Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a fully automatic steamed bun bagging and packaging machine. Background Technology

[0002] The fully automatic steamed bun bagging and packaging machine is an automated equipment that integrates automatic material handling, bagging, and sealing functions. Utilizing servo control and vision inspection technologies, it can accurately bag and package steamed buns and other pastries. It can adapt to products of different specifications, achieving highly flexible and high-speed production. It is mainly used in the food processing field, especially in the large-scale production of Chinese pastries such as steamed buns and mantou, helping enterprises improve packaging efficiency, ensure hygiene and quality, and covering various production scenarios from large food factories to small workshops.

[0003] The fully automatic steamed bun bagging and packaging machine mainly consists of feeding, packaging material supply, filling and sealing, control, conveying and discharging. Feeding involves transporting steamed buns via a conveyor belt, using sensors and guiding devices to arrange the buns neatly and accurately to the packaging station. Packaging material supply utilizes roll film to store packaging materials, which are then tractioned by a film feeding wheel and cut by a cutting device to provide formed packaging bags for steamed bun packaging. Filling and sealing rely on robotic arms and other actuators to feed the arranged steamed buns into the packaging bags, and then use heat sealing or cold sealing processes to seal the bag opening. Control is based on a PLC, combined with a touch screen operating interface and various sensors to monitor and adjust the equipment's operating parameters and processes in real time. Conveying and discharging are achieved through conveyor belts, chutes, and other structures to transport and discharge the packaged finished steamed buns from the equipment. These components work together to realize the complete process of automatic steamed bun bagging and packaging.

[0004] In existing technologies, due to the precision structure of the sealing cutter, it is often integrated with the heat sealing device and is located in a compact position. It is difficult to reach the blade seams and edges during manual cleaning, which easily leads to the residue of filling grease and packaging bag debris. Disassembly and cleaning require professional tools and techniques, which is cumbersome and time-consuming, affecting production efficiency. Repeated disassembly and cleaning also cause wear and tear on parts and a decrease in installation accuracy. In addition, there is a lack of an effective automatic cleaning mechanism during the cleaning process, making it difficult to remove residual impurities in real time. Long-term accumulation not only affects the sealing quality, causing problems such as poor sealing and bag damage, but also breeds bacteria, posing a food safety hazard. At the same time, residual dirt also accelerates the wear of the cutter, shortens its service life, and increases equipment maintenance costs. Therefore, a fully automatic bun bagging and packaging machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fully automatic bun bagging and packaging machine, which aims to improve the problem that the sealing cutter cannot be effectively cleaned in the existing technology, thus affecting the sealing quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A fully automatic steamed bun bagging and packaging machine includes a frame.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1 to 3 This utility model provides an embodiment of a fully automatic bun bagging and packaging machine, including a frame 1. Two protective shells 2 are fixedly connected to the outer wall of the frame 1. The protective shells 2 are used to protect the internal cleaning components and provide support for the nozzle 10 to move up and down. A motor 3 is fixedly connected to the outer wall of the protective shell 2. The motor 3 provides the power source for the operation of the nozzle 10. A gear 4 is fixedly connected to the drive end of the motor 3. The gear 4 rotates under the drive of the motor 3. It can rotate clockwise and counterclockwise, and can also rotate at different speeds. A rack 5 is slidably connected to the inner wall of the protective shell 2. The rack 5 can slide vertically inside the protective shell 2. The outer side of the gear 4 is meshed with the outer side of the rack 5. Through the meshing transmission of the gear 4 and the rack 5, the rotational motion of the motor 3 is converted into the linear reciprocating motion of the rack 5. A moving plate 6 is fixedly connected to the left side of the rack 5. The movement of the rack 5 will drive the moving plate 6 to move synchronously. A connecting rod 7 is fixedly connected to the outer wall of the moving plate 6. The movement of the moving plate 6 is transmitted to the shock-absorbing plate 8 through the connecting rod 7. A shock-absorbing plate 8 is fixedly connected to the outer wall of the connecting rod 7. The shock-absorbing plate 8 can absorb the low-frequency vibration transmitted by the motor 3 during operation. A support block 9 is fixedly connected to the outer wall of the shock-absorbing plate 8. The shock-absorbing plate 8 drives the support block 9 to move together. The support block 9 is used to install and support the nozzle 10. Multiple nozzles 10 are fixedly connected to the outer wall of the support block 9. The nozzles 10 are used to spray cleaning medium to clean the sealing cutter component. The indirect power transmission through the connecting rod 7 can effectively avoid the high-frequency vibration generated by the motor 3 from interfering with the nozzles 10. A limit plate 11 is fixedly connected to the rear side of the moving plate 6. The limit plate 11 moves with the moving plate 6 and limits and guides the entire vertical reciprocating motion. A limit rod 12 is fixedly connected to the inner wall of the protective shell 2. The limit plate 11 is slidably connected to the outer wall of the limit rod 12. The movement direction of the moving plate 6 is restricted by the cooperation of the limiting plate 11 and the limiting rod 12, ensuring that it moves smoothly along a straight line. The outer wall of the frame 1 is provided with a replacement assembly for replacing the sealing cutter. The front side of the limiting plate 11 is fixedly connected to the rear side of the rack 5, so that the limiting plate 11 and the rack 5 form a fixed connection and can move synchronously. The inner wall of the limiting plate 11 is slidably connected to the outer wall of the limiting rod 12. The limiting rod 12 guides and limits the sliding of the limiting plate 11, thereby improving the stability of the entire cleaning assembly when it is raised and lowered. The outer wall of the shock absorber 8 is slidably connected to the inner wall of the protective shell 2. The protective shell 2 provides support for the sliding of the shock absorber 8. The outer wall of the support block 9 is slidably connected to the inner wall of the protective shell 2. The protective shell 2 provides support for the sliding of the support block 9, ensuring that the movement of the support block 9 and the nozzle 10 is smooth.

[0013] Reference Figure 1 , Figure 2 and Figure 4The replacement component includes sliding rods 13, which are used to fix the knife holder 14 and provide guidance for the sliding of the sealing cutter 22. The outer walls of both sliding rods 13 are fixedly connected to the outer wall of the frame 1, and the sliding rods 13 are fixed on the frame 1 to provide an installation base for the replacement component. The front side of the two sliding rods 13 is detachably connected to the knife holder 14, which is used to install the sealing cutter. The detachable connection facilitates the replacement of the knife holder 14 and the sealing cutter. The outer wall of the knife holder 14 is rotatably connected to a rotating rod 15, which can rotate on the knife holder 14 to unlock and fix the knife holder 14. The rear side of the rotating rod 15 is fixedly connected to a limit block 16, which rotates with the rotating rod 15. The limit block 16 is used to install and remove the knife holder 14 through mutual cooperation with the sliding frame 17. One of the sliding rods 13 has a sliding frame 17 slidably connected to its front side. The sliding frame 17 can slide left and right. When the sliding frame 17 slides to the left, it installs and fixes the tool holder 14. When the sliding frame 17 slides to the right, it unlocks and removes the tool holder 14. A lever 18 is fixedly connected to the top of the sliding frame 17. The lever 18 is used for manual operation and can control the sliding frame 17 to slide to the right. The outer wall of the sliding frame 17 is slidably connected to the inner wall of the tool holder 14. The tool holder 14 provides support for the sliding of the sliding frame 17. One of the sliding rods 13 has a support plate 20 fixedly connected to its front side. The support plate 20 supports the spring 19 and provides a fixing point for it. The outer wall of the lever 18 is detachably connected to the inner wall of the tool holder 14. After the tool holder 14 is installed, the lever 18 can slide on the outer wall of the tool holder 14. Move the lever 18 to the right to move the sliding frame 17 to the right. After the knife holder 14 is removed, the lever 18 and the knife holder 14 are separated. A spring 19 is fixedly connected to the right side of the sliding frame 17. The spring 19 is used to provide a restoring force for the sliding frame 17, so that it is kept close to the limit block 16 without external force. The right side of the spring 19 is fixedly connected to the outer wall of the support plate 20. Fix one end of the spring 19 to the support plate 20 to ensure that the spring 19 can work normally. A sealing cutter 21 is fixedly connected to the outer wall of the knife holder 14. The sealing cutter 21 is fixed on the knife holder 14 and is used to cut and seal the packaging bag. A sealing cutter 22 is slidably connected to the outer wall of the sliding rod 13. The sealing cutter 22 can slide back and forth on the sliding rod 13 and is driven by a cylinder.

[0014] Working principle: When motor 3 rotates clockwise, its drive end drives gear 4 to rotate clockwise synchronously. Since gear 4 meshes with rack 5, rack 5 slides down along the inner wall of protective shell 2, and the moving plate 6 on the left moves down accordingly. The limiting plate 11 on the rear side of moving plate 6 slides down synchronously. At this time, the inner wall of limiting plate 11 slides along the outer wall of limiting rod 12 to ensure that moving plate 6 moves down smoothly in a straight line. Moving plate 6 drives shock absorber 8 to move down through connecting rod 7. Shock absorber 8 then drives support block 9 to move down, and finally makes multiple nozzles 10 on support block 9 move down synchronously. When motor 3 rotates counterclockwise, gear 4 rotates counterclockwise to drive rack 5 to slide up. The limiting plate 11 on the rear side of moving plate 6 slides up along limiting rod 12 for guidance. Through connecting rod 7, shock absorber 8, support block 9 and nozzles 10 move up in sequence. Thus, with the cooperation of limiting plate 11 and limiting rod 12, the vertical reciprocating cleaning motion of nozzles 10 is realized, which can effectively clean the sealing cutter component. During installation, the tool holder 14 is fitted onto the front side of the two sliding rods 13. The sliding frame 17 slides to the left under the restoring force of the spring 19, causing its outer wall to slide against the inner wall of the tool holder 14. Simultaneously, the rotating rod 15 is rotated clockwise. When the limiting block 16 rotates from the top position to the right position, it slides along the outer wall of the sliding frame 17 and presses it to slide to the right, causing the lever 18 to move to the right synchronously, compressing the spring 19. When the limiting block 16 slides into the groove of the sliding frame 17, the spring 19... When the sliding frame 17 is reset to the left, the lever 18 returns to its original position, completing the installation of the knife holder 14. To disassemble, move the lever 18 to the right, causing the sliding frame 17 to move to the right and compress the spring 19, separating the sliding frame 17 from the limiting block 16. Then, rotate the rotating rod 15 counterclockwise to release the limitation on the knife holder 14. After releasing the lever 18, the spring 19 causes the sliding frame 17 and the lever 18 to reset. At this point, the knife holder 14 can be removed from the sliding rod 13, thus disassembling the sealing cutter.

[0015] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
