Description

Technical Field

[0001] The utility model belongs to the technical field of packaging equipment, and particularly relates to a double-rotating-disk type food vacuum packaging machine. Background Art

[0002] Since food has a short shelf life after processing, is easy to deteriorate, and is difficult to store and transport, vacuum packaging is generally used in the market to extend the shelf life of the product, reduce the risk of pathogenic microbial contamination, and reduce the company's storage and transportation costs. Food is generally vacuum packaged using a food vacuum packaging machine, which is generally composed of two separate rotating bodies (filling system and vacuum system). The filling system is intermittently rotating, and the vacuum system is continuous rotating. The packaging workflow is: bag taking → coding → bag opening → air blowing → filling → leveling → vacuuming → sealing → output.

[0003] The existing food vacuum packaging machines lack a device for detecting packaging bags, which leads to missing bags or damaged bags during the packaging process, which can easily cause problems such as loose food packaging, air leakage and deterioration. At the same time, the connection structure between the packaging equipment and the vacuum equipment is relatively complicated, and the processing speeds of the two devices cannot be completely consistent, so the packaging time is long and the efficiency is low.

[0026] Reference Figures 1 to 5 , several embodiments of a double-turntable food vacuum packaging machine of the present invention are given below.

[0027] A double-turntable food vacuum packaging machine comprises a chassis 1, on which are arranged a food packaging device 2, a food vacuum device 3, a feeding device 4 and a control device 5, the food packaging device 2 and the food vacuum device 3 are arranged side by side, and a visual inspection device 6 is arranged at the front end of the food packaging device 2 and the food vacuum device 3, the feeding device 4 is horizontally arranged below the food vacuum device 3, and the control device 5 is electrically connected to the food packaging device 2, the food vacuum device 3, the feeding device 4 and the visual inspection device 6 respectively, so as to control the food packaging device 2 to fill and pack the food, and to perform vacuum processing through the food vacuum device 3, and finally to complete the discharge through the feeding device 4.

[0028] Specifically, components for driving the food packaging device 2 and the food vacuum device 3 are provided in the chassis 1. The visual detection device 6 can detect the packaging filling and vacuum status of the packaging bag in real time to avoid the phenomenon of equipment failure caused by lack of bags. At the same time, the filling system of the food packaging device 2 is intermittent rotation operation, and the vacuum system of the food vacuum device 3 is continuous rotation motion. The advantage of this design is that it can make the equipment intelligent and automated, simple to operate, efficient and stable, and continuous production. In addition, the control device 5 can select different processing and production speeds according to the type of packaged material.

[0029] like Figure 2 As shown, the food packaging device 2 includes a rotatable packaging station turntable 21, a plurality of cylinder grippers 22 connected around the packaging station turntable 21, and a bag feeding mechanism 23, a bag opening mechanism 24, a bag holding mechanism 25 and a filling mechanism 26 arranged on the edge of the packaging turntable and capable of cooperating with the cylinder grippers 22. A packaging bag detection mechanism 27 is arranged between one end of the bag feeding mechanism 23 and the cylinder grippers 22. The bag opening mechanism 24 and the bag holding mechanism 25 are both connected in cooperation with the cylinder grippers 22, and a feeder is externally connected to the filling mechanism 26.

[0030] Specifically, the packaging bag is loaded through the bag feeding mechanism 23, and is clamped by the cylinder gripper 22 after being detected by the packaging bag detection mechanism 27. As the packaging station turntable 21 rotates, the packaging bag is transferred to the bag opening mechanism 24 to complete the bag opening. At the same time, the bag expansion mechanism 25 blows air into the bag to expand the packaging bag and keep it in an open state. As the packaging station turntable 21 rotates, the packaging bag is sent to the filling mechanism 26 for loading, and quantitative packaging is completed under the quantitative feeding of the external feeder. The loaded packaging bag is then sent to the food vacuum device 3. In addition, the packaging bag detection mechanism 27 arranged between the bag feeding mechanism and the packaging station turntable 21 can detect in real time whether there is a bag shortage or the bag is not in place during the bag taking process, so as to control the start and stop of the packaging machine and avoid safety accidents caused by malfunctions.

[0031] In this embodiment, the food vacuum extraction device 3 includes a vacuum station turntable 31, a vacuum extraction mechanism 32 and a vacuum extraction air pump box 33. There is a transfer station between the vacuum station turntable 31 and the packaging station turntable 21. The transfer station is provided with a packaging bag transfer mechanism 34 that can transfer the packaging bag filled with food on the packaging turntable to the vacuum extraction mechanism 32; the packaging bag transfer mechanism 34 includes a swing arm 341 arranged between the packaging station turntable 21 and the vacuum station turntable 31 and a transfer manipulator 342 that can be opened and closed and is arranged on the swing arm 341. One end of the swing arm 341 is movably connected to the transfer manipulator 342, and the other end is fixedly connected to the vacuum extraction mechanism 32.

[0032] Specifically, when the packaging bag after filling on the packaging station turntable 21 runs to the output station, the swing arm 341 in the packaging bag transfer mechanism 34 drives the transfer robot 342 through the motor of the driving component, and the transfer robot 342 is linked with the swing arm 341, causing the swing arm 341 to swing along its supporting end. When the swing arm 341 swings to the packaging station turntable 21, it clamps the packaging bag on the cylinder gripper 22, and then swings to the vacuum mechanism 32 through the linkage of the transfer robot 342, and drives the vacuum mechanism 32 to vacuum the packaging bag through the vacuum air pump box 33, thereby improving work efficiency.

[0033] In this embodiment, a plurality of vacuum pumping mechanisms 32 are provided, and the plurality of vacuum pumping mechanisms 32 are fixedly connected to the edge of the vacuum station turntable 31 and rotate together with the vacuum station turntable 31. The vacuum pump box 33 is installed above the vacuum pumping mechanism 32, and the vacuum pump box 33 is pneumatically connected to the vacuum pumping mechanism 32; the unloading device 4 includes a unloading conveyor belt 41 and a driving mechanism 42, the driving mechanism 42 is arranged at one end of the unloading conveyor belt 41, and is transmission-connected to the unloading conveyor belt 41, and the unloading conveyor belt 41 is arranged directly below the vacuum pumping mechanism 32.

[0034] Specifically, a vacuum selection output mechanism 35 is mounted on the vacuum station turntable 31, which enables the vacuum pump to be connected to a plurality of vacuum pumping mechanisms 32. The setting of the vacuum selection output mechanism 35 allows the vacuum pumping mechanism 32 to rotate with the vacuum station turntable 31, while the vacuum pump box 33 can be stably connected to the vacuum pumping mechanism 32. That is, when the vacuum station turntable 31 rotates, the vacuum pumping mechanism 32 thereon rotates with it. At this time, the corresponding vacuum pumping mechanism 32 vacuums the packaging bag therein, and the replacement of air intake and air outlet is completed through the vacuum selection output mechanism 35, thereby implementing air extraction or exhaust. This arrangement has a compact structure and stable operation. At the same time, after the vacuumization is completed, the packaging bag is heat-sealed and falls onto the unloading conveyor belt 41 below to complete the unloading.

[0035] The working principle of this utility model:

[0036] During operation, the packaging bag is loaded through the bag feeding mechanism 23, and is clamped by the cylinder gripper 22 after being detected by the packaging bag detection mechanism 27. With the rotation of the packaging station turntable 21, the packaging bag is transferred to the bag opening mechanism 24 to complete the bag opening. At the same time, the bag support mechanism 25 blows air into the bag to expand the packaging bag and keep it in an open state. With the rotation of the packaging station turntable 21, the packaging bag is sent to the filling mechanism 26 for loading, and then sent to the transfer station. At this time, the transfer robot 342 grasps the packaging bag and sends the packaging bag to the vacuum mechanism 32 under the action of the swing arm 341. The vacuum mechanism 32 starts the vacuum operation under the power of the vacuum pump box 33. After the vacuum is completed, the packaging bag mouth is sealed by heat sealing to complete the loading, vacuuming and sealing process of a packaging bag; finally, the material is unloaded to the unloading device 4 to complete the unloading, and the above steps are repeated to form a production line; The present invention uses prefabricated packaging bags, which are transported from the bag feeding mechanism 23 by the control device 5, and under the rotation of the packaging station turntable 21, the processes of bag taking, bag supporting, bag filling, transfer, etc. are completed in sequence. The packaging bag transfer mechanism 34 connected between the vacuum pumping mechanism 32 and the packaging station turntable 21 can transport the packaging bags filled on the packaging station turntable 21 to the vacuum pumping mechanism 32 for vacuum pumping, which does not require manual operation, has strong sustainability, and can avoid contamination of the filler; at the same time, the packaging bags are vacuumed and sealed in the enclosed space of the vacuum pumping mechanism 32, so that the vacuum pumping is more thorough; there are multiple vacuum pumping mechanisms 32 and they are installed on the rotatable vacuum station turntable 31, and the vacuum station turntable 31 rotates in the same position as the packaging station turntable 21, so that the packaging bags can be vacuumed and sealed continuously, and the working efficiency is greatly improved.

[0037] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
