Description

Technical Field

[0001] This utility model relates to the field of dough product processing technology, specifically to an automatic dough dividing device. Background Technology

[0002] Dough is a mixture of flour and other ingredients, with varying consistency, that can be kneaded or rolled. It's a common food in home kitchens, used to make all sorts of delicious foods, such as various shapes of pastries. In the process of making pastries, the kneaded dough needs to be divided into smaller pieces of appropriate size for later processing such as steaming. Traditional dough division is mostly done manually, which is labor-intensive, inefficient, and makes it difficult to ensure consistent weight, resulting in inconsistent product quality. With the large-scale development of the food industry, the demand for efficient and precise automatic dough dividing devices is increasingly urgent, leading to the emergence of many automatic dough cutting devices.

[0003] Existing automatic dough cutting devices typically use auger blades to extrude dough from the outlet, and then hydraulic cylinders drive the cutting blades up and down to cut the dough. By adjusting the time interval between the two cutting sides, the dough can be cut into dough pieces of different sizes. However, because the surface of the freshly extruded dough pieces is somewhat sticky, the dough pieces tend to stick to the surface of the cutting blades during the cutting process, requiring cleaning of the blade surface. This seriously affects the production efficiency and product quality.

[0004] Therefore, it is necessary to invent an automatic dough dividing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic dough dividing device to solve the problems in the technology where dough portions easily stick to the surface of the cutting blades, and when dough portions fall into the receiving tray, multiple dough portions pile up together, which can also cause the dough portions to stick together and affect subsequent processing and production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic dough dividing device, comprising a conveyor belt, an extrusion box mounted on the upper side of the conveyor belt, a fixed support fixedly connected to the front end of the extrusion box, a cylinder fixedly mounted at the front end of the fixed support, a cutting blade fixedly connected to the lower end of the telescopic rod in the cylinder, and a powder spraying structure provided at the front end of the extrusion box, the powder spraying structure comprising a storage box, an electric motor, a feeding hopper, a feeding pipe, a second spiral blade, a small blower, an exhaust pipe, a connecting pipe, a diverting pipe, and a spray head.

[0007] By adopting the above technical solution, the extrusion box is used to extrude the dough, and the storage box is used to store dry flour. During the extrusion process, a small blower sprays the dry flour inside the storage box outward through two sets of spray nozzles, spraying the dry flour onto the surface of the extruded dough. At this time, the dry flour will reduce the stickiness of the dough surface, preventing the dough from sticking to the surface of the cutting blades during the cutting process. At the same time, the conveyor belt is used to transport the cut dough, preventing the dough from piling up together, thus preventing the dough from sticking together and facilitating subsequent processing of the dough.

[0008] Optionally, the storage box is fixedly installed on the upper side of the fixed bracket, the feeding hopper is fixedly connected to the lower end of the storage box, the feeding pipe is fixedly connected to the lower end of the feeding hopper, and the second spiral blade is rotatably connected to the feeding pipe.

[0009] By adopting the above technical solution, the hopper is funnel-shaped, which facilitates the downward collection of dry flour.

[0010] Optionally, the electric motor is fixedly installed at the middle position of the upper end of the storage box, and a transmission rod is fixedly connected to the output end of the electric motor. The lower end of the transmission rod is fixedly connected to the upper end of the second spiral blade.

[0011] By adopting the above technical solution, the output end of the electric motor drives the second spiral blade to rotate through the transmission rod, thereby discharging the dry flour inside the hopper through the discharge pipe.

[0012] Optionally, the upper surface of the storage box is provided with two sets of feed inlets.

[0013] By adopting the above technical solution, dry flour is fed into the storage box through the feed inlet.

[0014] Optionally, the small blower is fixedly installed on the front surface of the extrusion box, the exhaust pipe is fixedly connected to the air outlet of the small blower, a connecting pipe is fixedly connected to the surface of the exhaust pipe, and the connecting pipe is fixedly connected to the lower end of the discharge pipe.

[0015] By adopting the above technical solution, the feeding pipe discharges dry flour into the interior of the exhaust pipe, at which point a small blower, in conjunction with the exhaust pipe, sprays the dry flour outward.

[0016] Optionally, the diversion pipe is U-shaped, the front end of the exhaust pipe is fixedly connected to the middle of the diversion pipe, and both ends of the diversion pipe are fixedly connected to a spray head, which is located on the left and right sides of the cutting blade, respectively.

[0017] By adopting the above technical solution, the exhaust pipe, together with the diversion pipe, sprays dry flour onto the surface of the extruded dough.

[0018] Optionally, the extrusion box has an extrusion groove inside, the front end of the extrusion groove is fixedly connected to a discharge pipe, and the front end of the discharge pipe is fixedly connected to a discharge head.

[0019] By adopting the above technical solution, the discharge head can be replaced, and the size of the discharge head can be adjusted according to the required size of the dough.

[0020] Optionally, the extrusion trough and the discharge pipe are internally rotatably connected with a first spiral blade, and a servo motor is fixedly installed at the rear end of the extrusion box. The output end of the servo motor is fixedly connected to the rear end of the first spiral blade through a coupling.

[0021] By adopting the above technical solution, the kneaded dough is placed inside the extrusion trough. At this time, the servo motor drives the first spiral blade to rotate, squeezing the dough forward and then extruding the dough through the discharge head.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] 1. This utility model uses a small blower to spray the dry flour inside the storage box outward through two sets of spray nozzles, spraying the dry flour onto the surface of the extruded dough. At this time, the dry flour will reduce the stickiness of the dough surface, preventing the dough from sticking to the surface of the cutting blade during the cutting process, making it easier to cut the dough later, effectively improving the ease of use of the equipment, and improving production efficiency and production quality.

[0024] 2. This utility model utilizes a conveyor belt to transport the slit dough pieces, preventing them from piling up and sticking together, thus facilitating subsequent processing and further improving the ease of equipment production. Attached Figure Description

[0034] This utility model provides, for example Figures 1 to 3 An automatic dough dividing device is shown, including a conveyor belt 1, an extrusion box 2 installed on the upper side of the conveyor belt 1, a fixed bracket 3 fixedly connected to the front end of the extrusion box 2, a cylinder 31 fixedly installed at the front end of the fixed bracket 3, a cutting blade 32 fixedly connected to the lower end of the telescopic rod in the cylinder 31, an extrusion groove 21 opened inside the extrusion box 2, a discharge pipe 22 fixedly connected to the front end of the extrusion groove 21, a discharge head 25 fixedly connected to the front end of the discharge pipe 22, a first spiral blade 23 rotatably connected inside the extrusion groove 21 and the discharge pipe 22, and a servo motor 24 fixedly installed at the rear end of the extrusion box 2, the output end of the servo motor 24 being fixedly connected to the rear end of the first spiral blade 23 through a coupling.

[0035] During use, the corresponding discharge head 25 is first replaced according to the specifications of the product. The kneaded dough is then placed inside the extrusion box 2. The servo motor 24 is then started, and the output of the servo motor 24 drives the first spiral blade 23 to rotate. The first spiral blade 23 extrudes and conveys the dough forward, and then the dough is extruded through the discharge head 25 on the front side. At this time, the telescopic rod in the cylinder 31 pushes the cutting blade 32 downward to cut the extruded dough into dough pieces. The cut dough pieces fall onto the surface of the conveyor belt 1, and the conveyor belt 1 conveys them forward to avoid multiple dough pieces from piling up together.

[0036] See Figure 1 , Figures 4 to 6The front end of the extrusion box 2 is equipped with a powder spraying structure, which includes a storage box 4, an electric motor 42, a feeding hopper 44, a feeding pipe 45, a second spiral blade 46, a small blower 5, an exhaust pipe 51, a connecting pipe 52, a diverting pipe 53, and a spray head 54. The storage box 4 is fixedly installed on the upper side of the fixed bracket 3. A cylinder 31 is fixedly installed at the front end of the fixed bracket 3. A cutting blade 32 is fixedly connected to the lower end of the telescopic rod in the cylinder 31. The feeding hopper 44 is fixedly connected to the lower end of the storage box 4, and the feeding pipe 45 is fixedly connected to the lower end of the feeding hopper 44. The second spiral blade 46 is rotatably connected to the feeding pipe 45. The electric motor 42 is fixedly installed on the upper part of the storage box 4. At the position of the electric motor 42, the output end of the electric motor 42 is fixedly connected to the transmission rod 43, the lower end of the transmission rod 43 is fixedly connected to the upper end of the second spiral blade 46, the upper surface of the storage box 4 is provided with two sets of feed inlets 41, the small blower 5 is fixedly installed on the front surface of the extrusion box 2, the exhaust pipe 51 is fixedly connected to the air outlet of the small blower 5, the surface of the exhaust pipe 51 is fixedly connected to the connecting pipe 52, the connecting pipe 52 is fixedly connected to the lower end of the discharge pipe 45, the diversion pipe 53 is U-shaped, the front end of the exhaust pipe 51 is fixedly connected to the middle part of the diversion pipe 53, and both ends of the diversion pipe 53 are fixedly connected to the spray nozzles 54, which are located on the left and right sides of the cutting blade 32 respectively.

[0037] In addition, before the dough is extruded, dry flour is first filled into the storage box 4. When the servo motor 24 is started, the electric motor 42 and the small blower 5 are started simultaneously. The small blower 5 draws outside air into the exhaust pipe 51. Then the airflow is discharged through both ends of the split pipe 53. At the same time, the electric motor 42 drives the transmission rod 43 to rotate. The transmission rod 43 drives the second spiral blade 46 to rotate, discharging the dry flour in the storage box 4 into the exhaust pipe 51 through the feed pipe 45. At this time, the dry flour will be sprayed out from the spray nozzles 54 at both ends of the split pipe 53 along with the airflow inside the exhaust pipe 51, spraying the dry flour onto the surface of the extruded dough. At this time, the dry flour effectively reduces the stickiness of the dough surface, and the surface of the slitting blade 32 will also be covered with dry flour. Thus, during the slitting process, the dough will not stick to the surface of the slitting blade 32, eliminating the need to clean the surface of the slitting blade 32. This allows the dough to be slitted quickly, effectively improving the equipment's efficiency and production quality.

[0038] The working principle of this utility model is as follows: A small blower 5 sprays the dry flour inside the storage bin 4 outward through two sets of spray nozzles 54, sprinkling the dry flour onto the surface of the extruded dough. At this time, the dry flour reduces the stickiness of the dough surface, preventing the dough from sticking to the surface of the slitting blade 32 during the slitting process, making it easier to slit the dough for subsequent processing, effectively improving the ease of use of the equipment, and increasing production efficiency and quality. At the same time, the conveyor belt 1 transports the slit dough, preventing it from piling up and sticking together, thus facilitating subsequent processing of the dough and further improving the ease of production of the equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
