Description

Technical Field

[0001] This utility model relates to the field of food machinery technology, specifically a high-efficiency unloading machine. Background Technology

[0002] Baking, also known as roasting or baking, refers to the process of dehydrating, drying, and hardening materials by applying dry heat below their ignition point. Baking is an indispensable step in the production of bread and cakes. Through baking, starch gelatinizes, proteins denature, and undergo a series of chemical changes, achieving the desired maturity and altering the texture of the food. Generally, after kneading and shaping, bread or cakes are first placed on baking trays on a baking rack for fermentation before being baked in a tunnel oven. To save space, the baking racks are multi-layered. Moving the trays from the rack into the tunnel oven requires workers to frequently switch positions, resulting in high labor intensity. Furthermore, due to the numerous layers and large vertical span of the racks, manual handling leads to low production efficiency, and removing trays from higher layers also poses certain safety hazards.

[0021] 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.

[0022] like Figures 1 to 5 As shown, a high-efficiency plate-removing machine is characterized by comprising a frame 1, a housing frame 2, a support frame 3, a plate-transferring assembly 4, a first conveying assembly 5, a second conveying assembly 6, and a pushing mechanism 7. The housing frame is installed inside the frame 1, the housing frame 2 is connected to one end of the support frame 3, and the pushing mechanism 7 is installed at the other end of the housing frame 2. The housing frame 2 is used to place a cooking rack 8, and the pushing mechanism 7 is used to push the cooking plate on the cooking rack 8 onto the support frame 3. The plate-transferring assembly 4 is vertically and vertically installed inside the support frame 3. One end of the first conveying assembly 5 is rotatably connected to a motion assembly, and the other end is movably connected to the second conveying assembly 6. The first conveying assembly 5 can rotate synchronously with the lifting and lowering of the plate-transferring assembly 4. The plate-transferring assembly 4 contacts the bottom surface of the cooking plate on the support frame 3, thereby transporting the cooking plate from the support frame 3 to the first conveying assembly 5, and then to the second conveying assembly 6.

[0023] In this embodiment, the pushing mechanism 7 includes a support frame 9, a first motor 10, a pushing frame 11, a first drive frame 12, and a second drive frame 13. The support frame 9 is mounted on the right end of the receiving frame 2. One end of the first drive frame 12 is rotatably mounted on the upper left side of the support frame 9. A slide 14 is provided at the lower right end of the pushing frame 11. The other end of the first drive frame 12 is slidably mounted in the slide 14. One end of the second drive frame 13 is rotatably mounted on the upper right side of the pushing frame 11. The other end of the second drive frame 13 is slidably mounted on the lower left side of the support frame 9. The middle ends of the first drive frame 12 and the second drive frame 13 are rotatably connected. The first motor 10 is fixedly mounted on the support frame 9, and a drive block 15 is connected to its output shaft. The other end of the drive block 15 is rotatably connected to a connecting rod 16, and the other end of the connecting rod 16 is rotatably connected to the first drive frame 12.

[0024] In this embodiment, the front side of the accommodating rack 2 has an opening for the cooking rack 8 to enter and exit. Both the left and right ends of the front side of the opening are provided with baffles 17. The baffles 17 are rotatably mounted on the accommodating rack 2. Both the left and right ends of the accommodating rack 2 are hinged with cylinders 18. The piston rod of the cylinder 18 is hinged to the baffle 17 on the corresponding side, thereby driving the baffle 17 to rotate. Several limiting members 19 are provided at the rear end of the accommodating rack 2.

[0025] In this embodiment, several support plates 20 corresponding to the cooking rack 8 are provided on both the front and rear sides of the support frame 3, and several guide plates 21 corresponding to the support plates 20 are provided on both the front and rear sides of the right end of the frame 1.

The design of the guide plates 21 can play a connecting and supporting role, ensuring the stability of the cooking plate during the process of moving from the cooking rack 8 to the support plate 20.

[0026] In this embodiment, the pallet conveying assembly 4 includes a lifting mechanism and a pallet conveying mechanism. The pallet conveying mechanism includes a pallet conveying frame 22 and several pallet conveying belts 23. The left and right ends of the pallet conveying frame 22 are respectively rotatably provided with a second connecting shaft 25 and a second connecting shaft. Several corresponding pulleys are rotatably provided on the second connecting shaft 25 and the second connecting shaft. The pallet conveying belts 23 are sleeved between the corresponding pulleys on the left and right sides. The bottom center of the pallet conveying frame 22 is provided with a second motor 26 and a drive shaft 27. The second motor 26 is connected to the drive shaft 27 to drive it to rotate. Several drive wheels corresponding to each pallet conveying belt 23 are provided on the drive shaft 27. The pallet conveying belts 23 are connected to the corresponding drive wheels for transmission. The lifting mechanism is used to drive the pallet conveying frame 22 to perform lifting and lowering movements.

[0027] In this embodiment, the lifting mechanism includes several guide rods 29 and several drive belts 30. Several guide rods 29 are provided at both the front and rear ends of the frame 1. The two ends of the pallet frame 22 are slidably mounted on the guide rods 29 on both sides. Several third connecting shafts 31 and fourth connecting shafts 32 are rotatably assembled at the upper and lower ends of the frame 1, respectively. The two ends of the third connecting shafts 31 and the two ends of the fourth connecting shafts 32 are respectively driven by drive belts 30. The two ends of the pallet frame 22 are respectively fixedly connected to the drive belts 30 on the corresponding side. The third connecting shafts 31 are driven by a third motor 28, so that the pallet frame 22 can be moved synchronously by rotating the drive belts 30.

[0028] The distance that the tray conveyor 22 lifts and lowers each time is exactly the distance between two cooking trays. By lifting and lowering the tray conveyor 22 until it contacts the bottom surface of the cooking tray and lifting the cooking tray to detach it from the support plate 20, the cooking tray is then carried by the tray conveyor belt 23. Then, the second motor 26 drives the tray conveyor belt 23 to rotate forward, thereby transporting the cooking tray forward. Finally, the cooking tray is conveyed onto the first conveyor assembly 5 to complete the tray retrieval work. Then, the tray conveyor 22 continues to rise to retrieve other cooking trays.

[0029] In this embodiment, the first conveying assembly 5 includes a first conveying frame 33 and a plurality of first conveyor belts 34. One end of the first conveying frame 33 is rotatably mounted on the pallet frame 22, and the other end of the first conveying frame 33 is rotatably provided with a fifth connecting shaft 35. The first conveyor belts 34 are sleeved between the fifth connecting shaft 35 and the second connecting shaft 25. A fourth motor 36 is provided on the first conveying frame 33, and the output shaft of the fourth motor 36 is connected to the conveyor belts through a pulley drive.

[0030] In this embodiment, the second conveying assembly 6 includes a transition conveying mechanism, a second conveying mechanism, and a support 39. The transition conveying mechanism includes a transition conveyor belt 40, a base 41, and a sixth connecting shaft 42. The base 41 is slidably mounted on the support 39. The fifth connecting shaft 35 is rotatably disposed at the right end of the base 41, and the sixth connecting shaft 42 is rotatably mounted at the left end of the base 41. The transition conveyor belt 40 is sleeved between the fifth connecting shaft 35 and the sixth connecting shaft 42 and rotates synchronously with the rotation of the fifth connecting shaft 35. The second conveying mechanism includes a seventh connecting shaft 43, an eighth connecting shaft 44, and a second conveyor belt 45. A transition opening is provided on the upper side of the base 41. The seventh connecting shaft 43 passes through the transition opening and is rotatably connected to the support 39. The eighth connecting shaft 44 is rotatably mounted on the support 39. The second conveyor belt 45 is sleeved between the seventh connecting shaft 43 and the eighth connecting shaft 44, and the eighth connecting shaft 44 is driven by a fifth motor.

[0031] Since the first conveyor frame 33 is connected to the tray conveyor frame 22 and moves synchronously with the lifting and lowering of the tray conveyor frame 22, when the tray conveyor frame 22 lifts and lowers, it drives the first conveyor frame 33 to rotate around the second connecting shaft 25 as the fulcrum. At this time, the other end of the first conveyor frame 33 will move accordingly. The other end of the first conveyor frame 33 is connected to the base 41 through the fifth connecting shaft 35, which in turn drives the base 41 to move horizontally on the support 39. The transition opening on the base 41 ensures that the base 41 will not contact the second conveying mechanism when moving horizontally, and will not affect the operation of the second conveyor belt 45. Because the vertical movement distance of the first conveying component 5 is large, the path length will change when conveying cooking trays of different heights. However, the position of the second conveying mechanism will not change. Therefore, the horizontal sliding of the transition conveying mechanism adapts to the change in path length. Through this multi-stage continuous conveying, the production efficiency is greatly improved and the labor intensity of workers is reduced.

[0032] The working principle of this embodiment is as follows:

[0033] During the plate retrieval process, the worker first moves the cooking rack 8 containing the cooking plates into the receiving rack 2 until it comes into contact with the limiting member 19. Then, the cylinder 18 operates to drive the baffle 17 to rotate and contact the cooking rack 8, thereby preventing the cooking rack 8 from moving. The first motor 10 drives the connecting rod 16 to rotate, thereby pushing the first drive frame 12 and the second drive frame 13 to extend, so as to drive the pusher frame 11 to move to the left, and then push all the cooking plates on the cooking rack 8 into the carrying rack 3. After the transfer is completed, the baffle 17 opens, and the worker can take out the empty cooking rack 8 and then push in the next cooking rack 8. This can effectively utilize the waiting time during the plate retrieval process and improve work efficiency. Finally, with the coordinated work of the plate transport component 4, the first conveying component 5 and the second conveying component 6, the cooking plates on the carrying rack 3 are removed one by one and transported to the next process.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
