Description

TECHNICAL FIELD

[0001] The utility model relates to soy products packaging technical field especially soy products packaging with multi -functional packaging machine. BACKGROUND

[0002] With the continuous improvement of people's living standards, the demand for various convenience foods also increases, which further promotes the rapid development of China's food packaging industry. Soy products, as an important category of convenience foods, are diverse in types and forms, such as soy milk, tofu, fermented bean curd, douchi, soybean paste, and dried tofu. Due to the high protein and fat content of soy products, and the fact that most of them contain lysine needed by the human body, they are rich in nutritional value. However, soy products are easily affected by the external environment during storage and transportation, leading to mold and oxidation, which affects their quality and safety. In order to extend the shelf life of soy products and maintain their nutritional ingredients, it is particularly important to use appropriate packaging methods.

[0003] Traditional soy product packaging methods rely heavily on manual operation or simple mechanical equipment. These methods not only have low efficiency, but also cannot guarantee the consistency and sealing of the packaging. With the development of technology, mechanical equipment with higher automation has gradually replaced manual operation and become the mainstream choice for soy product packaging. Among them, soy product packaging machines have been widely used in the field of soy product packaging due to their high efficiency, precision, and reliability.

[0004] Some existing packaging machines rely on manual operation in the packaging box unloading process. Workers need to manually place the packaging boxes one by one in the designated position of the packaging machine. This process not only consumes a lot of manpower and time, but also due to the instability and subjectivity of human operation, it is easy to cause the packaging box to be placed inaccurately, which affects the subsequent packaging process. In addition, for the unloading process of packaged soy products, traditional equipment lacks effective buffer protection mechanism. When the packaged soy products are unloaded from the conveying belt to the collecting device, due to the influence of the falling height and the weight of the products, a large impact force will be generated. This impact force directly acts on the products, often causing the packaging of soy products to be damaged or deformed, and even the internal soy products to be squeezed and damaged, which seriously affects the appearance integrity and quality stability of the products. Therefore, in view of the above problems, a multifunctional packaging machine for soy product packaging is proposed to solve the above problems. SUMMARY

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a multi-functional packaging machine for bean products, including a protective shell 1, which is a rectangular shell. A chain conveyor belt 2 is provided in the middle of the protective shell 1. The chain conveyor belt 2 consists of a chain and multiple fixed boxes fixed on the chain, and serves as a transport carrier for the packaging boxes, sequentially conveying the packaging boxes placed in its fixed boxes to the next process.

[0034] A hydraulic sealing mechanism 3 is installed at the top of the protective shell 1. The hydraulic sealing mechanism 3 heat-seals the packaging box filled with soy milk products to ensure the airtightness of the product packaging. A packaging film structure is also installed on the outside of the hydraulic sealing mechanism 3. A feeding rack 4 is fixedly connected to the side of the top of the protective shell 1 away from the hydraulic sealing mechanism 3. The feeding rack 4 has a feeding port in the middle and its bottom is fixed to the left side of the top of the protective shell 1. Two support rods 5 are fixedly connected to the top of the feeding rack 4. A placement cylinder 6 is fixedly connected to the adjacent side of the two support rods 5. The support rods 5 support the placement cylinder 6, which is suspended at the top of the feeding rack 4. The placement cylinder 6 is used to place the packaging box containing soy milk products, serving as a temporary storage container for the packaging box.

[0035] refer to Figure 2 , Figure 3 A hydraulic cylinder 7 is fixedly connected to the rear top of the unloading rack 4. The hydraulic cylinder 7 consists of a cylinder barrel, a piston, and a piston rod. A transmission rod 8 is fixedly connected to the drive end of the hydraulic cylinder 7, and the transmission rod 8 serves to transmit force and convert motion. A connecting rod 9 is rotatably connected to the side of the transmission rod 8 away from the hydraulic cylinder 7. The transmission rod 8 transmits the linear reciprocating motion of the hydraulic cylinder 7 to the connecting rod 9. The bottom end of the connecting rod 9 is slidably connected to the top of the unloading rack 4, and the connecting rod 9 slides and extends at the top of the unloading rack 4 under the drive of the transmission rod 8.

[0036] The top end of the blanking frame 4 is rotationally connected with four isolation plates 10, which are flat structures. The middle part of the isolation plate 10 is fixedly connected with a connecting block 11, which is fixed at the middle part of the side edge of the isolation plate 10. The adjacent side of the adjacent isolation plate 10 is rotationally connected with a connecting rod 12, which is designed to connect two isolation plates 10, so that the diagonal isolation plates 10 can rotate synchronously.

[0037] The rear side of the connecting rod 12 is fixedly connected to the front side of the connecting rod 9, and the rear side of the connecting rod 12 is fixedly connected to the front side of the connecting rod 9. The top end of the adjacent connecting block 11 is rotationally connected with a connecting rod 13, which is connected with the connecting rod 12 through the connecting block 11, so that the four isolation plates 10 can be connected together, so that the four isolation plates 10 can rotate synchronously. The top end of the isolation plate 10 is fixedly connected with an isolation plate 14, which is shorter than the isolation plate 10, and the isolation plate 14 is rotationally connected with the isolation plate 10, which can realize the clamping and loosening action of the packaging box.

[0038] Reference Figure 4 , Figure 5 , the protective shell 1 away from the blanking frame 4 side is provided with elastic assembly for protecting the packaged bean products, the elastic assembly includes rotating shaft 15, rotating shaft 15's front and rear two sides outside rotationally connected in the protective shell 1 away from the blanking frame 4 side bottom, rotating shaft 15 as the rotating shaft of blanking plate 16, make blanking plate 16 can rotate around it. The outer side of the rotating shaft 15 away from the protective shell 1 is fixedly connected with the blanking plate 16, and the side of the blanking plate 16 close to the positioning plate 21 is slidingly connected to the outer side of the protective shell 1, when the soy milk products fall from the chain transmission belt 2, the blanking plate 16 will accept the soy milk products. The bottom end of the blanking plate 16 is fixedly connected with the connecting roller 17, and the connecting roller 17 connects the blanking plate 16 and the gas spring 18.

[0039] The bottom end of the connecting roller 17 is fixedly connected with the gas spring 18, and the gas spring 18 utilizes the compression and expansion characteristics of the gas in its interior. When subjected to the impact force transmitted by the connecting roller 17, it undergoes expansion and contraction deformation, and buffers the impact force through its own elastic force. The outer part of the gas spring 18 is provided with a reset spring 19, which cooperates with the gas spring 18. After the gas spring 18 is subjected to impact force expansion and contraction, it helps the gas spring 18 to recover to the initial state by utilizing its own elastic force. At the same time, it also provides elastic force during the entire buffering process, enhances the buffering effect, and ensures that the elastic assembly can continuously and effectively buffer the blanking impact force of the soy milk products, which is one of the auxiliary buffering and resetting components in the elastic assembly.

[0040] The top end of the reset spring 19 is fixedly connected to the bottom end of the connecting roller 17, and the bottom end of the reset spring 19 is fixedly connected to the side of the supporting ring 20 close to the connecting roller 17. The reset spring 19 is consistent with the elastic expansion and contraction direction of the gas spring 18 through the supporting ring 20.

[0041] The outer part of the gas spring 18 is fixedly connected with a supporting ring 20, which fixes the relative position of the gas spring 18 and the return spring 19. The bottom end of the protective shell 1 is fixedly connected with positioning plates 21 on both sides, and the bottom end of the gas spring 18 is rotatably connected to the middle part of the positioning plate 21 near the connecting roller 17. The positioning plate 21 positions and supports the bottom end of the gas spring 18, and limits the movement range of the gas spring 18. The rear middle part of the protective shell 1 is fixedly connected with a storage tank 22, which is used for storing soy milk products. The front middle part of the storage tank 22 is provided with a soy milk discharging mechanism 23, which drives the soy milk in the storage tank 22 to work by a water pump.

[0042] Working principle: before use, first add soy milk products to the storage tank 22, and place the packaging box for holding soy milk products in the placing cylinder 6. Then, connect the external power supply, start the soy milk discharging mechanism 23, the hydraulic cylinder 7, the chain transmission belt 2 and the hydraulic sealing mechanism 3.

[0043] After the hydraulic cylinder 7 is started, the driving end will drive the transmission rod 8 to move, and the transmission rod 8 will in turn drive the connecting rod 9 fixedly connected with the connecting rod 1 12 to move intermittently. With the intermittent expansion and contraction of the connecting rod 9, the isolation plate 1 0 connected and fixed thereto will produce reciprocating deviation with the rear two isolation plates 1 0 as the fulcrum. Since the four corner isolation plates 1 0 at the top of the discharging frame 4 are connected with each other through the connecting block 1 1 and the connecting rod 1 2, when one of the corner isolation plates 1 0 rotates, the other three corner isolation plates 1 0 will also rotate synchronously. In this process, by virtue of the acute angle formed by the isolation plate 1 0 and the isolation plate 2 14, the packaging box is alternately loosened and tightened by continuously rotating around the isolation plate 1 0, so that the packaging box can automatically fall into the fixed box on the chain transmission belt 2, and then the packaging box will move forward with the rotation of the chain transmission belt 2.

[0044] When the chain transmission belt 2 with the packaging box moves to the bottom end position of the soy milk discharging mechanism 23, the started soy milk discharging mechanism 23 will rotate intermittently by means of the external power supply, so as to discharge the packaging box quantitatively until the packaging box is filled with soy milk products. The packaging box filled with soy milk will continue to move with the chain transmission belt 2 to the position where the hydraulic sealing mechanism 3 is located, and the started hydraulic sealing mechanism 3 will heat and seal the packaging box.

[0045] After the sealing is completed, the chain conveying belt 2 continues to operate until the packaging box moves to the right head of the chain conveying belt 2. At this time, the packaged soy milk product will be separated from the fixed box due to the rotation of the chain conveying belt 2 and will fall to the top end of the discharging plate 16. The impact force generated when the soy milk product is discharged will be transmitted to the connecting roller 17 by the discharging plate 16. After being impacted, the connecting roller 17 will squeeze the gas spring 18 and the return spring 19, causing them to stretch and deform. The gas spring 18 and the return spring 19 rely on their own elastic force to buffer the impact force generated when the soy milk product is discharged, thereby avoiding product breakage caused by the impact of the discharge. Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application 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 replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
