[0015] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail as follows: like Figures 1-3As shown, this embodiment discloses a steaming tray loading device, including an overall frame 1, a lifting device 2, and a floating loading section 3. The floating loading section 3 is movably connected to the overall frame 1 through the lifting device 2. The lifting device 2 includes a lifting motor 21, a driven gear 24, a large sprocket 25, and an intermediate transmission chain 26, as well as two sets of lifting transmission mechanisms 29 symmetrically arranged on the left and right sides of the overall frame 1. The output shaft of the lifting motor 21 is provided with a motor gear 22 and a motor sprocket 23. The driven gear 24 meshes with the motor gear 22 for transmission, and the driven gear 24 is rotatably connected to the overall frame 1 through a left transmission shaft 27. The large sprocket 25 is rotatably connected to the overall frame 1 through a right transmission shaft 28. The intermediate transmission chain 26 is hung between the motor sprocket 23 and the large sprocket 25. The input end of one set of lifting transmission mechanisms 29 is set on the left transmission shaft 27, and the input end of the other set of lifting transmission mechanisms 29 is set on the right transmission shaft 28.

[0016] like Figure 1 as well as Figure 4 As shown, the lifting transmission mechanism 29 includes a lifting drive sprocket 291, a lifting driven shaft 292, a lifting driven sprocket 293, and a lifting chain 294. A lifting driven shaft 292 is fixedly installed on each of the left and right sides below the overall frame 1. The lifting driven sprocket 293 is rotatably connected to the lifting driven shaft 292 via bearings. The lifting chain 294 is hung between the lifting drive sprocket 291 and the lifting driven sprocket 293. A chain connecting plate 295 is fixedly connected to the lifting chain 294, and the chain connecting plate 295 is fixedly connected to both sides of the floating loading section 3 via fastening bolts. Guide rails 11 are symmetrically laid on the overall frame 1, and the floating loading section 3 slides along the guide rails 11 on both sides via sliders. When the lifting motor 21 is started, the lifting chains 294 on the left and right sides of the overall frame 1 are synchronously driven.

[0017] like Figures 5-7As shown, the floating loading section 3 includes a loading frame 31, and two sets of feeding mechanisms 32 and two sets of pusher mechanisms 33 arranged symmetrically to the left and right of the loading frame 31. The loading frame 31 is fixedly connected to the slider through a chain connecting plate 295. The loading frame 31 is equipped with a feeding control motor 321 and a pusher control motor 331 at the front and rear respectively. The output shaft of the feeding control motor 321 is driven to connect to the feeding mechanism 32 through the feeding drive shaft 322. The pusher control motor 331 is driven to connect to the pusher mechanism 33 through the pusher drive shaft 332. The feeding mechanism 32 includes an active synchronizing pulley 323, a passive synchronizing pulley 324, and a timing belt 325. The feeding active shaft 322 is equipped with two active synchronizing pulleys 323 and two pusher passive sprockets 334. One end of the feeding active shaft 322 is fixedly connected to the output shaft of the feeding control motor 321 through a coupling, and the other end is rotatably connected to the loading frame 31 through a bearing seat. The active synchronizing pulleys 323 are fixedly mounted on the outer ring of the feeding active shaft 322. The passive synchronizing pulleys 324 are rotatably connected to the pusher active shaft 332 through bearings. The timing belt 325 is hung between the active synchronizing pulleys 323 and the passive synchronizing pulleys 324.

[0018] like Figures 5-7 As shown, the pusher mechanism 33 includes a pusher drive sprocket 333, a pusher driven sprocket 334, and a pusher chain 335. The pusher drive shaft 332 is equipped with two pusher drive sprockets 333 and two driven synchronous pulleys 324. One end of the pusher drive shaft 332 is fixedly connected to the output shaft of the pusher control motor 331 via a coupling, and the other end is rotatably connected to the loading frame 31 via a bearing seat. The pusher drive sprockets 333 are fixedly mounted on the outer ring of the pusher drive shaft 332. The pusher driven sprockets 334 are rotatably connected to the feed drive shaft 322 via bearings. The pusher chain 335 is hung between the pusher drive sprockets 333 and the pusher driven sprockets 334. The loading frame 31 is symmetrically welded with clamping plates 311. The pusher chain 335 is flexibly connected to clamping claws 336 via torsion springs. The clamping claws 336 are clamped below the clamping plates 311 by torsion springs. The vertical height of the pusher chain 335 is lower than that of the timing belt 325, and the vertical height of the timing belt 325 is lower than that of the chuck 336. Furthermore, the transmission between the timing belt 325 and the pusher chain 335 does not affect each other.

[0019] The working principle of the steaming tray loading device of this utility model is as follows: Upon power-on, the electrical control unit controls the lifting motor 21 to raise and lower the floating loading section 3, locates the origin sensor, and returns to the waiting position. The output shaft of the lifting motor 21 drives the coaxially mounted motor gear 22 and motor sprocket 23 to rotate simultaneously. The motor gear 22 meshes with the driven gear 24, transmitting power to the left drive shaft 27 to drive the lifting transmission mechanism 29 on the left side of the overall frame 1. Simultaneously, the rotation of the motor sprocket 23 drives the large sprocket 25 to rotate via the intermediate transmission chain 26, transmitting power to the right drive shaft 28 to drive the lifting transmission mechanism 29 on the right side of the overall frame 1. During the synchronous rotation of the lifting chains 294 on both sides, the loading frame 31 moves synchronously with the lifting chains 294 via the chain connecting plate 295.

[0020] The feeding control motor 321 is started, and the synchronous belt 325 rotates to begin conveying the steaming tray filled with steamed buns from the previous process. When the steaming tray is conveyed to the position of sensor 4 by the synchronous belt 325, the electrical control unit cuts off the power to the feeding control motor 321, and the synchronous belt 325 stops conveying. The pusher control motor 331 is started, and the pusher chain 335 rotates. At the same time, the chuck 336 moves and is ejected from under the chuck plate 311 by the action of the torsion spring. The chuck 336 pushes the steaming tray toward the steaming cart 7. When sensor 5 detects the passage of the steaming tray and counts it, the electrical control unit cuts off the power to the pusher control motor 331, and the pusher chain 335 stops conveying. At this time, the steaming tray is just pushed into the steaming cart 7.

[0021] After loading is complete, the pusher control motor 331 drives the pusher chain 335 to reverse, and the chuck 336 moves in the opposite direction with the pusher chain 335 until the chuck 336 retracts to the position of the pallet 311. Under the elastic deformation of the torsion spring, it is forced to engage under the pallet 311. At this time, the sensor 36 detects the chuck 336, and the electrical control unit stops the pusher control motor 331. Simultaneously, the lifting device 2 drives the floating loading part 3 back to its original position to prepare for the next loading. After loading each layer twice, the above actions are repeated to continue the loading work of the next layer. The parameterized control of the electrical control unit in this embodiment is prior art and will not be described in detail here.

[0022] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
