Description

Technical Field

[0001] This utility model relates to the technical field of bread processing, specifically to a bread dough pretreatment spreading device. Background Technology

[0002] Bread is a food made by grinding grains into flour and heating it. Wheat flour is the main ingredient, with yeast, eggs, oil, sugar, salt, and other ingredients added as auxiliary materials. Water is added to form a dough, which is then processed through dividing, shaping, proofing, baking, and cooling. Bread is formed through the fermentation and baking of the dough. Before baking, the ingredients need to be sprinkled onto the dough.

[0003] According to Chinese Patent No. CN215775169U, a dough surface material spreading device includes a placement platform, a fixing frame located on top of the placement platform, and a material box located on top of the fixing frame. The placement platform includes a trough disposed on both sides inside the placement platform, a fixing groove disposed on both sides at the bottom of the placement platform, and a collection groove disposed inside both sets of fixing grooves. A limiting groove is disposed on top of the placement platform, and a scraper is disposed inside the limiting groove. A motor is disposed on one side of the limiting groove.

[0004] In the above scheme, the material is spread by a motor, a threaded rod, a first motor, a connecting rod, and a fixing plate. This results in the following disadvantages: the spreading device cannot achieve quantitative spreading of the material during use, leading to situations where too much or too little material is spread, thereby increasing material waste and reducing bread quality. Utility Model Content

[0005] The purpose of this invention is to provide a material spreading device for bread dough pretreatment, in order to solve the problem that the spreading device cannot achieve quantitative spreading of materials during use, resulting in too much or too little spreading, thereby increasing material waste and reducing bread quality.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a bread dough pretreatment sprinkling device, comprising a U-shaped frame, the U-shaped frame being fixed to the top surface of a U-shaped base, a PLC controller being fixed to the right side of the outer wall of the U-shaped base, a sprinkling box being movably arranged inside the U-shaped frame, a discharge hole being opened on the bottom surface of the sprinkling box, a rotating column being rotatably arranged inside the sprinkling box, a storage groove being opened on the top surface of the rotating column, a rotating hole being opened on the right side of the outer wall of the sprinkling box, a drive motor being fixed to the right side of the outer wall of the sprinkling box, the output shaft of the drive motor being rotatably arranged in the rotating hole and fixedly connected to the rotating column, and a conveyor belt being provided inside the U-shaped base, the conveyor belt being electrically connected to the PLC controller.

[0007] Preferably, a U-shaped plate is fixed to the top surface of the U-shaped base, and an infrared sensor is detachably installed on the inner top surface of the U-shaped plate. The infrared sensor is electrically connected to the PLC controller.

[0008] Preferably, the top surface of the U-shaped frame has a movable hole, and an electric push rod is fixed on the top surface of the U-shaped frame. The electric push rod is electrically connected to the PLC controller, and one end of the telescopic rod of the electric push rod passes through the movable hole and is fixedly connected to the material dispensing box.

[0009] Preferably, the top surface of the U-shaped frame has two limiting holes, and limiting posts are slidably inserted into the two limiting holes respectively. The bottom ends of the two limiting posts are fixedly connected to the top surface of the material spreading box.

[0010] Preferably, the outer wall of the material dispensing box has a feeding hole on the front side, and a feeding pipe is fixed inside the feeding hole.

[0011] Preferably, the front and rear sides of the U-shaped plate are respectively provided with threaded grooves, the front and rear sides of the infrared sensor are respectively fixed with fixing plates, one side of each of the two fixing plates is provided with threaded holes, and bolts are threaded into each of the two threaded holes, and the threaded ends of the two bolts are respectively threaded into the two threaded grooves.

[0012] Compared with the prior art, the bread dough pretreatment sprinkling device that adopts the above technical solution has the following beneficial effects:

[0013] 1. In operation, initially, the storage slot on the rotating column is at the top. Workers place dough on the conveyor belt for transport. When the dough reaches below the dispensing box, the conveyor belt stops, and the worker starts the drive motor, causing the rotating column to rotate and the storage slot to rotate downwards. At this point, the material inside the storage slot falls downwards and is sprinkled onto the dough through the discharge hole. After dispensing, the drive motor starts again, causing the rotating column to rotate and the storage slot to rotate upwards again, filling it with material for the next dispensing. Through the coordinated use of the rotating column, storage slot, and drive motor, and by ensuring that the storage slot can hold a fixed amount of material at a time, the output shaft of the drive motor rotates the storage slot so that the opening faces downwards for dispensing. This facilitates precise dispensing of material, preventing excessive or insufficient dispensing, reducing material waste, and improving bread quality.

[0014] Second, during operation, when the dough is conveyed by the conveyor belt, it passes under the infrared sensor. The sensor detects the dough and transmits this information to the PLC controller, which then stops the conveyor belt after a five-second delay. This ensures the dough accurately stops below the dispensing box, achieving precise dough positioning and improving dispensing accuracy. By activating the electric push rod, the dispensing box can be raised and lowered, thus adjusting the distance between the box and the dough on the conveyor belt. This height adjustment allows for customization based on the needs of different dough types, enhancing the device's flexibility and adaptability.

[0015] Thirdly, during use, the combination of the limiting hole and the limiting post facilitates the limiting of the material dispensing box, ensuring that it will not deviate or shake during lifting and lowering, thus improving the stability of the dispensing box during lifting and lowering. The combination of the feeding hole and the feeding pipe facilitates the delivery of materials into the dispensing box by the operator. When the material in the dispensing box decreases, it can be replenished in a timely manner through the feeding pipe, ensuring continuous dispensing. The combination of the fixing plate and bolts facilitates the disassembly and assembly of the infrared sensor by the operator, thereby facilitating the maintenance or replacement of the infrared sensor.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4As shown, a bread dough pretreatment spreading device includes a U-shaped frame 1, which is fixed to the top surface of a U-shaped base 2. A PLC controller is fixed to the right side of the outer wall of the U-shaped base 2. The PLC controller is a Siemens S7-300. A spreading box 3 is movably arranged inside the U-shaped frame 1. A discharge hole 4 is opened on the bottom surface of the spreading box 3. A rotating column 5 is rotatably arranged inside the spreading box 3. A storage groove 6 is opened on the top surface of the rotating column 5. A rotating hole 7 is opened on the right side of the outer wall of the spreading box 3. A drive motor 8 is fixed to the right side of the outer wall of the spreading box 3. The output shaft of the drive motor 8 is rotatably arranged in the rotating hole 7 and fixedly connected to the rotating column 5. A conveyor belt 9 is provided inside the U-shaped base 2. The conveyor belt 9 is electrically connected to the PLC controller.

[0023] In operation, initially, the storage slot 6 on the rotating column 5 is positioned at the top. The operator places the dough on the conveyor belt 9 for transport. When the dough is transported to the bottom of the material distribution box 3, the conveyor belt 9 is stopped. Then, the operator starts the drive motor 8, causing the rotating column 5 to rotate 180 degrees, which in turn causes the storage slot 6 to rotate downwards. At this time, the material inside the storage slot 6 falls downwards and is sprinkled onto the dough through the discharge hole 4. The bottom of the material distribution box 3 has a semi-cylindrical cavity structure that matches the rotating column 5, preventing the material from falling between the inner wall of the material distribution box 3 and the side wall of the rotating column 5. After the material is sprinkled, the drive motor 8 is started again, causing the rotating column 5 to rotate 180 degrees, which causes the storage slot 6 to rotate upwards again, filling it with material to prepare for the next sprinkling. By using the rotating column 5, storage tank 6, and drive motor 8 in combination, and by storing only a fixed amount of material in the storage tank 6 at a time, the output shaft of the drive motor 8 rotates, causing the storage tank 6 to rotate so that the opening faces downwards to allow the material to be dispensed. This facilitates the quantitative dispensing of material, prevents excessive or insufficient dispensing, reduces material waste, and improves the quality of bread.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a U-shaped plate 10 is fixed on the top surface of the U-shaped base 2. An infrared sensor 11 is detachably installed on the top surface inside the U-shaped plate 10. The infrared sensor 11 is electrically connected to the PLC controller.

[0025] During use, when the dough is conveyed by the conveyor belt 9, the dough passes under the infrared sensor 11. At this time, the infrared sensor 11 detects the dough and transmits the information to the PLC controller, which delays for five seconds and stops the conveyor belt 9 to ensure that the dough accurately stops under the feeding box 3. This achieves precise positioning of the dough and improves the accuracy of feeding.

[0026] like Figures 1-3As shown, the top surface of the U-shaped frame 1 has a movable hole 12, and an electric push rod 13 is fixed on the top surface of the U-shaped frame 1. The electric push rod 13 is electrically connected to the PLC controller. One end of the telescopic rod of the electric push rod 13 passes through the movable hole 12 and is fixedly connected to the material spreading box 3. The top surface of the U-shaped frame 1 has two limiting holes 14. Limiting posts 15 are slidably inserted into the two limiting holes 14 respectively. The bottom ends of the two limiting posts 15 are fixedly connected to the top surface of the material spreading box 3 respectively.

[0027] During use, the electric push rod 13 allows the material dispenser box 3 to be raised and lowered, thereby adjusting the distance between the material dispenser box 3 and the dough on the conveyor belt 9. This height adjustment is tailored to the needs of different dough types, improving the flexibility and adaptability of the device. The use of the limiting hole 14 and the limiting post 15 effectively limits the material dispenser box 3, ensuring it does not shift or shake during raising and lowering, thus improving its stability.

[0028] like Figures 1-4 As shown, a feed hole 16 is provided on the front side of the outer wall of the feed box 3. A feed pipe 17 is fixed inside the feed hole 16. Threaded grooves 18 are provided on the front and rear sides of the U-shaped plate 10. Fixing plates 19 are fixed on the front and rear sides of the infrared sensor 11. Threaded holes 20 are provided on one side of the two fixing plates 19. Bolts 21 are threaded into the two threaded holes 20. The threaded ends of the two bolts 21 are threaded into the two threaded grooves 18.

[0029] During use, the feeding port 16 and the feeding pipe 17 work together to facilitate the delivery of materials into the spreading box 3. When the material in the spreading box 3 decreases, it can be replenished in time through the feeding pipe 17 to ensure the continuity of spreading. The fixing plate 19 and the bolts 21 work together to facilitate the disassembly and assembly of the infrared sensor 11, thereby making it easy to maintain or replace the infrared sensor 11.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
