In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0022] Please see Figures 1-5 This utility model provides an embodiment of a desiccant feeding device, including a support 1, a rotating shaft 2 rotatably connected to the surface of the support 1, a feeding tray 3 fixedly connected to the top of the rotating shaft 2, multiple sets of discharge ports 4 opened on the bottom wall of the inner cavity of the feeding tray 3, a support rod 5 fixedly connected to the surface of the support 1, a brush 6 fixedly connected to one end of the support rod 5, the brush 6 being located inside the feeding tray 3, and the lower surface of the brush 6 abutting against the bottom wall of the inner cavity of the feeding tray 3, a transmission rod 13 rotatably connected to the inner side wall of the support 1, a first bevel gear 14 fixedly connected to one end of the transmission rod 13, a second bevel gear 15 fixedly connected to one end of the rotating shaft 2, the second bevel gear 15 meshing with the first bevel gear 14, a drive motor 16 fixedly connected to the side wall of the support 1, the power output end of the drive motor 16 fixedly connected to the shaft end of the transmission rod 13; during operation, the drive motor 16 starts, its power output end drives the transmission rod 13 to rotate, and the first bevel gear 14 at one end of the transmission rod 13 rotates accordingly. The first bevel gear 14 meshes with the second bevel gear 15 at one end of the rotating shaft 2, thereby transmitting power to the rotating shaft 2. This causes the rotating shaft 2 to drive the feeding tray 3 to rotate. The desiccant in the feeding tray 3 diffuses to the surroundings under the action of centrifugal force. The brush 6 located in the feeding tray 3 has its lower surface in contact with the bottom wall of the inner cavity of the feeding tray 3, which can comb and push the desiccant, allowing it to be discharged smoothly through the discharge port 4. The bevel gear transmission, i.e., the meshing transmission of the first bevel gear 14 and the second bevel gear 15, can achieve a large angle of power transmission in a small space. The transmission is smooth and reliable, ensuring the stable rotation of the feeding tray 3 and improving the overall stability of the device. The brush 6 combs and pushes the desiccant during the feeding process, which can effectively prevent the desiccant from accumulating and blocking at the discharge port 4, so that the desiccant is discharged evenly and stably from the discharge port 4, ensuring the uniformity of feeding, and thus improving the quality and stability of subsequent production and processing.
[0023] In this embodiment, a bolt rod 7 is threadedly connected to the lower surface of the feeding tray 3. A cover plate 8 for closing the discharge port 4 is rotatably connected to the feeding tray 3 via the bolt rod 7. A spring 9 is directly mounted on the cover plate 8 and the bolt rod 7, and is sleeved on the bolt rod 7. A column 10 is fixedly connected to the surface of the support 1. A lever 11 is rotatably connected to the top of the column 10. An abutment 12 is fixedly connected to the surface of the lever 11, and the abutment 12 abuts against the side wall of the cover plate 8 when it rotates. The bolt rod 7 on the lower surface of the feeding tray 3 is connected to the cover plate 8, and the spring 9 is sleeved on the bolt rod 7. In its natural state, the spring 9 tends to close the discharge port 4 on the cover plate 8. When the lever 11 rotates with the top of the column 10... The abutment 12 on its surface rotates and abuts against the side wall of the cover plate 8, overcoming the elastic force of the spring 9, and lifts the cover plate 8 to open the discharge port 4, realizing the quantitative discharge of desiccant. The feeding tray 3 is connected to the cover plate 8 by bolt rod 7, which is convenient for disassembly and installation. When it is necessary to adjust the size of the discharge port 4 or to clean or maintain the device, the operation can be carried out quickly, improving the maintainability and flexibility of the equipment. Through the cooperation of the lever 11, the abutment 12, the cover plate 8 and the spring 9, the opening and closing of the discharge port 4 can be controlled, the discharge amount of desiccant can be precisely controlled, the quantitative feeding can be achieved, the precise requirements of different production processes for the amount of desiccant used can be met, the waste of raw materials can be reduced, and the production cost can be reduced.
[0024] During operation, the drive motor 16 starts, and its power output end drives the transmission rod 13 to rotate. The first bevel gear 14 at one end of the transmission rod 13 rotates accordingly. Since the first bevel gear 14 meshes with the second bevel gear 15 at one end of the rotating shaft 2, the power is transmitted to the rotating shaft 2, causing the rotating shaft 2 to drive the feeding tray 3 to rotate. The desiccant in the feeding tray 3 diffuses to the surroundings under the action of centrifugal force. The brush 6 located in the feeding tray 3 has its lower surface abutting against the bottom wall of the inner cavity of the feeding tray 3, which can comb and push the desiccant, so that the desiccant can be discharged smoothly through the discharge port 4. The bolt rod 7 on the lower surface of the feeding tray 3 is connected to the cover plate 8. The spring 9 is sleeved on the bolt rod 7. In the natural state, the spring 9 makes the cover plate 8 tend to close the discharge port 4. When the paddle 11 rotates with the top of the column 10, the abutment 12 on its surface rotates and abuts against the side wall of the cover plate 8, overcoming the elastic force of the spring 9, lifting the cover plate 8, opening the discharge port 4, and realizing the quantitative discharge of desiccant.
[0025] The device employs bevel gear transmission, specifically the meshing of the first bevel gear 14 and the second bevel gear 15. This enables power transmission at a large angle within a relatively small space, ensuring smooth and reliable transmission and guaranteeing the stable rotation of the feeding disc 3. This enhances the overall stability of the device's operation. The brush 6 combs and pushes the desiccant during the feeding process, effectively preventing its accumulation and blockage at the outlet 4. This ensures the desiccant is discharged evenly and stably from the outlet 4, guaranteeing uniform feeding and improving the quality and stability of subsequent production processes. The feeding disc 3 and the cover plate 8 are connected by bolt rods 7, facilitating disassembly and installation. When it is necessary to adjust the size of the outlet 4 or to clean or maintain the device, quick operations can be performed, improving the maintainability and flexibility of the equipment. The opening and closing of the outlet 4 can be controlled through the cooperation of the lever 11, the abutment joint 12, the cover plate 8, and the spring 9, precisely controlling the amount of desiccant discharged. This achieves quantitative feeding, meeting the precise requirements of different production processes for desiccant dosage, reducing raw material waste, and lowering production costs.
[0026] This specification describes the embodiments, but not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
