Description

An automatic packaging machine Technical Field

[0001] This utility model relates to the field of sauerkraut packaging technology, specifically to an automatic packaging machine. Background Technology

[0002] Automatic packaging machines are mainly used for the automatic packaging of materials in the food, pharmaceutical, and chemical industries, as well as plant seeds. They are also used in the pickling process of sauerkraut to package the pickled sauerkraut in quantitative quantities.

[0003] However, in the existing packaging machines used in the pickled vegetable production process, due to the irregular shape of the pickled vegetables, the pickled vegetables that fall into the packaging bag during quantitative packaging are often packed into round clumps. In the subsequent sealing process, the uneven filling of the pickled vegetables in the packaging bag can easily cause misalignment at the bag opening, resulting in uneven sealing edges and affecting the sealing effect. In view of this, we propose an automatic packaging machine. Summary of the Invention

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example: Referring to Figures 1-5, an automatic packaging machine includes a box body 100 and a discharge frame 110 disposed on the upper side of the box body 100. A cylindrical component 200 is connected to the side wall of the box body 100 via a connecting frame 120. A rotating shaft 220 is rotatably connected to the middle of the cylindrical component 200. A baffle 230 for blocking the lower outlet of the discharge frame 110 is fixedly installed on the rotating shaft 220. Specifically, this application also includes an outer shell for enclosing and protecting the box body 100 and the discharge frame 110. Specifically, it also includes a frame 130 fixedly connected to the top of the box body 100. Two frames 300 are movably connected inside the frame 130. The frame 300 is provided with a guide groove 301, and a squeezing roller 320 is provided inside the guide groove 301. A retaining ring 310 for securing the packaging bag is provided on the upper side of the frame 300. Specifically, in this application, through the frame 300 and the retaining ring 310 fixedly installed on its upper side, the retaining ring 310 can open and keep the opening of the packaging bag fixed. Correspondingly, when the baffle 230 fixedly installed on the rotating shaft 220 rotates a certain angle, the pickled vegetables at the lower outlet of the unloading frame 110 will fall into the packaging bag, thereby achieving packaging.

[0033] In this application, to address the issue of pickled vegetables falling from the unloading frame 110 into the packaging bag accumulating in the same position and affecting subsequent sealing, a movable plate 400 is movably connected inside the housing 100. A connecting shaft 410 is fixedly connected to the movable plate 400. The upper end of the connecting shaft 410 extends through the housing 100 to the outer wall and is fixedly connected to a movable block 420. The movable block 420 is provided with a groove 421 for limiting the movement trajectory of the overlapping shaft 321 at the end of the extrusion roller 320. When gas is injected into the housing 100, the groove 421 corresponding to the movable plate 400 is movably connected to the housing 100. The movable plate 400 inside the 00 will move upward, thereby driving the movable block 420 to move upward synchronously. At this time, the squeezing roller 320 connected to the frame 300 will move upward. During this process, in conjunction with the sliding fit between the end overlapping shaft 321 of the squeezing roller 320 and the guide groove 301, the squeezing roller 320 moves upward to achieve contact between the squeezing roller 320 and the outer wall of the packaging bag, and flatten the pickled vegetables piled up inside the packaging bag, so that the pickled vegetables are evenly placed inside the packaging bag to facilitate the subsequent sealing operation.

[0034] Specifically, the guide groove 301 includes a bent portion located at the lower side and a vertical portion located at the upper side. The bent portion and the vertical portion are horizontally connected. The outer wall of the overlapping shaft 321 is slidably engaged with the inner wall of the guide groove 301. When the overlapping shaft 321 slides within the vertical portion of the guide groove 301, the outer wall of the extrusion roller 320 will exceed the outer wall of the frame 300 and extrude pressure on the outer wall of the packaging bag. The slide groove 421 is a horizontal straight groove. When the moving block 420 moves upward, the overlapping shaft 321 will slide within the slide groove 421. In this application... It needs to be explained how the extrusion roller 320 extrudes the outer wall of the packaging bag. Specifically, in this application, the guide groove 301 on the inner wall of the frame 300 consists of a bent part and a vertical part. When the moving block 420 moves upward, the corresponding overlapping shaft 321 also moves upward synchronously, and the overlapping shaft 321 slides on the inner wall of the slide groove 421. During this process, the two extrusion rollers 320 located on different frames 300 will approach each other and extrude the packaging bag to distribute the pickled vegetables piled up in the packaging bag evenly.

[0035] In one implementation, to ensure the efficiency of packaging, in this application, a rotating plate 221 is fixedly installed on the outer wall of the cylindrical component 200 on the rotating shaft 220; it also includes a cavity 201 opened inside the cylindrical component 200, and a connecting pipe 210 is connected to the lower side of the cavity 201. The connecting pipe 210 is in communication with the inside of the box 100. The outer wall of the rotating plate 221 is slidably engaged with the inner wall of the cavity 201. When the rotating shaft 220 rotates and drives the baffle 230 to block the lower outlet of the unloading frame 110, the gas in the cavity 201 will enter the inside of the box 100 and drive the moving plate 400 to move upward. Once the pickled vegetables in the packaging bag are packaged in a measured quantity, the corresponding rotating shaft 220 will rotate. On one hand, the baffle 230, which is fixedly connected to the rotating shaft 220, will gradually block the lower outlet of the unloading frame 110. In this process, the rotating plate 221, which is fixedly connected to the rotating shaft 220, will rotate in the cavity 201 and compress the gas in the cavity 201, thereby allowing the gas inside the cavity 201 to enter the box 100 and drive the movable plate 400, which is movably connected in the box 100, to move upward. This allows the squeezing roller 320 to complete the squeezing of the packaging bag. In other words, once the pickled vegetables are placed in the packaging bag, the squeezing roller 320 will quickly flatten the pickled vegetables in the packaging bag, ensuring the efficiency of the packaging.

[0036] Preferably, in this application, a guide shaft 131 is provided in the middle of the frame 130, and the two frames 300 are slidably connected to the guide shaft 131; and a receiving plate 140 is provided in the middle of the top surface of the frame 130, which is used to receive the packaging bag. The retaining ring 310 is curved, and the magnetic block on the lower inner wall of the retaining ring 310 magnetically attracts the magnetic sheet provided on the outer wall of the frame 300 to clamp the opening of the packaging bag. During the clamping process, the distance between the two frames 300 is relatively close, which facilitates the installation of the packaging bag. After the installation is completed, the two frames 300 will move away from each other along the guide shaft 131 to open the bag opening, which facilitates the bagging of pickled vegetables.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
