[0002] Polyester film, due to its excellent comprehensive properties, is widely used in industries such as electrical, electronics, optoelectronics, new energy, and outdoor advertising. To ensure the functionality of polyester film, the production formula of polyester film is becoming increasingly complex, and the types of functional masterbatches required are gradually increasing. The transportation of various raw materials in film production is becoming increasingly important. Ensuring timely switching of various raw materials during production to avoid mixing, while also ensuring production stability, has become a problem that must be addressed. Currently, the common method in the industry is as follows: materials are transported from storage silos to various target silos through pneumatic pipelines. The direction of material flow to a silo is determined by opening the directional valves at the top of each silo, which are connected to the pipeline. The directional valves are driven by compressed air, and the pressure fluctuations and cleanliness of the compressed air affect the reliability of the directional valves. The multiple branches of the conveying pipeline make polyester chips prone to breakage during transportation, affecting the quality of the final product. Therefore, a material conveying device that can connect to each silo is needed to reduce the breakage of polyester chips and improve the reliability of polyester chip transportation.

[0012] See Figure 1 and Figure 2 This utility model includes an unloading section, a guiding section, and a traction section. Both the guiding section and the traction section are mounted on the top surface of the hopper via brackets, and the traction section is connected to the guiding section. The unloading section includes an upper spherical conveying mechanism, a telescopic mechanism, and a lower spherical conveying mechanism. The telescopic mechanism is located between the upper and lower spherical conveying mechanisms. When the distance between the upper and lower spherical conveying mechanisms changes, the telescopic mechanism ensures a normal connection between the channels, ensuring that materials are smoothly conveyed from the upper spherical conveying mechanism to the lower spherical conveying mechanism. The upper spherical conveying mechanism is connected to a pneumatic conveying pipeline, and the lower spherical conveying mechanism is connected to the guiding section. The guiding section and the traction section work together to adjust the position of the lower spherical conveying mechanism, thereby adjusting the position of the material end point to ensure alignment with the feed hole at the top of the target hopper.
[0013] The upper spherical conveying mechanism includes an upper inner sphere 1 and an upper outer sphere 2. The upper inner sphere 1 has openings at both opposite ends, with the first opening connected to a pneumatic conveying pipeline via a branch pipe. The upper inner sphere 1 is located inside the upper outer sphere 2, and the second opening of the upper inner sphere 1 is located inside the upper outer sphere 2. The upper inner sphere 1 rotates inside the upper outer sphere 2. Since the position of the upper inner sphere 1 remains constant, while the position of the lower outer sphere 6 is adjusted according to the position of the hopper, the distance between the upper and lower spherical conveying mechanisms will change. When the distance changes... The telescopic mechanism adapts to lengthen or shorten, ensuring smooth material transfer between the two conveying mechanisms. When the position of the outer sphere 6 changes, the upper outer sphere 2 and the lower inner sphere 5 adapt to rotate, thereby ensuring that the combination of the straight cylinder 3 and the sleeve 4 can smoothly connect the upper inner sphere 1 and the lower outer sphere 6. The outer wall of the upper inner sphere 1 is in close contact with the inner wall of the upper outer sphere 2. The upper outer sphere 2 has openings at opposite ends, and the outer wall of the upper inner sphere 1 partially extends from the first opening of the upper outer sphere 2. The second opening of the upper outer sphere 2 is connected to the top of the telescopic mechanism.
[0014] The telescopic mechanism includes a straight cylinder 3 and a sleeve 4; the top end of the straight cylinder 3 is connected to the second opening of the upper outer sphere 2; the inner wall of the sleeve 4 is slidably fitted onto the outer wall of the straight cylinder 3; the axis of the straight cylinder 3 coincides with the axis of the sleeve 4; the total length is adjusted by the relative sliding between the straight cylinder 3 and the sleeve 4; thereby adapting to the change in distance between the upper inner sphere 1 and the lower outer sphere 6, and smoothly connecting the channel between the upper inner sphere 1 and the lower outer sphere 6.
[0015] The lower spherical conveying mechanism includes a lower inner sphere 5 and a lower outer sphere 6. The principle of the upper spherical conveying mechanism is the same as that of the lower spherical conveying mechanism. Both can ensure smooth connection between the upper and lower spherical conveying mechanisms by rotating and adjusting the angle. The lower inner sphere 5 has openings at both opposite ends, and the first opening is in contact with the bottom end of the sleeve 4. The lower inner sphere 5 is located inside the lower outer sphere 6, and the second opening of the lower inner sphere 5 is located inside the lower outer sphere 6. The outer wall of the lower inner sphere 5 is in close contact with the inner wall of the lower outer sphere 6. The lower outer sphere 6 has openings at both opposite ends, and the outer wall of the lower inner sphere 5 partially protrudes from the first opening of the lower outer sphere 6, while the second opening of the lower outer sphere 6 contacts the guide portion.
[0016] The guiding section includes a guide bar 7, a round rod 8, a connecting rod 9, a horizontal plate 10, and a discharge cylinder 11. The two ends of the guide bar 7 are mounted on the top surface of the hopper via brackets, and the guide bar 7 passes sequentially through the feed inlets at the top of each hopper. The round rod 8 moves along the trajectory of the guide bar under the guidance of the guide bar 7, thus driving the lower outer ball 6 on the horizontal plate 10 to move synchronously. This ultimately achieves the goal of driving the lower outer ball 6 sequentially past the feed inlets at the top of each hopper. After determining the target hopper, it is only necessary to control the lower outer ball 6... Unloading can be performed by stopping directly above the loading hole at the top of the target silo; the center of the guide strip 7 is provided with a guide hole along its trajectory, and the round rod 8 is inserted into the guide hole of the guide strip 7; the top surface of the round rod 8 is provided with a connecting rod 9, and the horizontal plate 10 is connected to the connecting rod 9; the center of the horizontal plate 10 is provided with a hole, and the second opening of the lower outer sphere 6 is connected to the hole on the top surface of the horizontal plate 10, and the unloading cylinder 11 is connected to the hole on the bottom surface of the horizontal plate 10; the unloading cylinder 11 ensures that the material is more accurately put into the loading hole at the top of the silo.
[0017] The traction part includes an insert plate 12, a guide plate 13, a support plate 14, and a servo motor 15. The support plate 14 is disposed on the top surface of the hopper, and the servo motor 15 is disposed on the support plate 14. The output shaft of the servo motor 15 is connected to one end of the bottom surface of the guide plate 13. The servo motor can drive the guide plate 13 to rotate. The end of the guide plate 13 away from the servo motor 15 is provided with a guide hole, and the insert plate 12 is inserted into the guide hole of the guide plate 13. The end of the insert plate 12 away from the guide plate 13 is connected to the outer ring of the bearing, and the inner wall of the inner ring of the bearing is connected to the bottom end of the outer wall of the round rod 8. The rotation of the output shaft of the servo motor 15 drives the guide plate 13 to flip, and the guide plate 13 drives the insert plate 12 to flip synchronously. Since the end of the insert plate is connected to the round rod 8, the flipped insert plate can drive the round rod 8 to move along the guide bar 7. When the distance between the round rod 8 and the servo motor changes, it is adapted by the change in the total length of the combination of the insert plate 12 and the guide plate 13. Since the rotation angle of the servo motor is fixed when the unloading cylinder is directly above the top loading hole of each hopper, when the unloading cylinder needs to be moved above the loading hole of a designated hopper, the servo motor only needs to rotate to the specific angle corresponding to this hopper.
[0018] Operating principle: When it is necessary to load material into the hopper, after the hopper is determined, the servo motor is activated. The output shaft of the servo motor rotates at a specified angle, causing the round rod 8 to move the unloading cylinder 11 to the designated position directly above the loading hole of the hopper. During this process, the upper outer ball 2 and the upper inner ball 5 rotate adaptively, and the straight cylinder 3 is stretched, ensuring the connection between the pneumatic pipeline and the unloading cylinder 11. After the unloading cylinder 11 is in place, the conveying function of the pneumatic pipeline is activated, and material conveying begins. The material passes sequentially from the end of the pneumatic pipeline through the upper inner ball, the upper outer ball, the straight cylinder, the sleeve, the lower inner ball, the lower outer ball, and the unloading cylinder before entering the loading hole of the hopper.
