Description

Technical Field

[0001] This invention relates to the field of food packaging equipment technology, and more particularly to a packaging equipment for bread production. Background Technology

[0002] Bread is a baked food made primarily from wheat flour, yeast, water, sugar, and salt, through processes such as kneading, fermentation, shaping, and baking. It has a soft texture and diverse flavors, and is a common staple food and snack in daily life. Bread packaging equipment is an automated mechanical device used for packaging bread. It can efficiently package bread, with common packaging methods including vacuum packaging and gas-flushing packaging. This equipment typically has functions such as automatic metering, bagging, sealing, and labeling, effectively maintaining the freshness of bread and extending its shelf life, while also improving the product's appearance and market competitiveness. It is widely used in the packaging production lines of bread manufacturing companies.

[0003] While existing packaging equipment for bread production can continuously package bread on conveyor belts, the packaging speed is usually constant. Therefore, workers need to place the bread at equal intervals on the conveyor belt, which is not only time-consuming and labor-intensive but also seriously affects worker efficiency and user experience. Furthermore, when using inflatable packaging equipment, existing packaging equipment leaves a lot of air inside the bags, which not only shortens the shelf life of the bread but also makes the packaged bread prone to swelling or even breaking at high temperatures, resulting in poor packaging effectiveness.

[0004] Based on the above, the present invention proposes a packaging equipment for bread production that is easy to use and has good packaging effect. Summary of the Invention

[0005] To overcome the shortcomings of existing bread production packaging equipment, which requires workers to place bread at equal intervals on the conveyor belt, is not only time-consuming and labor-intensive, but also seriously affects worker efficiency and user experience. Furthermore, the air-filled packaging process leaves excessive air inside the bags, which not only shortens the shelf life of the bread but also makes the packaged bread prone to swelling or even breaking at high temperatures, resulting in poor packaging performance, this invention provides a convenient and effective packaging device for bread production.

[0006] A packaging device for bread production includes a frame, a film winder, a protective shell, a heat-sealing assembly, a bottom-sealing assembly, a transport assembly, a hollow guide plate, a gas tank, a connecting pipe, a rotating frame, an electric slide rail, a movable frame, and an extrusion cylinder. The frame is equipped with a film winder, a protective shell is fixedly connected to the frame, a heat-sealing assembly is installed on the frame, a bottom-sealing assembly is installed on the frame, a transport assembly is installed on the frame, a hollow guide plate is fixedly connected to the transport assembly, the hollow guide plate has an exhaust channel, a gas tank is fixedly connected to the frame, an extrusion cylinder is fixedly connected to the hollow guide plate, a connecting pipe is fixedly connected and communicates between the extrusion cylinder and the gas tank, a pipe is fixedly connected and communicates between the extrusion cylinder and the exhaust channel of the hollow guide plate, a rotating frame is rotatably connected to the hollow guide plate, an electric slide rail is fixedly connected to the hollow guide plate, a movable frame is fixedly connected to the electric slide rail via a slider, the movable frame is movably connected to the rotating frame, and the movable frame is fixedly connected to the piston rod of the extrusion cylinder.

[0007] In a preferred embodiment of the present invention, the pipe and connecting pipe between the extrusion cylinder and the exhaust channel of the hollow guide plate are both fixedly connected and connected to a one-way valve.

[0008] In a preferred embodiment of the present invention, an exhaust mechanism is further included. The exhaust mechanism is disposed on the heat sealing assembly. The exhaust mechanism includes a lead screw, a support frame, a mounting plate, and a pressure rope. Pairs of support frames are fixedly connected to the heat sealing assembly. The support frames are rotatably connected to the lead screw. Pairs of mounting plates are slidably connected to the heat sealing assembly. Axially distributed pressure ropes are fixed between the pairs of mounting plates. The mounting plates are threadedly connected to the lead screw.

[0009] In a preferred embodiment of the invention, the pressure rope is elastic.

[0010] In a preferred embodiment of the present invention, a bonding mechanism is further included. The bonding mechanism is disposed on the frame and includes a rotating belt and a rotating shaft. A pair of rotating shafts are rotatably connected to the frame, and a rotating belt is sleeved between the pair of rotating shafts.

[0011] In a preferred embodiment of the present invention, the rotating belt is provided with uniformly distributed columnar flexible protrusions.

[0012] In a preferred embodiment of the present invention, a clamping mechanism is further included. The clamping mechanism is disposed on the transport component. The clamping mechanism includes a rotating frame and a pressure rod. The pairs of rotating frames are rotatably connected to the transport component through damping rings, and the pressure rod is fixedly connected between the pairs of rotating frames.

[0013] In a preferred embodiment of the present invention, a disinfection mechanism is further included. The disinfection mechanism is disposed on the hollow guide plate and includes a mounting frame and an ultraviolet lamp. The mounting frame is fixedly connected to the hollow guide plate and the ultraviolet lamp is fixedly connected to the mounting frame.

[0014] The beneficial effects of this invention are: 1. Through components such as hollow guide plates and rotating frames, this invention can not only intermittently block the bread, thus enabling the bread to be packaged while maintaining a constant spacing, thereby avoiding the need for manual placement of the bread at equal intervals, but also inject inert gas into the packaging film to prevent some of the bread's components from oxidizing and deteriorating, thereby extending the bread's shelf life and improving the ease of use and practicality of this packaging equipment.

[0015] 2. This invention, through components such as lead screws and pressure ropes, can press down on the packaging film to release air according to user needs during sealing, thereby effectively reducing the total amount of gas inside the packaging film, extending the shelf life of bread, and preventing the packaging film from swelling or even breaking under high temperatures, thus improving the packaging effect of this packaging equipment.

[0016] 3. By rotating components such as the belt and shaft, this invention can press down the raised packaging film before sealing and make the packaging film adhere as closely as possible to the bread. This not only reduces the total amount of gas in the packaging film, thus extending the shelf life of the bread and reducing the swelling of the bag, but also helps the subsequent heat sealing components to seal both ends of the packaging film, improving the practicality of this packaging equipment.

[0017] 4. This invention, through components such as a rotating frame and a pressure bar, can press the overlapping part of the bottom sealing area of ​​the packaging film before sealing the bottom. This not only effectively prevents the packaging film from spreading out during movement, but also helps the subsequent bottom sealing assembly to seal the overlapping part of the bottom of the packaging film, thus improving the practicality of this packaging equipment.

[0018] 5. This invention, through components such as mounting racks and ultraviolet lamps, can sterilize and disinfect bread and packaging films without chemical residues, thereby ensuring packaging hygiene and improving product quality and safety, thus enhancing the practicality of this packaging equipment.

Detailed Implementation

[0032] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0033] Example 1 A packaging device for bread production, such as Figures 1-7As shown, the assembly includes a frame 1, a film winder 11, a protective shell 12, a heat sealing assembly 1201, a bottom sealing assembly 1202, a transport assembly 13, a hollow guide plate 14, an air tank 15, a connecting pipe 16, a rotating frame 17, an electric slide rail 18, a moving frame 19, and an extrusion cylinder 110. The film winder 11 is mounted on the upper left side of the frame 1. The protective shell 12 is fixedly connected to the top right side of the frame 1. The heat sealing assembly 1201 is mounted on the upper right side of the frame 1. The bottom sealing assembly 1202 is mounted on the middle upper side of the frame 1. The transport assembly 13 is mounted on the upper part of the frame 1. A hollow guide plate 14 is fixedly connected to the top left side of the transport assembly 13. 4. An exhaust channel is provided inside the hollow guide plate 14. A gas tank 15 is fixedly connected to the left side of the front side of the frame 1. An extrusion cylinder 110 is fixedly connected inside the hollow guide plate 14. A connecting pipe 16 is fixedly connected and connected between the extrusion cylinder 110 and the gas tank 15. A pipe is fixedly connected and connected between the extrusion cylinder 110 and the exhaust channel of the hollow guide plate 14. A rotating frame 17 is rotatably connected to the lower part of the hollow guide plate 14. An electric slide rail 18 is fixedly connected inside the hollow guide plate 14. A movable frame 19 is fixedly connected to the top of the electric slide rail 18 through a slider. The movable frame 19 is movably connected to the rotating frame 17. The movable frame 19 is fixedly connected to the piston rod of the extrusion cylinder 110.

[0034] like Figure 5 and Figure 6 As shown, the pipe and connecting pipe 16 between the extrusion cylinder 110 and the exhaust channel of the hollow guide plate 14 are both fixedly connected and connected to a one-way valve.

[0035] When workers need to package bread, they can first place multiple loaves of bread sequentially on the left side of the transport component 13, and then activate the film winding machine 11, heat sealing component 1201, bottom sealing component 1202, transport component 13, and electric slide rail 18. The transport component 13 can transport the bread to the right, while the film winding machine 11 can gradually release a long strip of packaging film and wrap it around the bread. The front and rear ends of the packaging film will partially overlap at the bottom of the bread. When the bread and packaging film are transported together by the transport component 13 to the top of the bottom sealing component 1202, the bottom sealing component 1202 will seal the bottom of the bread. The overlapping portion of the packaging film is sealed. As the bread and packaging film continue to be conveyed by the transport component 13 to the bottom of the heat-sealing component 1201, the heat-sealing component 1201 will intermittently move downwards and cut and seal the packaging film, thus completing the packaging of the bread. During this process, the electric slide rail 18 will first drive the moving frame 19 to the right, and the movement of the moving frame 19 to the right will also drive the rotating frame 17 to rotate clockwise and become vertical. At this time, the vertical rotating frame 17 will block the bread. After a preset time interval, the electric slide rail 18 will drive the moving frame 19 to move back and forth once. Moving the moving frame 19 to the left causes the rotating frame 17 to rotate counterclockwise and return to a horizontal position. At this time, the bread can continue to be conveyed to the right under the action of the transport component 13. After passing one piece of bread, the moving frame 19 will move to the right again and cause the rotating frame 17 to rotate to a vertical position to continue to block the subsequent bread. This cycle allows the bread to be packaged while maintaining a constant spacing, avoiding the need for manual placement of the bread at equal intervals. Furthermore, the left and right movement of the moving frame 19 under the action of the electric slide rail 18 also causes the piston rod of the extrusion cylinder 110 to move left and right back and forth. One-way valves are installed in the pipes and connecting pipes 16 between 110 and the exhaust duct of the hollow guide plate 14. Therefore, when the piston rod moves to the left, it will draw the inert gas in the gas tank 15 into the extrusion cylinder 110 through the connecting pipe 16. When the piston rod moves to the right, it will inject the inert gas in the extrusion cylinder 110 into the exhaust duct of the hollow guide plate 14 through the pipe. The inert gas then passes through the exhaust duct and enters the packaging film, thereby reducing the oxygen content in the packaging film and preventing some of the bread's components from oxidizing and deteriorating, thus extending the bread's shelf life. After the bread is packaged, the film roller 11 and the electric slide rail 18 and other components can be closed.

[0036] Example 2 Based on Example 1, such as Figure 2 and Figure 8As shown, it also includes an exhaust mechanism, which is set in the heat sealing assembly 1201. The exhaust mechanism includes a lead screw 2, a support frame 21, a mounting plate 22 and a pressure rope 23. The two support frames 21 are respectively fixed to the front and rear parts of the right side of the heat sealing assembly 1201. The lead screw 2 is rotatably connected to the right part of the support frame 21. The mounting plate 22 is slidably connected to the front and rear parts of the right side of the heat sealing assembly 1201. The pressure rope 23 is axially distributed between the two mounting plates 22. The mounting plate 22 is threadedly connected to the adjacent lead screw 2.

[0037] like Figure 8 As shown, the pressure rope 23 is elastic.

[0038] Before packaging the bread, workers can rotate the screw 2 as needed, thereby moving the mounting plate 22 and the pressure rope 23 upward or downward relative to the heat sealing assembly 1201 to a suitable height. When the heat sealing assembly 1201 moves downward and cuts and seals the packaging film, the mounting plate 22 and the pressure rope 23 also move downward along with the heat sealing assembly 1201. The downward movement of the pressure rope 23 can press down on the packaging film to release air, thereby effectively reducing the total amount of gas in the packaging film, extending the shelf life of the bread and preventing the packaging film from swelling or even breaking under high temperature conditions. The pressure rope 23 needs to be elastic to avoid damaging the bread when pressing down. When the heat sealing assembly 1201 moves upward to reset, the mounting plate 22 and the pressure rope 23 will also move upward to reset together.

[0039] like Figure 2 and Figure 9 As shown, it also includes a bonding mechanism, which is set on the frame 1. The bonding mechanism includes a rotating belt 3 and a rotating shaft 31. The two rotating shafts 31 are rotatably connected to the left and right sides of the upper part of the frame 1, respectively, and the rotating belt 3 is sleeved between the two rotating shafts 31.

[0040] like Figure 2 and Figure 9 As shown, the rotating belt 3 has uniformly distributed columnar flexible protrusions on its exterior.

[0041] When the bread and packaging film move to the right under the action of the transport component 13 and come into contact with the rotating belt 3, the packaging film will drive the rotating belt 3 and the rotating shaft 31 to rotate counterclockwise through friction. The rotating belt 3 will press down on the raised packaging film and make the packaging film as close to the bread as possible. This not only reduces the total amount of gas in the packaging film to extend the shelf life of the bread and reduce the swelling of the bag, but also helps the heat sealing component 1201 to seal both ends of the packaging film. The columnar flexible protrusions evenly distributed on the outside of the rotating belt 3 can increase the friction between it and the packaging film.

[0042] like Figure 10 and Figure 11As shown, it also includes a clamping mechanism, which is disposed on the transport component 13. The clamping mechanism includes a rotating frame 4 and a pressure rod 41. The two rotating frames 4 are rotatably connected to the left and right sides of the upper part of the transport component 13 through damping rings, and the pressure rod 41 is fixed between the two rotating frames 4.

[0043] When the packaging film wraps around the bread and partially overlaps at the bottom, the worker can rotate the rotating frame 4 and the pressure rod 41 downwards to press the overlapping part of the packaging film. This not only effectively prevents the packaging film from coming apart during movement, but also helps the subsequent bottom sealing assembly 1202 to seal the overlapping part at the bottom of the packaging film. When not needed, the rotating frame 4 and the pressure rod 41 can be rotated upwards to reset.

[0044] like Figure 2 and Figure 12 As shown, it also includes a disinfection mechanism, which is set on the hollow guide plate 14. The disinfection mechanism includes a mounting frame 5 and a UV lamp 51. The mounting frame 5 is fixed to the bottom right side of the hollow guide plate 14, and the UV lamp 51 is fixed to the bottom of the mounting frame 5.

[0045] When packaging bread, workers can also turn on the ultraviolet lamp 51. The ultraviolet lamp 51 emits ultraviolet light and sterilizes the bread and packaging film without chemical residue, thereby ensuring packaging hygiene and improving product quality and safety. After the bread is packaged, the ultraviolet lamp 51 can be turned off.

[0046] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
