Description

Technical Field

[0001] This utility model relates to the field of bread processing, and in particular to an automatic bread filling device. Background Technology

[0002] In the bread production industry, filling is a crucial step affecting product quality and production efficiency. Traditional bread filling is mostly done manually or with semi-automated equipment. Manual filling relies on the operator's experience, which not only makes it difficult to control the filling amount, resulting in uneven distribution of filling in the same batch of products and affecting the consistency of taste, but also leads to high labor costs and low production efficiency, making it unable to meet the needs of large-scale industrial production.

[0003] While semi-automatic filling equipment improves efficiency to some extent, it still has many drawbacks. Some equipment uses a fixed filling structure, requiring the bread to be paused during filling, which can easily cause production interruptions and reduce the overall production line cycle time. As the food industry develops towards automation and high precision, the market urgently needs an automatic bread filling device that can achieve continuous, accurate, and stable filling, and is simple in structure and reliable in operation. Summary of the Invention

[0004] To address the shortcomings mentioned above in the background technology, this utility model provides an automatic bread filling device.

[0005] The present invention adopts the following technical solution: An automatic bread filling device, characterized in that the device comprises: A frame, the frame being provided with a conveyor belt for conveying bread, and a back panel being provided on one side of the frame; A filling mechanism, comprising a filling cylinder, a piston, and a placement frame, wherein the filling cylinder is disposed above the conveyor belt and is capable of moving left and right in the horizontal direction, and its moving direction and speed are consistent with those of the conveyor belt; the piston of the filling cylinder is mounted on the bottom surface of the placement frame, and the placement frame is provided with a filling bucket for feeding the filling cylinder. The drive mechanism includes a drive disk, a mounting shaft, an adapter arm, a connecting shaft, a ring sleeve, and a connecting arm. The mounting shaft is eccentrically arranged on the surfaces of the two drive disks. The mounting shaft rotatably passes through the back plate and is fixedly connected to the head end of the adapter arm. The head end of the adapter arm is hinged to the placement frame through the connecting shaft. The outer ring surfaces of the two drive disks are rotatably fitted with ring sleeves, and the two ring sleeves are connected by the connecting arm. The drive mechanism is used to drive the placement rack and the piston to perform horizontal and vertical movements above the conveyor belt, so that the piston can push the filling cylinder to move horizontally and move up and down inside the filling cylinder; during the movement, the piston sucks and squeezes out the filling inside the filling cylinder.

[0006] As a further improvement, the outer side of the filling cylinder is slidably engaged with the polished rod via a sliding part, and the polished rod is fixed to the back plate via a mounting part.

[0007] As a further improvement, the filling container is equipped with a stirrer, which is driven by a driven gear and a driving gear, and the driving gear is coaxially connected to the mounting shaft.

[0008] As a further improvement, one of the drive disks is driven by a motor mounted on the back plate, and the motor output shaft is coaxially arranged with the mounting shaft corresponding to the drive disk.

[0009] As described above, this utility model has the following advantages compared to existing technologies: It mainly consists of a frame, a filling mechanism, and a drive mechanism, enabling automated and precise filling of bread fillings. The frame provides stable support, and the conveyor belt speed is adjustable and synchronized with the filling mechanism, ensuring precise bread positioning. The filling mechanism includes a filling cylinder, a piston, a placement rack, and a filling container. The filling cylinder moves smoothly, and the filling container acts as a transitional feeding mechanism. The drive mechanism is the core power source, driving the drive discs via a servo motor. The motor output shaft is coaxial with the mounting shaft, reducing power loss and deviation. The two drive discs are synchronized via a ring and connecting arm, driving the mounting shaft and adapter arm to achieve horizontal and vertical movement of the placement rack, thereby allowing the piston to complete the filling suction and extrusion. Through the coordinated work of these mechanisms, automated and precise filling of bread fillings can be achieved, effectively improving the efficiency and quality of bread production and reducing labor costs.

[0012] Figure 3 This is an exploded structural diagram of the filling mechanism and the drive mechanism. Detailed Implementation

[0013] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0014] As attached Figure 1 As shown, an automatic bread filling device is provided. The device mainly consists of three parts: a frame 1, a filling mechanism 2, and a drive mechanism 3. Each part works together to complete the automatic bread filling process.

[0015] As attached Figure 1As shown, the frame 1 serves as the supporting foundation for the entire device, and its structural design directly affects the stability and reliability of the device's operation. The frame 1 is welded from high-strength steel and undergoes precise processing and debugging to ensure that the overall structure has sufficient rigidity and stability to withstand the weight of the filling mechanism 2, the drive mechanism 3, and the bread 12 during the conveying process. At the same time, it effectively resists the vibration and impact generated during the operation of the device, preventing the filling accuracy from being affected by frame deformation.

[0016] A conveyor belt 11 for conveying bread 12 is installed on the main frame of the frame 1. The conveyor belt 11 is made of food-grade polyurethane, which has good wear resistance, oil resistance, and corrosion resistance, and meets food hygiene standards, ensuring the safety and hygiene of the bread 12 during the conveying process. The width and length of the conveyor belt 11 can be customized according to actual production needs to accommodate the conveying requirements of bread 12 of different sizes. The conveyor belt 11 is driven by a motor, and its running speed can be precisely adjusted by a frequency converter, which can maintain a high degree of synchronization with the working rhythm of the subsequent filling mechanism 2, ensuring that each bread 12 accurately reaches the filling position and avoiding missed filling or duplicate filling.

[0017] In addition, a back plate 13 is fixedly installed on one side of the frame 1. The back plate 13 is also made of high-quality steel, and its surface has been finely polished and rust-proofed, providing a stable support platform for the installation of the filling mechanism 2 and the drive mechanism 3. The back plate 13 has multiple precise mounting holes, which facilitates the installation, debugging and maintenance of each component, while ensuring that each mechanism can maintain an accurate relative position during operation, thus ensuring the normal operation of the device.

[0018] As attached Figure 2 and Figure 3 As shown, the filling mechanism 2 is the key actuator for filling the bread 12. It mainly includes a filling cylinder 21, a piston 22 and a placement rack 23. It is also equipped with auxiliary components such as a filling bucket 4, a smooth rod 24, a mounting part 25 and a sliding part 26. All components work together to complete the storage, transportation and filling of the filling.

[0019] The filling cylinder 21 is the core component for filling. Its internal cavity stores the filling to be filled, and the piston 22 moves to draw and expel the filling. The filling cylinder 21 is made of stainless steel, offering excellent corrosion resistance and hygiene, facilitating cleaning and sterilization, and meeting the hygiene requirements of food production. The volume of the filling cylinder 21 can be designed and selected according to the actual filling amount of bread 12 in production to meet the production needs of different products.

[0020] As attached Figure 1 and Figure 2 As shown, the filling cylinder 21 is positioned above the conveyor belt 11 and can move horizontally left and right, with its direction and speed consistent with the conveyor belt 11. This synchronous movement design ensures that the filling cylinder 21 and the bread 12 remain relatively stationary during the filling process, preventing filling spillage or displacement due to relative movement, thus ensuring filling accuracy. To achieve stable horizontal movement of the filling cylinder 21, a sliding part 26 is slidably engaged with the smooth rod 24 on the outer side of the filling cylinder 21. The sliding part 26 uses a high-precision linear bearing, which has advantages such as low friction coefficient, smooth movement, and long service life, ensuring smooth operation of the filling cylinder 21 during horizontal movement without jamming. The smooth rod 24 is fixed to the back plate 13 via the mounting part 25. The smooth rod 24 is made of high-strength alloy steel and undergoes precision grinding to ensure its surface smoothness and straightness, providing precise guidance for the movement of the sliding part 26.

[0021] An outlet is located at the bottom of the filling cylinder 21 to extrude the filling onto the bread 12. An inlet is also located on the side of the filling cylinder 21 to draw filling from the filling container 4. To ensure unidirectional flow of the filling and prevent backflow, one-way valves are installed at both the outlet at the bottom of the filling cylinder 21 and the inlet on the side. These one-way valves are made of food-grade silicone, providing excellent sealing and elasticity. They open and close accurately under the action of the piston 22, ensuring that when drawing filling, the one-way valve at the inlet is open and the one-way valve at the outlet is closed, allowing the filling to smoothly enter the filling cylinder 21. When extruding filling, the one-way valve at the outlet is open and the one-way valve at the inlet is closed, ensuring precise extrusion of the filling onto the bread 12, effectively preventing backflow and improving the efficiency and accuracy of filling.

[0022] Piston 22 is mounted on the bottom surface of the placement frame 23. The outer diameter of piston 22 is precisely fitted with the inner diameter of filling cylinder 21, and the gap between them is controlled within a very small range to ensure good sealing and prevent filling leakage during suction and extrusion. Piston 22 is made of food-grade rubber, which has good elasticity and wear resistance, allowing it to move flexibly within filling cylinder 21 while ensuring a tight fit with the cylinder wall to guarantee normal suction and extrusion of filling.

[0023] As attached Figure 2 and Figure 3As shown, the placement frame 23 is a crucial component connecting the piston 22, the filling container 4, and the drive mechanism 3. Made of lightweight, high-strength alloy material, it effectively reduces its own weight while ensuring sufficient load-bearing capacity, thereby lowering the load on the drive mechanism 3 and improving the operating efficiency of the device. The placement frame 23 has a rational structural design, with dedicated installation positions for fixing the filling container 4 and related components connecting the drive mechanism 3. The filling container 4 is secured to the placement frame 23 using bolts or clips, ensuring a firm and reliable installation that will not loosen or shift during device operation.

[0024] The filling container 4 is mounted on the placement rack 23 and is mainly used to supply filling to the filling cylinder 21. Its structural design fully considers the stability and continuity of filling supply. The filling container 4 is made of transparent food-grade plastic, making it easy for operators to observe the remaining amount of filling in the container and replenish it in a timely manner. The volume of the filling container 4 is reasonably designed and is usually small, serving only as a transitional supply. This design has two main advantages: First, it can reduce the overall weight of the placement rack 23, reduce the load on the drive mechanism 3 when driving the placement rack 23, reduce energy consumption, and also help improve the flexibility and stability of the placement rack 23's movement, ensuring accuracy during movement; second, the smaller volume of the filling container 4 allows for rapid turnover of the filling in the container, preventing the filling from spoiling or deteriorating in taste due to prolonged storage in the container, thus ensuring the freshness of the filling.

[0025] To achieve a stable and continuous feeding, a large hopper (not shown in the figure) can be connected to the filling hopper 4. The large hopper is typically located beside or above the device, and its volume is much larger than that of the filling hopper 4, capable of storing a large amount of filling. The large hopper is connected to the filling hopper 4 via a food-grade hose and is equipped with a flow control valve. This valve automatically adjusts the feeding speed based on the remaining amount of filling in the filling hopper 4, ensuring that a certain amount of filling is always maintained in the filling hopper 4, preventing any interruption in feeding. This guarantees that the filling mechanism 2 can continuously and stably supply filling to the filling cylinder 21, meeting the needs of continuous production. At this time, the freshness of the filling in the large hopper needs to be monitored.

[0026] As attached Figure 3As shown, in addition, a stirrer (not shown in detail in the figure) is also provided inside the filling container 4. The stirrer is mainly set up to prevent the filling from settling, separating, or clumping in the container, ensuring the uniformity of the filling and thus guaranteeing a consistent taste of the filling filled into the bread 12. The stirrer operates through the meshing of the driven gear 51 and the driving gear 52. The driving gear 52 is coaxially connected to the mounting shaft 32 in the drive mechanism 3. When the mounting shaft 32 rotates under the drive of the drive mechanism 3, it synchronously drives the driving gear 52 to rotate. The driving gear 52 then drives the driven gear 51 to rotate through meshing, thereby driving the stirrer to rotate and stir inside the filling container 4. This transmission method has a simple structure, high transmission efficiency, and stable operation, ensuring that the speed of the stirrer matches the operating rhythm of the drive mechanism 3, achieving continuous and uniform stirring of the filling, and effectively improving the quality of the filling.

[0027] As attached Figure 3 As shown, the drive mechanism 3 is the core component that provides power to the filling mechanism 2. It mainly drives the placement rack 23 and the piston 22 mounted on the placement rack 23 to perform horizontal and vertical movements above the conveyor belt 11. Through the coordinated action of these two movements, the piston 22 can push the filling cylinder 21 to move horizontally, keeping it relatively stationary with respect to the bread 12, and then move it up and down inside the filling cylinder 21, thereby completing the suction and extrusion of the filling. The drive mechanism 3 mainly includes a drive disc 31, a mounting shaft 32, an adapter arm 33, a connecting shaft 34, a ring sleeve 35, and a connecting arm 36. The precise connection and movement coordination between these components ensure the accuracy and stability of power transmission.

[0028] The drive mechanism 3 has two drive discs 31, which are symmetrically arranged and installed on the same side of the back plate 13. The drive discs 31 are made of high-strength cast iron or alloy steel, which have good wear resistance and fatigue resistance, and can withstand torque and impact during long-term operation.

[0029] A mounting shaft 32 is eccentrically mounted on the surface of each drive disc 31. The mounting shaft 32 is fixed to the drive disc 31 by an interference fit or key connection to ensure that the two can rotate synchronously. There is a certain eccentricity between the axis of the mounting shaft 32 and the axis of the drive disc 31. The size of this eccentricity directly affects the stroke of the subsequent lifting movement of the placement rack 23, and can be designed and adjusted according to the lifting requirements of the piston 22 in the filling cylinder 21. The mounting shaft 32 passes through the back plate 13 and is connected to the back plate 13 by a bearing, which allows the mounting shaft 32 to rotate flexibly, while ensuring that the mounting shaft 32 does not generate radial runout during rotation, thus ensuring the stability of power transmission.

[0030] One of the drive disks 31 is driven by a motor (not shown in the figure) mounted on the back plate 13, and the motor output shaft is coaxially arranged with the corresponding mounting shaft 32 of the drive disk 31. The motor is a servo motor, which has the advantages of high control precision, stable operation, and fast response speed. The motor output shaft is directly connected to the drive disk 31, which can directly transmit power to the drive disk 31. At the same time, since the motor output shaft is coaxial with the mounting shaft 32, the deviation and energy loss in the power transmission process can be minimized, and the rotation speed and rotation angle of the drive disk 31 and the mounting shaft 32 can be precisely controlled, providing accurate and stable power output for the entire drive mechanism 3. Since the mounting shaft 32 is fixedly connected to the drive disk 31, when the drive disk 31 rotates under the drive of the motor, it will synchronously drive the mounting shaft 32 to rotate. Furthermore, since the two drive disks 31 are connected by the subsequent ring 35 and connecting arm 36, when one drive disk 31 and its corresponding mounting shaft 32 rotate, it will drive the other drive disk 31 and its corresponding mounting shaft 32 to rotate synchronously, ensuring that the rotation speed and phase of the two drive disks 31 are completely consistent, providing a solid guarantee for the smooth movement of the subsequent placement frame 23.

[0031] After passing through the back plate 13, the mounting shaft 32 is fixedly connected at its end to the head end of the adapter arm 33. The adapter arm 33 is made of high-strength alloy material, possessing good rigidity and toughness, capable of bearing the weight of the mounting frame 23 and related components, and transmitting the power generated by the drive disc 31. The head end of the adapter arm 33 is fixed to the mounting shaft 32 by bolts or welding to ensure a firm and reliable connection, preventing loosening or breakage during power transmission.

[0032] The end of the adapter arm 33 is hinged to the placement frame 23 via a connecting shaft 34. The connecting shaft 34 is a high-strength pin with a hardened surface to improve wear resistance and strength. Both the end of the adapter arm 33 and the placement frame 23 have shaft holes that mate with the connecting shaft 34. After the connecting shaft 34 passes through these shaft holes, both ends are secured with snap rings or nuts to prevent it from falling off during movement. This hinged connection allows relative rotation between the adapter arm 33 and the placement frame 23. When the drive disc 31 drives the mounting shaft 32 in a circular motion, the adapter arm 33 swings accordingly, thereby pushing the placement frame 23 to achieve lifting and horizontal movement via the connecting shaft 34.

[0033] To ensure that the two drive discs 31 can always rotate synchronously, a ring sleeve 35 is rotatably fitted onto the outer ring surface of each drive disc 31. The ring sleeve 35 is made of wear-resistant material, and its inner diameter is precisely matched with the outer diameter of the drive disc 31. The two can rotate flexibly while ensuring that there is no excessive gap, thus avoiding shaking during operation.

[0034] The two rings 35 are connected by a connecting arm 36. The connecting arm 36 is also made of high-strength alloy material, and its two ends are fixedly connected to the two rings 35 respectively. The connection method can be welding or bolting. The length of the connecting arm 36 is precisely calculated to ensure that the two rings 35 can always remain on the same horizontal plane. During the rotation of the drive disk 31, the connecting arm 36 can drive the two rings 35 to move synchronously, thereby further enhancing the synchronization of the two drive disks 31 and the mounting shaft 32. This avoids unstable movement or jamming of the placement frame 23 due to asynchronous rotation, and ensures that the drive mechanism 3 can stably and reliably drive the filling mechanism 2.

[0035] When the motor drives one of the drive disks 31 to rotate, the drive disk 31 synchronously drives the mounting shaft 32, which is fixedly connected to it, to perform a circular motion (because the motor output shaft and the mounting shaft 32 are coaxial, the rotational accuracy of the drive disk 31 and the mounting shaft 32 is highly consistent). Since the mounting shaft 32 is fixedly connected to the head end of the adapter arm 33, the circular motion of the mounting shaft 32 is converted into the swing motion of the adapter arm 33. During the swinging process, the end of the adapter arm 33 pushes the placement rack 23 to move through the connecting shaft 34. At the same time, since the two drive disks 31 are connected by the ring 35 and the connecting arm 36, the other drive disk 31 and its corresponding mounting shaft 32 will also rotate synchronously under the drive of the connecting arm 36, and its corresponding adapter arm 33 will also push the placement rack 23 to move in the same way.

[0036] During the movement of the placement rack 23, due to the eccentric setting of the mounting shaft 32 relative to the drive disk 31, the placement rack 23 can simultaneously achieve horizontal and vertical movement: when the mounting shaft 32 rotates with the adapter arm 33 and approaches the conveyor belt 11, the adapter arm 33 pushes the placement rack 23 downward. At this time, the piston 22, driven by the placement rack 23, descends into the filling cylinder 21, reducing the space inside the filling cylinder 21, increasing the pressure, closing the one-way valve at the inlet, and opening the one-way valve at the outlet. The filling is squeezed out through the outlet at the bottom of the filling cylinder 21 onto the bread 12 on the conveyor belt below. When the adapter arm 33 rotates away from the conveyor belt 11, the adapter arm 33 pulls the placement rack 23 upward, and the piston 22 rises accordingly towards the outside of the filling cylinder 21. The space inside the filling cylinder 21 increases, creating negative pressure. The one-way valve at the outlet closes, and the one-way valve at the inlet opens, and the filling bucket 4... The filling is drawn into the filling cylinder 21 under negative pressure, thus replenishing the filling. Simultaneously, throughout the entire process, because the filling cylinder 21 slides against the guide rod 24 via the sliding part 26, and the drive mechanism 3 is designed so that the horizontal movement speed of the placement rack 23 matches the running speed of the conveyor belt 11, the filling cylinder 21 can remain relatively stationary with respect to the bread 12, ensuring that the filling is accurately and evenly filled into the bread 12.

[0037] In summary, this utility model device mainly consists of a frame 1, a filling mechanism 2, and a drive mechanism 3, enabling automated and precise filling of bread 12. The frame 1 provides stable support for the device, and the conveyor belt 11 on it has an adjustable speed and is synchronized with the filling mechanism 2 to ensure precise positioning of bread 12. The filling mechanism 2 includes a filling cylinder 21, a piston 22, a placement rack 23, and a filling bucket 4. The filling cylinder 21 moves smoothly through a sliding part 26 in cooperation with a smooth rod 24, and a one-way valve ensures unidirectional flow of filling. The filling bucket 4 serves as a transitional feeding mechanism, with an external large hopper for continuous feeding. An internal stirrer prevents filling from clumping and improves filling quality. The drive mechanism 3 is the core power source, driving the drive disk 31 via a servo motor. The motor output shaft is coaxial with the mounting shaft 32, reducing power loss and deviation. The two drive disks 31 are synchronized via the ring sleeve 35 and the connecting arm 36, driving the mounting shaft 32 and the adapter arm 33 to achieve horizontal and vertical movement of the placement rack 23, thereby allowing the piston 22 to complete the filling suction and extrusion. Through the coordinated work of the above mechanisms, the automatic bread filling filling device can achieve automated and precise filling of bread fillings, effectively improving the efficiency and quality of bread production, reducing labor costs, and meeting the needs of large-scale and continuous production in the modern food industry.

[0038] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
