[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a stabilizer rod resistance heating automatic feeding trolley, including a bracket 1, a pulley 2 fixedly connected to the lower surface of the bracket 1, an mounting plate 3 fixedly connected to the lower surface of the bracket 1, a conveying mechanism 4 provided on the upper surface of the bracket 1, a feeding mechanism 5 provided on the upper surface of the bracket 1, and material 6 provided on the upper surface of the feeding mechanism 5.

[0021] The conveying mechanism 4 includes a motor 401, a transmission wheel 402, a transmission belt 403, a rotating wheel 404, a first rotating shaft 405, a transmission gear 406, a conveying chain 407, a first stabilizing block 408, a limiting block 409, a support plate 410, a rotating gear 411, a support rod 412, a limiting block 413, a second stabilizing block 414, a second rotating shaft 415, a second transmission gear 416, a fixing rod 417, a fixing plate 418, a limiting plate 419, and a limiting groove 420. The motor 401 is fixedly connected to the upper surface of the mounting plate 3. A transmission wheel 402 is fixedly connected to one end of the motor 401. A transmission belt 403 is attached to the outer surface of the transmission wheel 402, and a rotating wheel 404 is attached to the inner surface of the transmission belt 403. A first rotating shaft 405 is fixedly connected to the inner surface of the drive wheel 404. A transmission gear 406 is fixedly connected to the outer surface of the first rotating shaft 405. A transmission chain 407 meshes with the outer surface of the transmission gear 406. A first stabilizing block 408 is rotatably connected to the outer surface of the first rotating shaft 405. A limit block 409 is fixedly connected to one end surface of the first stabilizing block 408. A support plate 410 is fixedly connected to the upper surface of the bracket 1. A rotating gear 411 is mounted on the upper surface of the support plate 410. A support rod 412 is fixedly connected to the upper surface of the support plate 410. A limit block 413 is fixedly connected to the upper surface of the support rod 412. A second stabilizing block 414 is fixedly connected to the upper surface of the bracket 1. The inner surface of the second stabilizing block 414 rotates... A second rotating shaft 415 is connected, and a second transmission gear 416 is fixedly connected to the outer surface of the second rotating shaft 415. A fixing rod 417 is fixedly connected to the upper surface of the bracket 1, and a fixing plate 418 is fixedly connected to the upper surface of the fixing rod 417. A limit plate 419 is fixedly connected to the upper surface of the fixing plate 418, and a limit groove 420 is formed on the inner surface of the limit plate 419. The system is connected via a motor 401, a transmission wheel 402, a transmission belt 403, a rotating wheel 404, a first rotating shaft 405, a transmission gear 406, a transmission chain 407, a first stabilizing block 408, a limit block 409, a support plate 410, a rotating gear 411, a support rod 412, a limit block 413, a second stabilizing block 414, a second rotating shaft 415, and a second transmission gear. The installation of components 416, 417, 418, 419, and 420 allows for the following operation: When the motor 401 is started, its rotation drives the transmission wheel 402 to rotate. This rotation, through friction, drives the transmission belt 403, which in turn drives the rotating wheel 404. The rotating wheel 404 then drives the first shaft 405 to rotate synchronously. As the first shaft 405 rotates, the transmission gear 406 rotates accordingly. A transmission chain 407 meshes with the outer surface of the transmission gear 406. The rotation of the transmission gear 406, through gear meshing, moves the transmission chain 407. Because the transmission chain 407 is a ring structure, it can rotate continuously.This enables the material 6 to be transferred on the conveyor chain 407. The first stabilizing block 408 supports the rotation of the first rotating shaft 405. A rotating gear 411 is mounted on the upper surface of the support plate 410. Four sets of rotating gears 411 assist the rotation of four sets of conveyor chains 407. The conveyor chains 407 slide through the groove inside the limiting block 413 on the upper surface of the support rod 412. The second rotating shaft 415 rotates flexibly within the second stabilizing block 414. A second transmission gear 416 is fixedly connected to the outer surface of the second rotating shaft 415, further assisting the transmission of the conveyor chain 407 and tensioning the conveyor chain 407 to ensure its normal operation. The conveyor chain 407 slides smoothly within the limiting groove 420 on the inner surface of the limiting plate 419. The conveying mechanism 4 can stably and reliably achieve the task of transferring material 6.

[0022] Furthermore, the conveyor chain 407 is provided with four sets, and the first stabilizing block 408 is provided with two sets on the outer surface of the first rotating shaft 405. Through the arrangement of the conveyor chain 407, in use, multiple sets of conveyor chains 407 can support and limit the material 6 from multiple positions, and can disperse the gravity of the material 6, so that the load borne by each chain is relatively reduced, making the conveying of the material 6 more stable.

[0023] Furthermore, two sets of limiting blocks 409 are provided at both ends of the first rotating shaft 405, and four sets of rotating gears 411 are provided on the upper surface of the support plate 410. Through the setting of the limiting blocks 409, during use, the limiting blocks 409 mainly play the role of axial positioning, ensuring the stability of the position of the first rotating shaft 405, and can assist the first rotating shaft 405 to rotate stably. Since they are located at both ends of the first rotating shaft 405, they can balance the force on the first rotating shaft 405 to a certain extent and reduce the shaft swing caused by uneven force.

[0024] Furthermore, the inner dimensions of the limiting block 413 match the outer dimensions of the transmission chain 407. Four sets of second transmission gears 416 are provided on the outer surface of the second rotating shaft 415. With the setting of the limiting block 413 and the transmission chain 407, the transmission chain 407 slides inside the limiting block 413 during use. The limiting block 413 limits and guides the transmission chain 407, making the movement of the transmission chain 407 more stable.

[0025] Furthermore, two sets of limiting blocks 409 are provided at both ends of the second rotating shaft 415, and four sets of limiting grooves 420 are provided on the inner surface of the limiting plate 419. Through the setting of the limiting grooves 420 and the limiting plate 419, the limiting grooves 420 limit the conveyor chain 407 during use. The four sets of limiting grooves 420 can constrain the conveyor chain 407 from different positions, so that the conveyor chain 407 can only move within the path defined by the limiting grooves 420, thus maintaining the stability of power transmission.

[0026] Furthermore, the feeding mechanism 5 includes a stabilizing side plate 501, a rotating shaft 502, a rotating feeding rod 503, a connecting rod 504, and a cylinder 505. The stabilizing side plate 501 is fixedly connected to the upper surface of the support 1. The rotating shaft 502 is rotatably connected to the inner surface of the stabilizing side plate 501. The rotating feeding rod 503 is fixedly connected to the outer surface of the rotating shaft 502. A connecting rod 504 is fixedly connected to one end of the rotating feeding rod 503. A cylinder 505 is fixedly connected to the lower surface of the connecting rod 504. Through the arrangement of the stabilizing side plate 501, rotating shaft 502, rotating feeding rod 503, connecting rod 504, and cylinder 505, during use, the mechanism is activated... When cylinder 505 pushes connecting rod 504 to move, since connecting rod 504 is fixedly connected to rotating feeding rod 503, rotating feeding rod 503 will rotate around rotating shaft 502. During the rotation, rotating feeding rod 503 will push material 6 to perform feeding operation, transferring material 6 from rotating feeding rod 503 to conveyor chain 407. When continuous feeding is required, cylinder 505 can repeatedly extend and retract according to the set program or operation requirements, thereby driving rotating feeding rod 503 to perform periodic rotation, continuously feeding material 6 into conveyor mechanism 4 to ensure continuous feeding of material 6.

[0027] Furthermore, the cylinder 505 is fixedly connected to the bracket 1, and two sets of rotating feeding rods 503 are provided on the outer surface of the connecting rod 504. The two sets of rotating feeding rods 503 are fixedly connected through the connecting rod 504. With the setting of the rotating feeding rods 503, in use, the two sets of rotating feeding rods 503 can work together through the fixed connection of the connecting rod 504. When the cylinder 505 pushes the connecting rod 504 to move, the two sets of rotating feeding rods 503 will be driven to rotate simultaneously. This synergistic effect can increase the efficiency and stability of feeding, and can better ensure the balance and directional accuracy of the material 6 during the pushing process than a single lever.

[0028] Working principle: When cylinder 505 is started, it pushes connecting rod 504 to move. Since connecting rod 504 is fixedly connected to rotating feeding rod 503, rotating feeding rod 503 will rotate around rotating shaft 502. During rotation, rotating feeding rod 503 will push material 6 to feed, transferring material 6 from rotating feeding rod 503 to conveyor chain 407. Motor 401 is started, and the rotation of motor 401 drives transmission wheel 402 to rotate together. When transmission wheel 402 rotates, it drives transmission belt 403 to rotate through friction. The rotation of transmission belt 403 drives rotating wheel 404 to rotate. The rotation of rotating wheel 404 drives first rotating shaft 405 to rotate synchronously. When first rotating shaft 405 rotates, transmission gear 406 rotates accordingly. The outer surface of transmission gear 406 meshes with conveyor chain 407. The rotation of transmission gear 406 drives conveyor chain through gear meshing. 407 moves. Since the conveyor chain 407 has a ring structure, it can rotate continuously, thereby realizing the function of material 6 being transferred on the conveyor chain 407. The first stabilizing block 408 supports the rotation of the first rotating shaft 405. The upper surface of the support plate 410 is equipped with rotating gears 411. The four sets of rotating gears 411 assist the rotation of the four sets of conveyor chains 407. The conveyor chain 407 slides through the groove inside the limiting block 413 on the upper surface of the support rod 412. The second rotating shaft 415 rotates flexibly in the second stabilizing block 414. The outer surface of the second rotating shaft 415 is fixedly connected to the second transmission gear 416, which further assists the transmission of the conveyor chain 407 and tensions the conveyor chain 407 to ensure the normal operation of the conveyor chain 407. The conveyor chain 407 slides smoothly in the limiting groove 420 opened on the inner surface of the limiting plate 419. The conveying mechanism 4 can stably and reliably realize the task of transferring material 6.
