[0031] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] See also Figures 1-4A continuous feeding device for a steamed bun packaging machine includes a frame 1, a conveyor 2 is installed on the frame, the conveyor 2 includes a double-row endless conveyor chain 7 rotatably mounted on the frame, wherein the conveyor also includes a driving sprocket and a driven sprocket rotatably mounted on the frame, the double-row conveyor chain is installed on the driving sprocket and the driven sprocket, and a chain tensioning mechanism 18 is installed on the frame corresponding to the driven chain position; conveyor chain plates 8 are evenly distributed axially between the double-row endless conveyor chains, and positioning plates 1 9 and 10 are respectively installed upward at the two ends of the conveyor chain plates on the frame, a conveying trough for storing steamed buns is formed between the positioning plate 1, the positioning plate 2 and the conveyor chain plate, the positioning plate 1 is installed on the conveyor chain plate, and the positioning plate 2 can be flipped and installed at the other end of the conveyor chain plate, and a flip frame 13 is installed on the back of the frame corresponding to the positioning plate 2. A rotating shaft 14 is installed on the top, which is rotatably installed between the double-row ring conveyor chains. A limiting mechanism 11 is installed on the flip frame away from the positioning plate 2. The limiting mechanism 11 is used to ensure the position of the positioning plate 2 during the conveying process; wherein the limiting mechanism includes a limiting rail installed on the frame, the limiting rail 16 is "L" shaped, and the bending portion 17 of the limiting rail is installed at the conveyor outlet position. A limiting bearing 15 that cooperates with the limiting rail is rotatably installed on the flip frame, and the limiting bearing cooperates with the rolling support of the limiting rail; when the steamed buns are transported to the outlet position, due to the action of the limiting rail, the positioning plate 2 maintains a continuous downward pushing action, pushing the steamed buns to the subsequent packaging line; the above design has the following advantages: (1) Improved flipping stability: The "L" shape design of the limiting rail 16 ensures the stability of the flip frame during the flipping process. When the flip frame rotates to a specific position (such as the conveyor outlet), the limiting bearing will roll along the bending portion of the limiting rail, thereby limiting the further movement of the flip frame. This design effectively prevents the overturning frame from overturning or shaking due to inertia or external force, and improves the stability and accuracy of the overturning. (2) Reduce wear and noise: The rolling support of the limit bearing and the limit rail reduces the friction and wear between the two. Compared with the traditional sliding contact method, the rolling contact method has a lower friction coefficient and a longer service life. At the same time, rolling contact also reduces the noise level caused by friction and improves the working environment. (3) Simplify overturning control: The design of the limit rail and the limit bearing simplifies the control process of the overturning frame. By rationally designing the shape and position of the limit rail, the overturning angle and stop position of the overturning frame can be accurately controlled. This design makes the overturning operation simpler and more reliable, and reduces the skill requirements for the operator. (4) Enhance equipment reliability: As an important support and limiting component of the overturning frame, the stability and reliability of the limit mechanism directly affect the operation effect of the entire equipment. The design of the "L"-shaped limit rail and limit bearing improves the stability and reliability of the limit mechanism, thereby enhancing the operation stability and reliability of the entire equipment. (5) Easy maintenance and adjustment: The installation and maintenance of the limit rail and the limit bearing are relatively simple.When necessary, worn parts can be easily inspected and replaced, or the position and angle of the limit rails and limit bearings can be adjusted. This design reduces maintenance costs and time, improving the maintainability and adjustability of the equipment. In summary, the limit mechanism, which utilizes an "L"-shaped limit rail mounted on the frame and is combined with the limit bearing rolling support on the turning frame, is a preferred solution for the continuous feeding device of a steamed bun packaging machine. This design improves turning stability, reduces wear and noise, simplifies turning control, enhances equipment reliability, and facilitates maintenance and adjustment, providing a more reliable and efficient solution for continuous and stable feeding of steamed buns.

[0033] A side clamping mechanism 5 is installed on the frame 1 at positions on both sides of the upper conveying surface of the conveyor 2, wherein the side clamping mechanism includes a side support roller group installed on both sides of the upper conveying surface of the conveyor, and the side support roller group includes a plurality of support rollers 12 installed side by side along the conveying direction, and the support rollers 12 are installed on the frame in an upward rotation; the above design has the following advantages: (1) Improved conveying stability: The side support roller group provides additional support and guidance for the steamed buns during the conveying process through a plurality of support rollers installed side by side along the conveying direction. These support rollers can effectively prevent the steamed buns from tipping over or deflecting during the conveying process, thereby improving the conveying stability. (2) Reduced steamed bun damage: Compared with the traditional clamping mechanism, the side support roller group contacts the steamed buns in a rolling contact manner, reducing the direct clamping force on the steamed buns. This design can reduce the extrusion and friction of the steamed buns during the conveying process, reduce the damage and deformation of the steamed buns, and ensure the integrity and aesthetics of the steamed buns. (3) Reduced noise and vibration: The rolling contact method of the side support roller group also helps to reduce the noise and vibration during the operation of the equipment. Compared with the traditional clamping mechanism, the rolling motion of the support roller is more stable and smooth, reducing the noise and vibration caused by uneven clamping force or loose clamping mechanism. (4) Strong adaptability: The design of the side support roller group has a certain flexibility and can be adjusted according to the size and shape of the steamed buns. By replacing support rollers of different diameters or spacings, it can adapt to the packaging needs of steamed buns of different types and sizes, improving the adaptability and flexibility of the equipment. (5) Easy maintenance: The maintenance of the side support roller group is relatively simple. When necessary, the worn support rollers can be easily disassembled and replaced, or the position and angle of the support rollers can be adjusted. This design reduces maintenance costs and time, and improves the reliability and service life of the equipment.

[0034] As a preferred embodiment, loading platforms 6 are also installed on the frame 1, corresponding to positions on both sides of the conveyor 2. The presence of the loading platforms makes the steamed bun loading process smoother and more efficient. Operators can directly place the steamed buns on the platforms, which automatically or with assistance feed them onto the conveyor, reducing manual handling and placement time, thereby improving overall production efficiency.

[0035] As a preferred embodiment, a track plate 19 is installed on the frame 1 at positions corresponding to the double-row endless conveyor chain 7. Guide and limit grooves are installed on the track plate at positions corresponding to the upper and lower conveying surfaces of the double-row endless conveyor chain, which cooperate with the double-row endless conveyor chain. This design enhances conveying stability: the guide and limit grooves ensure that the double-row endless conveyor chain maintains a stable trajectory and posture during operation. This helps reduce conveying instability caused by conveyor chain sway or deviation, thereby improving the stability and safety of steamed bun conveying.

[0036] As a preferred embodiment, a conveyor trough 4 is installed on the frame at the position corresponding to the discharge port of the conveyor, and a clamping belt mechanism 3 is installed on the frame at a position corresponding to the upper portion of the conveyor trough 4. The clamping belt mechanism 3 includes a support frame 301 rotatably mounted on the frame, and a plurality of belt rollers 302 are rotatably mounted on the support frame. The plurality of belt rollers are arranged in an inverted T shape, and a clamping belt 303 is wound around the belt roller. The clamping belt and the conveyor trough below form a clamping conveying channel, wherein the height of the clamping belt mechanism can be adjusted. This design can ensure that the steamed buns are stably and continuously conveyed at the discharge port. The clamping belt applies a certain clamping force to the steamed buns to prevent them from shifting or falling during the conveying process, thereby improving the conveying efficiency. The clamping action between the clamping belt and the conveyor trough is relatively gentle, which reduces the impact and extrusion on the steamed buns during the conveying process and helps to protect the integrity and appearance quality of the steamed buns.

[0037] As a preferred embodiment, the position of the conveying trough 4 can be moved perpendicular to the conveying direction. A guide rail 401 is installed on the frame along the direction of movement of the conveying trough, a slide 402 is installed on the guide rail, the conveying trough is installed on the slide, and a linear reciprocating drive mechanism 403 for driving the slide to move along the guide rail is installed on the frame; the conveying trough can be moved perpendicular to the conveying direction. This design enables the equipment to adapt to the packaging needs of steamed buns of different sizes and specifications. By adjusting the position of the conveying trough, it can be ensured that the steamed buns can accurately enter the subsequent packaging process, which improves the adaptability and flexibility of the equipment. The mobility of the conveying trough also allows for more flexible layout adjustments of the production line. According to the actual situation of the production site, the position and angle of the conveying trough can be easily adjusted to optimize the production process and improve production efficiency. The guide rails are protrudingly installed on both sides, and the bottom of the slide is rotatably installed with rollers 405 that cooperate with the guide rails. The above design has the following advantages: (1) It can reduce wear: the guide rails protruding on both sides of the guide rails cooperate with the rollers at the bottom of the slide. This rolling contact method reduces friction and wear and extends the service life of the equipment. At the same time, the guide column also plays a guiding and positioning role, ensuring the stability and accuracy of the conveyor trough during movement. (2) Simplified maintenance: The design of the guide rails, guide columns and rollers is relatively simple, easy to maintain and replace. When necessary, worn parts can be easily inspected and replaced, reducing maintenance costs and time.
