Description

Technical Field

[0001] This utility model relates to the field of material tray transfer technology, specifically a material tray circulating transfer structure. Background Technology

[0002] Through systematic design and automation technology, the material tray circulation transfer system enables the efficient and orderly flow of material trays in the production or logistics process. Furthermore, automated transfer reduces the need for manual handling and lowers labor costs. In the existing material tray circulation transfer structure, the material tray will shift in position due to circulation transportation, which requires manual adjustment of the material tray and causes inconvenience in use; To address the aforementioned deficiencies, CN211520861U discloses a transfer device for a production line corner and a production line for the circulation transfer of material trays. These devices enable the switching and conveying of material trays between a first production line and a second production line, and ensure the conveying of the first production line when no reversing operation is performed. Specifically, the first and second production lines intersect. A first conveyor assembly is connected to the first production line and conveys trays along its direction. A second conveyor assembly extends upward from a notch in the first conveyor assembly and connects to the second production line, conveying trays from the first production line to the second production line, or vice versa. When the second conveyor assembly is below the first conveyor assembly, the conveying plane of the first conveyor assembly is flush with the conveying plane of the first production line, ensuring that trays on the first production line are continuously conveyed along its direction. When a tray from the second production line needs to be transferred to the first production line, or vice versa, the second conveyor assembly moves upward to extend from the notch in the first conveyor assembly and rests on the tray, completing the switching action of the tray between the two production lines. This has significant practical implications. In actual use, although the above device can avoid deviation, it requires the telescopic component to drive the clamping component to limit the material tray. This causes the material tray to rub against the inner wall of the clamping component, which leads to wear on the material tray and eventually damage to it, resulting in poor performance.

[0003] Therefore, we proposed a circulating transfer structure for material trays that can effectively solve the above problems. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: A circulating transfer structure for a material tray solves the problem that existing methods require a telescopic component to drive a clamping component to limit the material tray, which causes friction between the material tray and the inner wall of the clamping component. This friction leads to wear and eventual damage to the material tray, resulting in poor performance. The use of rollers 8 reduces wear on the material tray, thereby improving its service life. The following is disclosed: The right side of the first conveyor frame 1 is attached to the left side of the second conveyor frame 2; the bottom of the second conveyor frame 2 is fixed with a telescopic rod 3, and the top of the telescopic rod 3 is fixed with a conveyor belt 4, and the top of the conveyor belt 4 extends out of the interior of the second conveyor frame 2 to form a transfer mechanism; the top of the second conveyor frame 2 is fixed with a bracket 5, and the interior of the bracket 5 is rotatably connected to a threaded rod 6 through a bearing, and a limit plate 7 is threadedly connected to the threaded rod 6, and the bottom of the limit plate 7 is attached to the top of the second conveyor frame 2 to form a limit mechanism. The limit mechanism includes a roller 8, and the roller 8 is connected to the inner wall of the limit plate 7 through a bearing, and the roller 8 is made of rubber material. The threaded rod 6 is provided with two sets of threads, and the two sets of threads on the threaded rod 6 are arranged in opposite directions, and both sets of threads on the threaded rod 6 are connected to the limit plate 7. The top of the limit plate 7 extends into the interior of the bracket 5 to form a limit mechanism. refer to Figures 1 to 4 The first conveyor frame 1 can transport the material tray to the conveyor belt 4. Then, by retracting the telescopic rod 3, the telescopic rod 3 can drive the conveyor belt 4 to move, so that the conveyor belt 4 is lower than the height of the second conveyor frame 2, so that the material tray can contact the second conveyor frame 2, and the second conveyor frame 2 can drive the material tray to be transported. Thus, the material tray can be circulated and transferred. By rotating the threaded rod 6, the threaded rod 6 can drive the limiting plate 7 to slide on the bracket 5, so that the limiting plate 7 can drive the roller 8 to move. The movement of the roller 8 can make it fit against the surface of the material tray, so that the roller 8 will rub against the material tray, thus reducing the wear of the material tray.

[0017] Example 2: A circulating transfer structure for a material tray solves the problem of the need for manual cleaning of the material tray in existing systems. The use of nozzle 13 enables automated cleaning of the material tray, thereby improving ease of use. The following is disclosed: The rotating rod 12 is connected to the bracket 5 via a bearing, and the left end of the rotating rod 12 is fixed with a nozzle 13. The top of the nozzle 13 is connected to an external air pump via a hose. refer to Figure 1 , Figure 3 and Figure 4 An external air pump can deliver gas into the nozzle 13, which can then blow the gas onto the surface of the material tray. The material tray is in contact with the roller 8, thus preventing the gas from blowing the material tray off-center and preventing impurities from being contained in the material tray. This achieves the purpose of automated cleaning and improves the ease of use.

[0018] Example 3: A circulating transfer structure for a material tray solves the problem of the limited usable range of the nozzle 13 in Example 2. The usable range of the nozzle 13 can be increased by using the first gear 10. The following is disclosed: A motor 9 is fixed to the top of the bracket 5, and the output end of the motor 9 is keyed to the first gear 10. The first gear 10 has half of its teeth set and the other half is smooth. The bottom of the first gear 10 meshes with the second gear 11, and the middle part of the second gear 11 is keyed to the right side of the rotating rod 12 to form a transmission mechanism. A spiral spring 14 is nested on the left side of the rotating rod 12, and the left end of the spiral spring 14 is connected to the right side of the nozzle 13 to form a reset mechanism. The right end of the spiral spring 14 is connected to the bracket 5. refer to Figures 4 to 6 The motor 9 drives the first gear 10 to rotate, which in turn drives the second gear 11 to rotate. The second gear 11 then drives the rotating rod 12 to rotate, which in turn drives the nozzle 13 to swing. The rotation of the nozzle 13 compresses the spiral spring 14, causing it to be compressed. After the first gear 10 and the second gear 11 disengage, the force of the spiral spring 14 pushes the nozzle 13 to rotate in the opposite direction. This process repeats, allowing the nozzle 13 to swing back and forth, thus increasing the cleaning range of the nozzle 13.

[0019] Working principle: When using this type of cyclic transfer structure for material trays, firstly, refer to... Figures 1 to 4 The first conveyor frame 1 can transport the material tray to the conveyor belt 4. Then, by retracting the telescopic rod 3, the conveyor belt 4 can be lower than the height of the second conveyor frame 2, which in turn can drive the material tray to be transported. Thus, the material tray can be circulated and transferred. By rotating the threaded rod 6, the limiting plate 7 can drive the roller 8 to move, which will cause the roller 8 to rub against the material tray, thus reducing the wear on the material tray.

[0020] refer to Figure 1 , Figure 3 and Figure 4 An external air pump can deliver gas into the nozzle 13, which can then blow the gas onto the surface of the material tray. The material tray fits against the roller 8, thus preventing impurities from being contained within the tray and improving ease of use.

[0021] refer to Figures 4 to 6 The motor 9 drives the first gear 10 to rotate, which in turn drives the second gear 11 to rotate. This causes the rotating rod 12 to drive the nozzle 13 to swing. After the first gear 10 and the second gear 11 disengage, the force of the spiral spring 14 can push the nozzle 13 to rotate in the opposite direction. This process is repeated, thus increasing the cleaning range of the nozzle 13.
