Description

Technical Field

[0001] This utility model relates to the technical field of steamed bun production equipment, specifically to a conveying mechanism for steamed bun production. Background Technology

[0002] In the modern food industry, steamed buns, as a traditional Chinese staple food, are widely loved by consumers due to their rich nutrition, unique flavor, portability, and convenience. With the growth of market demand and the rapid development of the food industry, the production process of steamed buns has gradually shifted from traditional manual production to mechanization and automation. Currently, the automated production process of steamed buns mainly includes multiple steps such as dough mixing, kneading, dough preparation, filling, shaping, proofing, and steaming. Conveying mechanisms are typically used to transport the buns between each step, and even within individual steps, to achieve continuous and integrated operations, thereby improving production efficiency and ensuring consistent product quality.

[0003] In actual production, in order to increase production capacity, many steamed bun production equipment adopts a multi-channel parallel processing structure, that is, multiple workstations operate on different steamed buns at the same time. For example, in the forming process, one machine may complete the forming of multiple steamed buns at the same time; therefore, in the conveying process, multiple parallel conveying mechanisms are often set up to carry steamed buns from different forming workstations and convey them to the subsequent proofing or steaming processes.

[0004] However, in multi-channel steamed bun production equipment, differences in processing time between channels or inconsistent response speeds can cause discrepancies in the time and position of the steamed buns as they arrive at the next processing step, resulting in a "positional asynchrony" problem. This phenomenon leads to the following issues:

[0005] 1. Affects subsequent uniform processing efficiency: For example, if the buns are not neatly arranged or arrive at the designated position simultaneously before entering the steamer, the steamer will be unevenly covered, affecting the uniformity of heat conduction, and thus affecting the steaming efficiency and finished product quality of the buns.

[0006] 2. Increased need for manual intervention: To solve the problem of uneven bun arrangement, it is often necessary to manually adjust the position of the buns. This not only increases labor intensity but also reduces the overall level of automation and affects production efficiency.

[0007] Therefore, there is an urgent need for a conveying mechanism for steamed bun production to solve the problem of asynchronous positions during multi-channel steamed bun conveying, so as to improve production efficiency and ensure the quality of finished products. Utility Model Content

[0008] The present invention aims to provide a conveying mechanism for steamed bun production, so as to solve the technical problem that the asynchronous position of steamed buns during multi-channel conveying affects the efficiency of subsequent uniform processing.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A conveying mechanism for producing steamed buns includes a frame, a controller, a conveying component, and a tidying component. Both the conveying component and the tidying component are mounted on the frame and are electrically connected to the controller. The number of conveying components is at least two, and all conveying components are arranged side by side. The tidying component includes a detection section and a tidying section. The detection section is used to detect whether a steamed bun is close to or has reached the tidying section, and the tidying section is used to arrange the steamed buns on all the conveying components neatly.

[0011] The principles and advantages of this scheme are:

[0012] In practical applications, the inspection department is responsible for monitoring whether the buns are close enough to reach the arranging department, which in turn is responsible for arranging all the buns on the conveyor components neatly. In this way, even if buns from different channels have deviations in arrival time and position, they can be adjusted to the designated position, ensuring a uniform state before entering the next process, thus achieving the following technical effects:

[0013] 1. Improve steaming efficiency and finished product quality: The neat assembly ensures that the buns can enter the steamer in an orderly manner, avoiding uneven heat conduction caused by uneven fabric, thereby improving steaming efficiency and the quality of the final product.

[0014] 2. Reduced manual intervention: The automated neat arrangement function reduces the need for manual adjustments, lowers labor intensity, and also improves the automation level and operating efficiency of the entire production line.

[0015] 3. Enhanced production consistency: Effectively solves the problem of asynchronous positions during multi-channel transmission, ensuring the consistency of each bun when entering subsequent processes, which helps maintain the stability of product quality.

[0016] 4. Enhanced flexibility and scalability: The multiple conveying components used in this solution can be controlled independently, making it easy to adjust the production scale or process flow according to actual needs, thus enhancing the flexibility and scalability of the equipment.

[0017] Preferably, as an improvement, the tidying part includes a drive cylinder fixedly connected to the frame and a drive rod rotatably connected to the frame. The drive rod is fixedly connected to the output shaft of the drive cylinder, and a tidying plate is fixedly connected to the drive rod. The drive cylinder is used to drive the tidying plate to rotate, so that the tidying plate is parallel or perpendicular to the conveying component. When the tidying plate is perpendicular to the conveying component, the distance between the bottom of the tidying plate and the conveying component is less than the height of the bun.

[0018] Beneficial effects: In this solution, the driving cylinder is used to drive the driving rod to rotate, thereby causing the tidying plate to rotate, enabling it to switch between working and non-working states: when the tidying plate is parallel to the conveying component, it is in a non-working state and does not affect the normal conveying of buns; when the tidying plate is perpendicular to the conveying component, it is in a working state, at which time the distance between the bottom of the tidying plate and the conveying component is less than the height of the buns, thus enabling it to block and organize the buns, making them neatly arranged.

[0019] Therefore, when buns on multiple conveying components are misaligned due to different arrival times, the aligning plate is set perpendicular to the conveying direction and works in conjunction with the conveying components. By using its height to be lower than the top of the buns, it limits and neatly moves the buns, thereby effectively correcting the positional deviation of the buns in each channel.

[0020] In addition, this solution adopts a linkage structure of cylinder-connecting rod-aligning plate, which has the advantages of compact structure, stable operation and fast response speed. It is suitable for high-speed continuous operation environment and is easy to maintain.

[0021] Preferably, as an improvement, the detection unit includes a mounting rod fixedly connected to the frame, with at least two sensors fixedly connected to the mounting rod. The sensors are arranged one-to-one above the conveying assembly, and the distance between the bottom of the sensor and the conveying assembly is greater than the height of the bun. The sensors are located upstream of the aligning plate, and the distance between the sensor and the aligning plate is less than the diameter of the bun. When any sensor detects that the distance between itself and the bun on the corresponding conveying assembly reaches a preset value, the drive cylinder drives the aligning plate to rotate perpendicular to the conveying assembly. When all sensors detect that the bun on the corresponding conveying assembly is below themselves, the drive cylinder drives the aligning plate to rotate parallel to the conveying assembly.

[0022] Beneficial effects: When any sensor detects that the distance between itself and the bun being conveyed on its corresponding conveying component reaches a preset value, the controller triggers the drive cylinder to rotate the aligning plate to a state perpendicular to the conveying component, entering the working position; when all sensors detect that their respective buns have completely passed the sensors and are below them, the controller controls the drive cylinder to reset, rotating the aligning plate back to a state parallel to the conveying component, exiting the working position.

[0023] This solution uses sensors to monitor the buns on each conveyor channel in real time, accurately determining their running status and relative position. This allows for the initiation of a neat arrangement process at the appropriate time, ensuring that multiple buns are synchronized in time and space, and significantly improving the consistency of the arrangement.

[0024] In addition, the sensors are positioned upstream of the tidying board and maintain a safe distance from the buns, which ensures the accuracy of the detection and avoids frequent start-stop of the tidying board due to misjudgment, thereby improving the stability and reliability of the equipment operation.

[0025] Preferably, as an improvement, the conveying assembly includes a conveying section, which includes a drive motor fixedly connected to the frame and an active roller and a driven roller rotatably connected to the frame. The active roller is coaxially and fixedly connected to the output shaft of the drive motor, and a conveyor belt is tensioned and connected to the active roller and the driven roller.

[0026] Beneficial effects: This solution uses a drive motor to power the active roller, which in turn drives the conveyor belt to circulate, achieving stable transport of the buns. It employs a classic motor-roller-belt transmission method, which is structurally mature, operates stably, is easy to manufacture and maintain, and is suitable for continuous production environments. Furthermore, the smooth surface of the conveyor belt and its stable operation effectively prevent the buns from tilting, falling, or deforming during transport, ensuring product quality.

[0027] Preferably, as an improvement, the conveying unit further includes at least one tensioning roller, and the conveyor belt is also tensioned and connected to the tensioning roller.

[0028] Beneficial Effects: This solution applies appropriate tension to the conveyor belt by installing tension rollers, maintaining stable tension during operation. The tension rollers effectively prevent belt slackness, misalignment, or slippage during operation, ensuring smooth and continuous operation and improving conveying reliability. Furthermore, by properly adjusting the tension, premature damage caused by excessive wear or deformation of the belt can be reduced, thereby extending its service life and lowering maintenance frequency and costs. In addition, the tension rollers ensure good contact between the conveyor belt and the driving and driven rollers, improving power transmission efficiency and making the bun conveying more uniform and smooth.

[0029] Preferably, as an improvement, the conveying assembly includes at least two conveying sections connected end to end, with the tidying assembly positioned above the downstream conveying section.

[0030] Beneficial effects: This solution achieves continuous and stable transport of buns through multiple conveyor sections, and the tidying component is positioned above the downstream conveyor section, allowing the buns to be automatically tidied before entering the next process (such as proofing or steaming). The operation of multiple conveyor sections can be controlled independently, facilitating the adjustment of the conveying rhythm of each section and ensuring smoother and more stable transfer of buns between different workstations, reducing impact and deviation. Furthermore, placing the tidying component above the downstream conveyor section ensures that the buns complete the tidying process before entering critical processing steps, improving arrangement consistency and facilitating uniform fabric distribution and heat treatment.

[0031] Preferably, as an improvement, the conveying assembly further includes a limiting part, which includes several pairs of limiting blocks arranged along the conveying direction. Each pair of limiting blocks is symmetrically arranged on both sides of the conveyor belt to limit the conveyor belt.

[0032] Beneficial Effects: This solution effectively constrains both sides of the conveyor belt using limit blocks, ensuring stable operation along the set path. The limit blocks provide real-time control of both sides of the conveyor belt, effectively preventing lateral deviation due to uneven tension, installation errors, or external interference during operation, thus ensuring the continuity and stability of the conveying process. Furthermore, once the belt runs stably, the positional deviation of the buns during conveying decreases, which helps improve the accuracy of subsequent inspection and sorting operations, further enhancing the automation level of the entire production line and product quality. In addition, the constraint effect of the limit blocks reduces abnormal friction between the belt and the rollers, minimizing wear and damage caused by belt misalignment, thereby extending the belt's service life.

[0033] Preferably, as an improvement, the limiting block is inverted L-shaped, with the vertical part of the limiting block perpendicular to the working surface of the conveyor belt, and the horizontal part of the limiting block located above the conveyor belt and parallel to the working surface of the conveyor belt.

[0034] Beneficial Effects: This solution achieves dual limiting functions for both the conveyor belt and the buns using an inverted L-shaped limiting block. The inverted L-shaped structure provides stable lateral support to the conveyor belt in the vertical direction, preventing belt deviation; simultaneously, its horizontal portion extends above the belt, providing slight constraint on both sides of the buns to prevent tilting or lateral displacement during transport, thus improving the stability of the conveying process. Furthermore, the horizontal portion of the limiting block is located above and parallel to the conveyor belt, effectively limiting and guiding the buns during their movement. This is particularly suitable for small-sized or easily rolling buns, effectively preventing them from falling or deviating from the predetermined path during transport.

[0035] Preferably, as an improvement, the surface of the frame is provided with a housing, the housing has a feed port at the position corresponding to the feed end of the conveying component, and the housing has a discharge port at the position corresponding to the discharge end of the conveying component, the feed end and discharge end of the conveying component extend out of the housing through the feed port and discharge port respectively.

[0036] Beneficial Effects: This solution uses a casing to enclose and protect the main components of the conveying mechanism, while rationally arranging the inlet and outlet to ensure smooth entry and exit of buns from the conveying components. The casing effectively prevents external dust and impurities from entering the equipment, avoiding contamination or interference with the conveying components and control system, thus improving the safety and stability of equipment operation. This is particularly suitable for food processing environments with high hygiene requirements. Furthermore, the casing design makes the overall machine appearance cleaner and more aesthetically pleasing, while reducing safety hazards caused by exposed moving parts, creating a safer and more orderly production environment. In addition, the precise alignment of the inlet and outlet positions with the inlet and outlet ends of the conveying components facilitates seamless integration with other process equipment (such as forming machines and steamers), improving the overall automation level and continuous production capacity of the production line.

[0037] Preferably, as an improvement, the bottom of the frame is provided with a number of rollers.

[0038] Beneficial effects: This solution, by installing rollers at the bottom of the frame, gives the entire conveyor mechanism excellent mobility and positioning flexibility. The rollers allow the conveyor mechanism to be easily moved and repositioned within the workshop, facilitating flexible deployment according to the production line layout and improving the equipment's usability and on-site adaptability. Furthermore, during equipment installation, commissioning, or workstation changes, the rollers significantly reduce the difficulty of handling and positioning, reducing labor costs and improving work efficiency.

[0048] Example

[0049] This embodiment provides a conveying mechanism for steamed bun production, as shown in the attached figure. Figure 1 , Figure 2 and Figure 3 As shown, the system includes a frame 50, a controller, a conveying assembly 60, and a tidying assembly 70. Both the conveying assembly 60 and the tidying assembly 70 are mounted on the frame 50 and are electrically connected to the controller. In this embodiment, there are two conveying assemblies 60, arranged side-by-side. The controller is a conventional PLC controller.

[0050] A housing 51 is fixedly connected to the surface of the frame 50, forming a relatively enclosed environment. The conveying component 60 and the tidying component 70 are basically located inside the housing 51, reducing contamination during the bun conveying process. For convenient loading and unloading, the housing 51 has an inlet 511 corresponding to the feeding end of the conveying component 60, and an outlet 512 corresponding to the discharging end of the conveying component 60. The feeding and discharging ends of the conveying component 60 extend out of the housing 51 through the inlet 511 and outlet 512, respectively. Several rollers 52 are installed at the bottom of the frame 50 to facilitate moving the entire device to the corresponding processing position. In this embodiment, the rollers 52 are universal wheels with brakes. Universal wheels with brakes are mature existing technology, and their structure will not be described in detail in this embodiment.

[0051] The conveying assembly 60 includes two conveying sections 61 connected end-to-end, symmetrically arranged along the conveying direction. Each conveying section 61 includes a drive motor 611, a drive roller 613, a driven roller 614, and a conveyor belt 612. The drive motor 611 is fixedly connected to the frame 50 and electrically connected to a controller. Both the drive roller 613 and the driven roller 614 are rotatably connected to the frame 50, and one end of the drive roller 613 is coaxially fixedly connected to the output shaft of the drive motor 611 via a coupling. The conveyor belt 612 is tensioned and connected to the drive roller 613 and the driven roller 614. In this embodiment, the conveying section 61 also includes two tension rollers 615 rotatably connected to the frame 50, symmetrically arranged above and on both sides of the drive roller 613, and the conveyor belt 612 is also tensioned and connected to the two tension rollers 615.

[0052] The conveying assembly 60 also includes a limiting part, which comprises several pairs of limiting blocks 62 arranged along the conveying direction. All limiting blocks 62 are fixedly connected to the frame 50. Each pair of limiting blocks 62 is symmetrically arranged on both sides of the conveyor belt 612 to limit the movement of the conveyor belt 612. In this embodiment, the limiting block 62 is inverted L-shaped, that is, the limiting block 62 includes an integrally formed vertical part and a horizontal part. The vertical part of the limiting block 62 is perpendicular to the working surface of the conveyor belt 612, and the horizontal part of the limiting block 62 is located above the conveyor belt 612 and parallel to the working surface of the conveyor belt 612.

[0053] It should be noted that the working surface of the conveyor belt 612, that is, the horizontal part of the conveyor belt 612, is the plane that contacts the bun.

[0054] The tidying assembly 70 is disposed above the downstream conveyor section 61. The tidying assembly 70 includes a detection section 71 and a tidying section 72. The detection section 71 is used to detect whether the buns are close to and have reached the tidying section 72, and the tidying section 72 is used to tidy up the buns on the two conveyor sections 60.

[0055] The tidying unit 72 includes a drive cylinder 721, a drive rod 722, and a tidying plate 723. The drive cylinder 721 is electrically connected to the controller and is fixedly connected to the frame 50. Specifically, the drive cylinder 721 is a rotary cylinder. The drive rod 722 is rotatably connected to the frame 50, and one end of the drive rod 722 is coaxially fixedly connected to the output shaft of the drive cylinder 721 via a coupling. The axis of the drive rod 722 is perpendicular to the conveying direction. The tidying plate 723 is fixedly connected to the drive rod 722, and the tidying plate 723 is parallel to the axis of the drive rod 722. The drive cylinder 721 is used to drive the tidying plate 723 to rotate, so that the tidying plate 723 is parallel or perpendicular to the working surface of the conveyor belt 612. When the tidying plate 723 is perpendicular to the working surface of the conveyor belt 612, the distance between the bottom of the tidying plate 723 and the working surface of the conveyor belt 612 is less than the height of the bun.

[0056] The detection unit 71 includes a mounting rod 711 and two sensors 712. The mounting rod 711 is fixedly connected to the frame 50, and the two sensors 712 are fixedly connected to the mounting rod 711. Both sensors 712 are electrically connected to the controller. The two sensors 712 are positioned one-to-one above the conveyor belt 612, and the distance between the bottom of the sensor 712 and the working surface of the conveyor belt 612 is greater than the height of the bun. The sensor 712 is located upstream of the aligning plate 723, and the distance between the sensor 712 and the aligning plate 723 is less than the diameter of the bun. When any sensor 712 detects that the distance between itself and the bun on the corresponding conveyor belt 612 reaches a preset value, the drive cylinder 721 drives the aligning plate 723 to rotate perpendicular to the working surface of the conveyor belt 612; when all sensors 712 detect that the bun on the corresponding conveyor belt 612 is below itself, the drive cylinder 721 drives the aligning plate 723 to rotate parallel to the working surface of the conveyor belt 612.

[0057] This embodiment also provides a steamed bun pleating device, including the aforementioned conveying mechanism for steamed bun production, and further including a pleating mechanism. (See attached image) Figure 4 As shown, the number of pinching mechanisms is the same as the number of conveying components 60, and the pinching mechanisms are arranged one-to-one above the conveying components 60. In this embodiment, the pinching mechanism is located above the upstream conveying section 61 of the conveying component 60.

[0058] As attached Figure 5 , Figure 6 and Figure 7As shown, the pleating mechanism includes an overall moving component 10, a partial moving component 20, a pleating component 30, and a guide component 40. The partial moving component 20 is connected to the output end of the overall moving component 10, and the pleating component 30 is connected to the output end of the partial moving component 20. The overall moving component 10 drives the partial moving component 20 and the pleating component 30 to move synchronously in the vertical direction. The partial moving component 20 drives the pleating component 30 to move vertically. The pleating component 30 is used to pleat the top of the bun to form pleats. The guide component 40 guides the synchronous movement of the partial moving component 20 and the pleating component 30, as well as the individual movement of the pleating component 30.

[0059] The overall moving assembly 10 includes a mounting bracket 11, an overall motor 12, and an overall lead screw 13. The overall motor 12 is electrically connected to the controller. The overall motor 12 is vertically fixedly connected to the top of the mounting bracket 11, with the output shaft of the overall motor 12 facing downwards. The screw of the overall lead screw 13 is coaxially fixedly connected to the output shaft of the overall motor 12.

[0060] The local movement assembly 20 includes a mounting plate 21, a local motor 22, and a local lead screw 23. The local motor 22 is electrically connected to the controller. The mounting plate 21 is sleeved on the nut of the integral lead screw 13 and is fixedly connected to the nut of the integral lead screw 13. The mounting plate 21 is horizontally positioned, and the local motor 22 is vertically fixedly connected to the top of the mounting plate 21, with the output shaft of the local motor 22 passing downward through the mounting plate 21. The screw of the local lead screw 23 is coaxially fixedly connected to the output shaft of the local motor 22.

[0061] The pleating assembly 30 includes a connecting cylinder 31, which is coaxially and movably sleeved on the screw of the local lead screw 23, with the top of the connecting cylinder 31 fixedly connected to the bottom of the nut of the local lead screw 23. A mounting cylinder 32 is fixedly connected to the bottom of the connecting cylinder 31, and the mounting cylinder 32 is coaxially and movably sleeved on the screw of the local lead screw 23. A mounting ring 33 is coaxially and fixedly sleeved on the mounting cylinder 32, and several mounting posts 34 are fixedly connected to the bottom of the mounting ring 33, with the mounting posts 34 evenly distributed circumferentially. A pleating blade 35 is detachably and fixedly connected to the bottom of each mounting post 34 by bolts. The blade edges of all pleating blades 35 are located at the bottom, and the extended surfaces of all pleating blades 35 intersect on the same vertical line. The bottom of all pleating blades 35 is bent counterclockwise, and the included angle between the upper and lower parts of the pleating blade 35 after bending is an obtuse angle.

[0062] In this embodiment, the pleating assembly 30 further includes a limiting ring 36 coaxially fixedly sleeved on the mounting cylinder 32. The limiting ring 36 is located below the mounting ring 33, and a limiting groove is formed on the outer peripheral wall of the limiting ring 36 corresponding to the position of the pleating blade 35. The limiting groove penetrates the upper and lower end faces of the limiting ring 36, and the pleating blade 35 is inserted into the limiting groove at the corresponding position. The width of the limiting groove matches the thickness of the pleating blade 35, so that the limiting groove can limit the pleating blade 35 and prevent the pleating blade 35 from shaking when performing the pleating operation on the top of the bun.

[0063] The guide assembly 40 includes two guide rods 41 that are vertically fixedly connected to the mounting bracket 11. The mounting plate 21 has mounting holes corresponding to the positions of the guide rods 41, and the guide rods 41 are vertically slidably inserted into the mounting holes at the corresponding positions.

[0064] The guide assembly 40 also includes a partial guide plate 42, which is horizontally positioned and its top is fixedly connected to the bottom of the connecting cylinder 31. A connecting groove 43 is formed on the side of the partial guide plate 42 away from the mounting bracket 11, extending through the upper and lower end faces of the partial guide plate 42. The mounting cylinder 32 is vertically inserted into the connecting groove 43, and its outer wall is embedded and fixedly connected to the inner wall of the connecting groove 43. A partial guide hole is formed on the partial guide plate 42 corresponding to the position of the guide rod 41, and the guide rod 41 is vertically slidably inserted into the corresponding partial guide hole. In this embodiment, a clearance hole is formed on the partial guide plate 42 corresponding to the position of the screw of the integral lead screw 13, and the screw of the integral lead screw 13 is vertically and movably inserted into the clearance hole.

[0065] The guide assembly 40 also includes an integral guide plate 44, which is horizontally positioned below the partial guide plate 42. Two synchronization plates 45 are vertically fixedly connected between the integral guide plate 44 and the mounting plate 21. The integral guide plate 44 has integral guide holes corresponding to the positions of the guide rods 41, and the guide rods 41 are vertically slidably inserted into the integral guide holes at the corresponding positions. A clearance groove is formed on the side of the integral guide plate 44 away from the mounting bracket 11, and the clearance groove extends through the upper and lower end faces of the integral guide plate 44. The mounting ring 33 is vertically movably inserted into the clearance groove.

[0066] In this embodiment, a connecting plate 46 is fixedly connected to the top of the integral guide plate 44. A connecting hole is formed on the connecting plate 46 corresponding to the position of the mounting cylinder 32, and the connecting hole penetrates the upper and lower end faces of the connecting plate 46. The mounting cylinder 32 is vertically slidably inserted into the connecting hole. A guide ring 47 is fixedly connected to the top of the connecting plate 46, and the guide ring 47 is coaxially sleeved on the mounting cylinder 32. The outer wall of the mounting cylinder 32 slides against the inner wall of the guide ring 47. The mounting cylinder 32 is located below the connecting plate 46, and the outer diameter of the mounting cylinder 32 is larger than the diameter of the connecting hole, allowing the top of the mounting cylinder 32 to abut against the bottom of the connecting plate 46.

[0067] Two limiting cylinders 48 are vertically fixedly connected to the top of the overall guide plate 44. The limiting cylinders 48 are coaxially arranged with the overall guide hole, and the guide rod 41 is vertically slidably connected in the corresponding limiting cylinder 48. The limiting cylinders 48 can not only guide the overall guide plate 44 to move up and down along the guide rod 41, but also limit the minimum distance between the local guide plate 42 and the overall guide plate 44, so as to prevent the pleating assembly 30 from pleating the top of the bun too deeply.

[0068] The specific implementation process is as follows:

[0069] (1) Feeding: The conveying mechanism of the previous process conveys the buns to be pleated to the feeding end of the two conveying components 60. At this time, the buns to be pleated are located on the conveyor belt 612 of the upstream conveying section 61. The controller controls the drive motor 611 of the upstream conveying section 61 to start, so as to drive the drive roller 613 to rotate, thereby driving the conveyor belt 612 to move, and then the buns are conveyed through the feeding port 511 of the housing 51 to the bottom of the pleating mechanism and then the conveying is stopped.

[0070] (2) Pinch and Pleat: The controller starts the overall motor 12, which drives the screw of the overall lead screw 13 to rotate, causing the mounting plate 21 to move downwards along with the nut of the overall lead screw 13. This moves the local motor 22 and the pinching assembly 30 connected to the output shaft of the local motor 22 downwards until the bottom of the pinching blade 35 contacts the top of the bun. Then, the controller starts the local motor 22, which drives the screw of the local lead screw 23 to rotate, causing the pinching assembly 30 to move downwards along with the nut of the local lead screw 23. This presses the blade at the bottom of the pinching blade 35 into the top of the bun, completing the pinching and pleating operation.

[0071] (3) Conveying: After the pinching operation is completed, the controller first controls the local motor 22 to drive the screw of the local lead screw 23 to rotate in the opposite direction, thereby resetting the pinching assembly 30. Then, the controller controls the overall motor 12 to drive the screw of the overall lead screw 13 to rotate in the opposite direction, thereby resetting the local moving assembly 20 and the pinching assembly 30. Then, the controller controls the drive motor 611 of the upstream conveyor 61 and the drive motor 611 of the downstream conveyor 61 to start, driving the upstream and downstream conveyor belts 612 to move, so that the pinched buns are moved from the upstream conveyor belt 612 to the downstream conveyor belt 612.

[0072] (4) Neatness: Sensor 712 detects the distance between itself and the buns on the corresponding conveyor assembly 60 and sends a detection signal to the controller. When the detection signal sent by either sensor 712 indicates that the distance between the bun and itself reaches a preset value, the controller controls the drive cylinder 721 to start. The drive cylinder 721 drives the tidying plate 723 to rotate through the drive rod 722, so that the tidying plate 723 rotates from a state parallel to the working surface of the conveyor belt 612 to a state perpendicular to the working surface of the conveyor belt 612. Since the distance between the bottom of the tidying plate 723 and the working surface of the conveyor belt 612 is less than the height of the bun when the bun is conveyed to the tidying plate 723, the bun will be intercepted by the tidying plate 723. When the buns on both conveyor assemblies 60 are intercepted by the tidying plate 723, the buns on the two conveyor assemblies 60 can be neatly arranged by the tidying plate 723.

[0073] (5) Feeding: When the detection signals sent by both sensors 712 indicate that the bun is located below them, the controller controls the drive cylinder 721 to drive the drive plate to rotate in the opposite direction, thereby driving the tidying plate 723 to rotate in the opposite direction, so that the tidying plate 723 returns from a state perpendicular to the working surface of the conveyor belt 612 to a state parallel to the working surface of the conveyor belt 612. At this time, the bun can pass smoothly under the tidying plate 723, and the downstream conveyor 61 conveys the bun through the discharge port 512 of the housing 51 to the discharge end of the conveyor assembly 60, so as to transfer the pleated bun to the next process.
