sampling tools to collect samples of the granules discharged from the production equipment and falling into the collection box at different times. However, the current method requires manual sampling with the sampling tools repeatedly at regular intervals, which is cumbersome, time-consuming, and labor-intensive. It is impossible to automatically and continuously sample polypropylene granules during production, making it difficult to guarantee production quality and seriously affecting sampling and production efficiency.

[0004] Therefore, it is necessary to design a sampling and material handling device for polypropylene particle production that can automatically sample polypropylene particles during production, achieve continuous sampling, be easy to operate, reduce manual intervention, ensure production quality, and improve sampling and production efficiency.

[0013] Beneficial effects: 1. This utility model feeds polypropylene granules into the feeding pipe. At the same time, the feeding pipe is opened by rotation, and some polypropylene granules will fall into the feeding pipe. The polypropylene granules are then conveyed by the rotating spiral conveyor blades and slide out from the feeding port into the sampling cylinder for sampling. The sampling cylinder is switched by rotating the rotating plate. Thus, it is possible to automatically sample polypropylene granules and achieve continuous sampling during production. The operation is simple, reduces manual intervention, ensures production quality, and improves sampling and production efficiency.

[0014] 2. In this invention, the rotating screw conveyor blade drives the pulley to rotate, which in turn drives the flat belt to rotate, thereby driving the rotating frame to rotate and compress the unblocking frame to move. When the rotating frame disengages from the unblocking frame, the unblocking frame moves in the opposite direction to reset. The unblocking frame then moves back and forth to unblock the discharge port, thus enabling the unblocking of the discharge port during sampling, preventing the discharge port from being blocked and affecting the sampling, and speeding up the sampling process.

[0022] A sampling and feeding device for polypropylene granule production, such as Figures 1-5 As shown, the system includes a feeding pipe 1, a storage frame 2, a shield 3, a conveying pipe 4, a feeding port 5, a first motor 6, a gear set 7, a second motor 8, a spiral conveyor blade 9, an anti-blocking component, and a collection component. The storage frame 2 is located to the right of the feeding pipe 1. The shield 3 is connected to the lower part of the feeding pipe 1, and the conveying pipe 4 is rotatably connected to the shield 3. The feeding port 5 is connected to the upper left side of the storage frame 2. The conveying pipe 4 is rotatably connected to the feeding port 5. The first motor 6 is connected to the upper side of the feeding port 5. The first motor 6 and the processor are electrically connected through a control module. The output shaft of the first motor 6 is connected to the conveying pipe 4. A gear set 7 is provided, which includes a gear and a gear ring. The output shaft of the first motor 6 is connected to the gear. The outer right side of the conveying pipe 4 is connected to the gear ring, and the gear and gear ring mesh with each other. The right side of the discharge port 5 is connected to the second motor 8. The second motor 8 and the processor are electrically connected through a control module. The middle of the conveying pipe 4 is rotatably connected to the spiral conveying blade 9, which is connected to the output shaft of the second motor 8. The discharge port 5 is provided with an anti-blocking component to prevent the conveying pipe 4 and the discharge port 5 from being blocked. The storage frame 2 is provided with a collection component for switching the collection of polypropylene particles.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the anti-blocking assembly includes a transmission assembly 10, a rotating frame 11, a clearing frame 12, and a telescopic spring 13. The rotating frame 11 is rotatably connected to the upper right of the discharge port 5. The transmission assembly 10 is provided between the rotating frame 11 and the spiral conveyor blade 9. The transmission assembly 10 includes a pulley and a flat belt. The rotating frame 11 and the right side of the spiral conveyor blade 9 are both connected to pulleys. A flat belt is wound between the pulleys. The clearing frame 12 is slidably connected to the upper part of the discharge port 5. The upper right part of the clearing frame 12 is triangular to facilitate compression. Two telescopic springs 13 are connected between the clearing frame 12 and the conveying pipe 4.

[0024] like Figure 1 , Figure 2 and Figure 5As shown, the collection assembly includes a third motor 14, a rotating plate 15, sampling tubes 16, a shielding plate 17, and torsion springs 18. The third motor 14 is connected to the middle of the storage frame 2. The third motor 14 and the processor are electrically connected through a control module. The rotating plate 15 is connected to the output shaft of the third motor 14. The rotating plate 15 is rotatably connected to the storage frame 2. Six sampling tubes 16 are snapped onto the rotating plate 15. The shielding plate 17 is rotatably connected to the upper part of the storage frame 2. A handle is provided on the upper right side of the shielding plate 17 for easy gripping and rotating to open the shielding plate 17. Two torsion springs 18 are connected between the shielding plate 17 and the storage frame 2.

[0025] This device can be used when sampling is required during polypropylene granule production. The feed pipe 1 is installed at the discharge port of the production equipment. The baffle 17 is opened by rotating the handle, causing the torsion spring 18 to deform. The sampling cylinder 16 is then engaged with the rotating plate 15. The processor then starts the third motor 14 via the control module, which drives the rotating plate 15 to rotate. The sampling cylinder 16 is then engaged with the rotating plate 15. After installation, the third motor 14 is turned off, and the sampling cylinder 16 is installed. The handle is then released, the torsion spring 18 rotates back to its original position, and the baffle 17 rotates to close. The polypropylene granules then flow into the feed pipe 1 for feeding. During feeding, the processor starts the first motor 6 via the control module, which drives the gear to rotate. The gear meshes with the gear ring, causing the conveying pipe 4 to rotate and open along the baffle 3. The first motor 6 is then turned off, and some polypropylene granules fall into the conveying pipe 4. Simultaneously, the second motor 8 is started, which drives the spiral conveyor blade 9 to transport the polypropylene granules. The process involves the polypropylene granules sliding into the feed inlet 5 and falling into the corresponding sampling cylinder 16 below the feed inlet 5 for sampling. After sampling, the second motor 8 is turned off, and the first motor 6 operates in reverse, causing the gear to rotate in the opposite direction. The gear meshes with the gear ring, causing the feed pipe 4 to rotate and close, thus continuing to feed polypropylene granules. After a period of time, the third motor 14 rotates, driving the rotating plate 15 to rotate, causing the next sampling cylinder 16 to rotate below the feed inlet 5. The above operation is then repeated to sample the polypropylene granules. The sampling cylinder 16 is then switched to sample polypropylene granules at different times, thus enabling automatic sampling of polypropylene granules during production while achieving continuous sampling. This method is simple to operate, reduces manual intervention, ensures production quality, and improves sampling and production efficiency. After sampling, the shielding plate 17 is rotated to open, the torsion spring 18 deforms, and the sampling cylinder 16 is then removed. A new sampling cylinder 16 is then engaged with the rotating plate 15 to continue sampling. After use, the first motor 6, the second motor 8, and the third motor 14 are turned off.

[0026] As the spiral conveyor blade 9 rotates, it drives the pulley to rotate, causing the flat belt to rotate, which in turn drives the rotating frame 11 to rotate and compress the unblocking frame 12 to move. The telescopic spring 13 is stretched. When the rotating frame 11 disengages from the unblocking frame 12, the telescopic spring 13 rebounds, and the unblocking frame 12 moves in the opposite direction to reset. The unblocking frame 12 then moves back and forth to unblock the discharge port 5. The upper right part of the unblocking frame 12 is triangular, which allows it to unblock the discharge port 5 during sampling, preventing the discharge port 5 from being blocked and affecting sampling, and speeding up the sampling process.
