Detailed Implementation
[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] like Figure 1-3 As shown, this utility model provides an automatic salt and sugar spreading machine, including a frame. The frame is equipped with a linear conveyor mechanism for transporting materials. The linear conveyor mechanism includes a conveyor belt 7, multiple transmission rollers for driving the conveyor belt 7 to rotate, and a drive motor 8 for driving the transmission rollers to rotate. The frame is equipped with a sugar spreading mechanism and a salt spreading mechanism distributed at intervals. The sugar spreading mechanism includes a first hopper 6, a first discharge plate 9 disposed inside the first hopper 6, and a first lifting cylinder 4 disposed on the top of the first hopper 6 for driving the first discharge plate 9 to move up and down. The top of the first hopper 6 is equipped with a first protective cover 5 detachably connected to it. The first protective cover 5 has a first movable groove. The first lifting cylinder 4 is fixedly installed on the first protective cover 6. The first material bin 6 is located at the top, and the output shaft of the first lifting cylinder 4 passes through the first movable groove and is driven to connect with the first discharge plate 9. The first material bin 6 includes a first straight cylindrical part 10, a second straight cylindrical part 12, and a first conical part 13 from top to bottom. The outer diameter of the second straight cylindrical part 12 is larger than the outer diameter of the first straight cylindrical part 10. The bottom end of the first discharge plate 9 has a first baffle part 11 with an inclined angle. The outer side of the first baffle part 11 is in contact with but not connected to the inner wall of the first straight cylindrical part 10. When the first lifting cylinder 4 is not activated, it acts to block the sugar. When the first lifting cylinder 4 drives the first discharge plate 9 to descend, the sugar falls along the first baffle part 11 into the second straight cylindrical part 12 and then falls along the first conical part 13.
[0021] The salt-spreading mechanism includes a second hopper 3, a second discharge plate 14 disposed inside the second hopper 3, and a second lifting cylinder 1 disposed on the top of the second hopper 3 for driving the second discharge plate 14 to move up and down. The top of the second hopper 3 is provided with a second protective cover 2 detachably connected to it. The second protective cover 2 has a second movable groove. The second lifting cylinder 1 is fixedly installed at the bottom of the second hopper 3, and the output shaft of the second lifting cylinder 1 passes through the second movable groove and is drivenly connected to the second discharge plate 14. The second hopper 3 includes a third straight cylinder from top to bottom. The third straight cylinder 16 has a larger outer diameter than the fourth straight cylinder 18. The bottom end of the second discharge plate 14 has a second baffle 17 with an inclined angle. The outer side of the second baffle 17 is in contact with but not connected to the inner wall of the third straight cylinder 16. When the second lifting cylinder 1 is not activated, it acts to block the sugar. When the second lifting cylinder 1 drives the second discharge plate 14 to descend, the sugar falls into the fourth straight cylinder 18 along the second baffle 17 and then falls along the second conical part 19.
[0022] Compared to traditional technology: The sugar-spreading mechanism includes a first hopper 6, a first discharge plate 9, and a first lifting cylinder 4. Since the first hopper 6 comprises a first straight cylindrical section 10, a second straight cylindrical section 12, and a first conical section 13 from top to bottom, when the first lifting cylinder 4 drives the first discharge plate 9 to descend a certain distance, the sugar placed inside the first hopper 6 is spread along the first discharge plate 9 and the first conical section 13 onto the food located on the conveyor belt 7. The sugar dispensing distance can be controlled by controlling the descent distance of the first discharge plate 9. The salt-spreading mechanism includes a second hopper 3, a second discharge plate 14, and a second lifting cylinder 1. Since the second hopper 3 includes a third straight cylinder 16, a fourth straight cylinder 18, and a second conical section 19 from top to bottom, when the second lifting cylinder 1 drives the second discharge plate 14 to descend a certain distance, the salt placed inside the second hopper 3 is spread along the second discharge plate 14 and the second conical section 19 onto the food located on the conveyor belt 7. The amount of salt dispensed can be controlled by controlling the descent distance of the second discharge plate 14.
