Technical Field
[0001] This utility model relates to the field of filling machine technology, and in particular to a filling machine for baking pastries. Background Technology
[0002] In the pastry production industry, the production process of baked pastries involves several key steps, among which the addition of fillings is an important step that affects the taste and quality of the pastries.
[0003] In the existing technology, the filling of baked pastries is mainly done manually. This method is inefficient, as it requires a lot of manpower and is slow, making it difficult to meet the needs of large-scale production. Furthermore, manual operation makes it difficult to ensure that the amount of filling added to each pastry is completely consistent, which can lead to inconsistent pastry quality and affect product quality stability. To solve the above problems, this application proposes a filling machine for baked pastries. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a baking-type pastry filling machine. The machine uses a motor to drive a transmission rod to rotate, which causes the stirring blade and the spiral conveyor blade to work together. The stirring blade thoroughly stirs the filling to ensure uniform mixing, while the spiral conveyor blade steadily conveys the filling with a fixed number of rotations, resulting in a consistent output amount each time and ensuring uniform filling output, thus guaranteeing consistent pastry quality.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pastry filling machine for baking includes a base, an L-shaped support plate fixedly connected to the top of the base, a filling box fixedly connected to the top of the L-shaped support plate, a feeding hopper fixedly connected to the top of the filling box, a motor fixedly connected to the top of the filling box, a transmission rod fixedly connected to the output end of the motor, the transmission rod passing through the filling box and rotatably connected thereto, multiple stirring blades fixedly connected to the outer wall of the transmission rod, a spiral conveying blade fixedly connected to the outer wall of the transmission rod, a discharge hopper fixedly connected to the bottom of the filling box, the spiral conveying blade located inside the discharge hopper and its outer wall contacting the inner wall of the discharge hopper, a sealing mechanism provided on the discharge hopper, a lifting mechanism provided below the base, and a micro main unit fixedly connected to the front of the base.
[0007] Preferably, the sealing mechanism includes an L-shaped plate disposed on and fixedly connected to the side wall of the discharge hopper. A multi-section electric telescopic rod is fixedly connected to one end of the L-shaped plate near the discharge hopper. A baffle is fixedly connected to the output end of the multi-section electric telescopic rod. Two distance sensors are installed at the bottom of the baffle.
[0008] Preferably, the lifting mechanism includes a groove formed at the bottom of the base, a hydraulic rod is fixedly connected to the top of the groove, a lifting plate is fixedly connected to the output end of the hydraulic rod, two L-shaped guide rods are fixedly connected to the inner wall of the groove, both L-shaped guide rods pass through the lifting plate and are slidably connected to it, and four locking casters are installed at the bottom of the lifting plate.
[0009] Preferably, the top of the baffle is disposed on the same horizontal plane as the bottom of the discharge hopper.
[0010] Preferably, the bottom of the baffle has two mounting slots, and the two ranging sensors are respectively mounted on the inner wall of the mounting slots and fixedly connected thereto.
[0011] Preferably, the four locking casters are positioned at equal intervals.
[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] 1. The two distance sensors at the bottom of the baffle can accurately detect the position and thickness of the dough. Combined with the micro-host to control the movement of the multi-section electric telescopic rod, the opening and closing timing of the hopper can be accurately grasped, so as to achieve precise control of the filling position and timing, ensuring that the filling falls accurately on the dough and avoiding filling deviation or misplacement.
[0014] 2. The motor drives the transmission rod to rotate, so that the stirring blade and the spiral conveyor blade work together. The stirring blade fully stirs the filling to ensure that it is mixed evenly, while the spiral conveyor blade steadily conveys the filling with a fixed number of rotations. The amount of filling discharged each time is consistent, so as to achieve uniform discharge of filling and ensure the uniform quality of pastries.
[0015] 3. All components work together under the control of the micro-host. From dough detection, stopping the conveyor, opening the outlet to adding filling, a series of actions are completed automatically, reducing manual intervention, lowering labor costs, and improving production efficiency.
[0016] 4. The sealing mechanism, consisting of an L-shaped plate, multiple sections of electric telescopic rods, and baffles, can effectively seal the discharge hopper, preventing filling leakage when not adding filling, keeping the working environment clean, and can be quickly opened when adding filling to ensure filling efficiency.
[0017] In summary, by driving the transmission rod with a motor, the stirring blades and the spiral conveyor blades work together. The stirring blades thoroughly agitate the filling to ensure uniform mixing, while the spiral conveyor blades steadily convey the filling with a fixed number of rotations, resulting in consistent output of the filling each time and ensuring uniform quality of the pastries.

Detailed Implementation
[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-2 A pastry filling machine for baking includes a base 1, which supports the entire machine and provides a stable mounting base for other components. An L-shaped support plate 2 is fixedly connected to the top of the base 1, and a filling box 3 is fixedly connected to the top of the L-shaped support plate 2. The L-shaped support plate 2 supports the filling box 3, which stores fillings and provides raw materials for filling operations. A feed hopper 4 is fixedly connected to the top of the filling box 3, and a motor 5 is fixedly connected to the top of the filling box 3. The motor 5 serves as a power source, providing driving force for mixing and conveying the fillings.
[0023] A transmission rod 6 is fixedly connected to the output end of the motor 5. The transmission rod 6 passes through the filling box 3 and is rotatably connected to it. Multiple stirring blades 7 are fixedly connected to the outer wall of the transmission rod 6. The stirring blades 7 stir the filling by rotating, so as to mix it evenly and ensure the quality of the filling. A spiral conveying blade 8 is fixedly connected to the outer wall of the transmission rod 6. The spiral conveying blade 8 is used to evenly convey the filling in the filling box 3 to the discharge hopper 9. The bottom of the filling box 3 is fixedly connected to the discharge hopper 9. The spiral conveying blade 8 is located in the discharge hopper 9 and the outer wall of the spiral conveying blade 8 is in contact with the inner wall of the discharge hopper 9. The discharge hopper 9 is the channel for discharging the filling and conveying the filling to the dough.
[0024] The discharge hopper 9 is equipped with a sealing mechanism, which includes an L-shaped plate 10 fixedly connected to the side wall of the discharge hopper 9. A multi-section electric telescopic rod 11 is fixedly connected to one end of the L-shaped plate 10 near the discharge hopper 9. A baffle 12 is fixedly connected to the output end of the multi-section electric telescopic rod 11. The top of the baffle 12 is set on the same horizontal plane as the bottom of the discharge hopper 9. The multi-section electric telescopic rod 11 drives the baffle 12 to move through the telescopic action, thereby controlling the opening and closing of the discharge hopper 9. Two distance sensors 13 are installed at the bottom of the baffle 12. The distance sensors 13 are used to detect the position of the dough and provide a trigger signal for the filling operation. Two mounting slots are opened at the bottom of the baffle 12. The two distance sensors 13 are respectively set on the inner wall of the mounting slots and fixedly connected to them.
[0025] A lifting mechanism is provided below the base 1. The lifting mechanism includes a groove at the bottom of the base 1. A hydraulic rod 14 is fixedly connected to the top of the groove. The hydraulic rod 14 drives the lifting plate 15 to rise and fall through its extension and retraction action, adjusting the height of the entire machine to match the height of the external conveyor belt. The output end of the hydraulic rod 14 is fixedly connected to the lifting plate 15. Two L-shaped guide rods 16 are fixedly connected to the inner wall of the groove. Both L-shaped guide rods 16 pass through the lifting plate 15 and are slidably connected to it. The L-shaped guide rods 16 guide and limit the rise and fall of the lifting plate 15 to ensure smooth lifting. Four locking casters 17 are installed at the bottom of the lifting plate 15. The four locking casters 17 are evenly distributed and facilitate the movement and positioning of the entire machine. A micro-host 18 is fixedly connected to the front of the base 1. The micro-host 18 is used to receive signals from the ranging sensor 13 and control the various components to work together to achieve automated filling.
[0026] In this invention, the worker injects the filling into the filling box 3 through the feeding hopper 4. An external conveyor motor drives a conveyor belt and the dough placed on the conveyor belt for transport. When the dough is transported below the baffle 12, the distance sensor 13 on the left first detects a change in distance (the distance sensor 13 originally detects the distance to the conveyor belt; when the dough is transported below, it detects the distance to the dough itself; the difference between the two distances is the thickness of the dough). As the conveyor belt continues to move the dough, the distance sensor 13 on the right also detects a change in distance. Both distance sensors 13 transmit the detected distance change information to the micro-host 18. Upon receiving the information, the micro-host 18 controls the external conveyor motor to stop, bringing the dough to a standstill to facilitate the subsequent addition of filling. The micro-host 18 also controls the multi-section electric telescopic rod 11 to start, causing the baffle 12 to move to the right. When the distance detected by the two ranging sensors 13 returns to the spacing of the conveyor belt, it indicates that the baffle 12 opens the discharge hopper 9. The output end of the motor 5 is controlled by the micro-host 18 to rotate a fixed number of times. The output end of the motor 5 drives the transmission rod 6, multiple stirring blades 7 and spiral conveying blades 8 to rotate. The rotation of the stirring blades 7 can stir the filling to make it evenly mixed. The rotation of the spiral conveying blades 8 conveys the filling through the discharge hopper 9 and discharges it. The spiral conveying blades 8 rotate an equal number of times each time to achieve uniform discharge of the filling, so that the filling falls onto the dough, completing the filling operation. After the filling is completed, the staff will shape the dough with the filling and then place it in the oven for baking, finally completing the pastry making.
