Description

Technical Field

[0001] The utility model relates to the field of food packaging machinery, in particular to a packaging device for a multi-functional bread production line. Background Art

[0002] In the process of making bread, flour added with different ingredients and various additives is kneaded through stirring, and then formed manually or by a bread automatic forming machine, or filled, cut, fermented, baked, cooled and sterilized, and then subjected to individual automated packaging, boxing or bagging and other processes to complete. In the automatic packaging process of individual bread, it is divided into manual feeding automatic packaging method and automatic handling packaging method. For the above automatic handling packaging method, the bread is poured into a vibrator or a conveyor belt manually or mechanically, and then passes through a multi-stage differential conveyor belt with a guide plate to arrange the bread in a column direction, forming corresponding columns according to the number of packaging machines in the subsequent process. During this process, due to the combined action of the speed difference and different resistances of the baffles, the bread with the arc surface facing down will automatically turn to the top, and in this way, the messy and irregular bread is sorted into a regular formation arranged in columns.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1 to 3 , an embodiment provided by the present utility model: A packaging device for a multifunctional bread production line includes a main control box 1. The main control box 1 serves as the core control center of the entire device, integrating a power switch, an operation interface, and various control buttons. Through the main control box 1, an operator can conveniently start or stop the device and adjust various parameters such as the transmission speed and heating temperature. A protective plate 2 is fixedly connected to the rear side of the main control box 1. The protective plate 2 is installed on the rear side of the main control box 1, and its main function is to protect the internal electrical components from the influence of the external environment, such as dust, moisture, etc.

[0032] The left end of the front side of the protective plate 2 is fixedly connected to a first conveyor belt 3. The first conveyor belt 3 is the main transmission mechanism in the device and is used to convey the bread to be packaged from one end to the other end. Its surface is usually made of food-grade materials to ensure food safety. The left end of the first conveyor belt 3 is fixedly connected to a bracket 4. The bracket 4 supports the right side of the first conveyor belt 3 to keep the first conveyor belt 3 in a horizontal state. The left and right sides of the top of the first conveyor belt 3 are fixedly connected to support rods 5, and a support plate 6 is fixedly connected to the middle of the two support rods 5. The support rods 5 are fixed at the two right ends of the first conveyor belt 3 and are used to support and fix the support plate 6.

[0033] Refer to Figure 1 , Figure 2, on the left side of the top end of the support plate 6, a first telescopic cylinder 7 is fixedly connected. The driving end of the first telescopic cylinder 7 is fixedly connected with a slider 8. The bottom end of the slider 8 is slidably connected to the inner wall of the top end of the support plate 6. The slider 8 is connected to the driving end of the first telescopic cylinder 7 and can slide within the inner wall of the top end of the support plate 6. On the front and rear sides of the top end of the slider 8, a pull rod 9 is rotatably connected. One end of the pull rod 9 away from the slider 8 is rotatably connected to a connecting plate 10. The top end of the connecting plate 10 is fixedly connected with a baffle 11. The movement of the slider 8 drives the pull rod 9, the connecting plate 10, and the baffle 11 to move centrally, thereby realizing the central movement of the bread.

[0034] The bottom end of the baffle 11 is slidably connected to the top end of the first conveyor belt 3. The left end of the baffle 11 is rotatably connected to a rotating plate 12. The left end of the rotating plate 12 is rotatably connected to the left ends of the front and rear sides of the first conveyor belt 3. The baffle 11 is connected to the top end of the connecting plate 10 and slides on the surface of the first conveyor belt 3. The function of the baffle 11 is to guide the moving direction of the bread to ensure that the bread can accurately enter the next process, and the right sides of two of the baffles 11 are of different lengths.

[0035] In the middle of the front and rear sides of the support plate 6, two guide rods 13 are fixedly connected. The left and right sides of the top ends of the two connecting plates 10 are slidably connected to the outside of the two guide rods 13. The guide rods 13 guide the linear central movement of the connecting plates 10. On the right side of the top end of the main control box 1, a support cover 14 is fixedly connected. The support cover 14 is fixedly connected to the right side of the top end of the main control box 1 to provide support and protection for the cutting assembly. A through groove 15 is opened at the top end of the support cover 14. A cutting assembly is fixedly connected to the top end of the support cover 14. The through groove 15 is opened at the top end of the support cover 14 to provide a rotating space for the first rotating shaft 17 and the second rotating shaft 18 in the cutting assembly. The design of the through groove 15 takes into account dimensional accuracy and wear resistance to ensure that the rotating shaft can rotate smoothly without obstruction during the rotation process.

[0036] Reference Figure 1 , in the middle of the top end of the main control box 1, a second conveyor belt 31 is arranged. In the middle of the front side of the protective plate 2, a control console 27 is arranged. On the left side of the top end of the second conveyor belt 31, a bag pressing frame 28 is arranged. At the left end of the front side of the protective plate 2, a top shaft 29 is fixedly connected. At the left end of the front side of the protective plate 2, a bottom shaft 30 is fixedly connected.

[0037] Reference Figure 4 , the cutting assembly includes a second telescopic cylinder 16. The outer top end of the second telescopic cylinder 16 is fixedly connected to the front side of the top end of the through groove 15. The driving end of the second telescopic cylinder 16 is rotatably connected to a first rotating shaft 17. The middle of the first rotating shaft 17 is rotatably connected to the middle of the inner wall of the through groove 15. The second telescopic cylinder 16 is the driving element in the cutting assembly. It is limited to rotate in the through groove 15 through the first rotating shaft 17, thereby realizing the telescopic movement to drive the stable rotation of the first rotating shaft 17.

[0038] A second rotating shaft 18 is rotatably connected to the inner rear side of the through groove 15. The left and right sides of the bottom ends of the first rotating shaft 17 and the second rotating shaft 18 are rotatably connected to a third rotating shaft 19 respectively. The top ends of the two third rotating shafts 19 are rotatably connected to a connecting shaft 20. The second rotating shaft 18 is indirectly connected to the first rotating shaft 17 through the connecting shaft 20 and can rotate within the through groove 15. When the first rotating shaft 17 rotates, the second rotating shaft 18 will follow. The top end of the connecting shaft 20 is in contact with the inner top end of the support cover 14, which is to limit the up and down distance of the first rotating shaft 17 and the second rotating shaft 18 after rotation. The bottom ends of the front and rear third rotating shafts 19 are rotatably connected to a straight plate 21. The adjacent sides of the two third rotating shafts 19 are slidably connected to the left and right sides of the straight plate 21. The bottom end of the straight plate 21 is fixedly connected to a fixing plate 22. The straight plate 21 is fixedly connected to the bottom end of the fixing plate 22 and provides a sliding track for the third rotating shaft 19.

[0039] The bottom end of the fixing plate 22 is fixedly connected to a heating cutter 23. The fixing plate 22 is fixedly connected to the bottom end of the straight plate 21 and provides an installation platform for the heating cutter 23. Driven by the second rotating shaft 18, the fixing plate 22 can move up and down, thereby driving the heating cutter 23 to cut the bread packaging paper. The front and rear sides on the left side of the fixing plate 22 are fixedly connected with telescopic rods 24 respectively. A spring 25 is sleeved outside the telescopic rods 24. One end of the spring 25 is fixedly connected to the bottom end on the right side of the fixing plate 22, and the other end of the spring 25 is fixedly connected to the front and rear sides of the top end of a pressing plate 26. The bottom ends of the two telescopic rods 24 are fixedly connected to the pressing plate 26. The distance of the pressing plate 26 is lengthened by the telescopic rods 24. Therefore, in the initial state, the pressing plate 26 is lower than the heating cutter 23, that is, the pressing plate 26 will assist the heating cutter 23 to press against and squeeze the packaging paper of the bread, and then through the retraction of the spring 25 and the pressing plate 26, the heating cutter 23 will contact the packaging paper again for heating and cutting.

[0040] Working principle: When in use, first install the packaging plastic bag reel for packaging bread through the top shaft 29, the bottom shaft 30 and the bag pressing frame 28, and then turn on the power through the control console 27 and the main control box 1 to make the first conveyor belt 3 and the guide rod 13 start to convey. At this time, the bread can be placed on the top end of the first conveyor belt 3, and then control the first telescopic cylinder 7 to start, so that the first telescopic cylinder 7 pulls the slider 8 to retract and slide on the support plate 6. As the slider 8 retracts, the slider 8 can pull the connecting plate 10 to slide and gradually concentrate on the guide rod 13 through the pull rod 9. At the same time, the baffle 11 connected to the connecting plate 10 will also gradually concentrate, and the rotating plate 12 will be misaligned and inclined until the size that a bread can move through. At this time, when moving the bread, it will first contact the front rotating plate 12 to disperse the distance and gradually move towards the middle, and then contact the rear rotating plate 12 and then disperse and gradually move to the middle position between the two baffles 11, realizing the centering movement one by one.

[0041] When the bread moves to the left edge position of the guide rod 13, the bread will move onto the second conveyor belt 31 one by one, and is covered by the pre-installed packaging plastic bags from above and below. Then, it will be moved by the moving second conveyor belt 31 to the position of the support cover 14. At this time, the second telescopic cylinder 16 will be activated to drive the first rotating shaft 17 to rotate. While the first rotating shaft 17 rotates, since the coupling shaft 20 is connected to the second rotating shaft 18, the second rotating shaft 18 will rotate simultaneously with the first rotating shaft 17. Thus, the first rotating shaft 17 and the second rotating shaft 18 synchronously push the fixed plate 22 downward through the coupling shaft 20 and the third rotating shaft 19. The downward movement of the fixed plate 22 drives the heating cutter 23 and the telescopic rod 24 to descend. Since the distance of the pressing plate 26 is lengthened through the telescopic rod 24, the pressing plate 26 is lower than the heating cutter 23 in the initial state, that is, the pressing plate 26 will assist the heating cutter 23 to press against the wrapping paper of the bread. Then, through the retraction of the spring 25 and the pressing plate 26, the heating cutter 23 will contact the wrapping paper again for heating and cutting, so as to be able to apply pressure and heat evenly, make the cutting edge neater and smoother, and improve the overall aesthetics of the product.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
