[0002] Automatic packaging machines are generally divided into semi-automatic packaging machines and fully automatic packaging machines. Automatic packaging machines are mainly used for automatic packaging of materials in the food, medicine, chemical and other industries and plant seeds. The materials can be in the form of granules, tablets, liquids, powders, pastes, etc. Automatic packaging machines have the functions of automatically completing metering, filling, bag making, sealing, cutting, conveying, printing production batch numbers, adding easy-to-cut edges, no-material warning, stirring, etc.

[0003] Automatic packaging machines for powder materials generally have two types: internal extraction and external extraction. Internal extraction means putting the packaging bag into a confined space, and then vacuuming the confined space. After reaching the preset vacuum degree, the bag mouth is heat-sealed by the sealing device. However, internal extraction vacuum packaging machines are generally horizontal, that is, the confined space is opened and closed by moving the box left and right. However, this method occupies a large space and is expensive. For small-batch production packaging workshops, the investment and cost ratio do not match, and are often limited by installation space.

DETAILED DESCRIPTION

[0032] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0033] The utility model discloses a cabinet-type sliding door inner-drawing ton bag vacuum packaging machine with a self-locking function.

[0034] Reference Figures 1 to 10 A cabinet-type sliding door internal vacuum packaging machine for ton bags with a self-locking function comprises a main frame 1, a vacuum zone 11 is arranged in the main frame 1, a vacuum tube is connected to the vacuum zone 11, and a sealing device 12 is arranged in the vacuum zone 11. A sliding door frame 2 is fixedly connected to the main frame 1, a moving door 3 is slid in the sliding door frame 2, and the moving door 3 has an open state and a closed state. When the moving door 3 is in the open state, the moving door 3 is located on one side of the main frame 1 so that one side of the vacuum zone is open; when the moving door 3 is in the closed state, the moving door 3 fits with the main frame 1 and closes the vacuum zone 11.

[0035] During operation, the packaging bag containing the material is transported into the vacuum zone 11, and then the movable door 3 is driven to make the movable door 3 enter a closed state. At this time, the vacuum tube starts to evacuate the bag. After the vacuum degree requirement is reached, the sealing device 12 performs sealing. After the sealing is completed, the bag mouth is cooled, and the air is exhausted and the pressure is released at the same time, and the movable door 3 enters an open state, and the packaging bag is transported out of the vacuum zone 11 to complete the vacuum packaging.

[0036] Specifically, a sliding door hook 4 is provided between the sliding door frame 2 and the sliding door 3, and a plurality of sliding door hooks 4 are provided along the length direction of the sliding door frame 2. The sliding door hook 4 includes a slider, a sliding bearing 41 and a sliding rod 42, wherein the sliding bearing 41 is fixedly connected to the slider, and the slider slides on a slide rail 43 of the sliding door frame 2 along the length direction of the sliding door frame 2. The sliding rod 42 is fixedly connected to the top of the sliding door 3, and the sliding rod 42 is arranged along the thickness direction of the sliding door 3. The sliding bearing 41 is sleeved on the sliding rod 42, and the sliding bearing 41 can slide relative to the sliding rod 42. By using the cooperation between the sliding bearing 41 and the sliding rod 42, the sliding door 3 can move relative to the sliding door frame 2 along its thickness direction, thereby reducing the influence of the sliding door 3 on the sliding door frame 2 when it is subjected to force.

[0037] The sliding door frame 2 is provided with a limiting assembly 5, and a plurality of limiting assemblies 5 are provided along the length direction of the sliding door frame 2. The limiting assembly 5 includes a limiting frame 51 and limiting wheels 52, and two limiting wheels 52 are provided. The two limiting wheels 52 are provided on both sides of the sliding door 3 along the thickness direction of the sliding door 3, so as to limit the sliding door 3 and reduce the possibility of the sliding door 3 being separated from the sliding door frame 2.

[0038] Furthermore, hydraulic buffers 53 are installed on both inner side walls of the sliding door frame 2 along its length direction, and the hydraulic buffers 53 are suitable for contacting with the sliding door 3 to achieve buffering. A sensor switch is also installed on the sliding door frame 2. When the sliding door 3 moves to the front of the main frame 1 and covers the vacuum zone 11, the sensor switch is triggered, indicating that the sliding door 3 moves into place.

[0039] Specifically, the main frame 1 is provided with a locking assembly 6, and the locking assembly 6 is provided with two groups along the length direction of the mobile frame. The locking assembly 6 includes a linear drive member 61, a locking block 62 and a locking seat 63. The linear drive member 61 is fixedly connected to the main frame 1, the movable end of the linear drive member 61 is fixedly connected to the locking block 62, the locking seat 63 is fixedly connected to the mobile door 3, and a locking groove 631 is provided on the locking seat 63. When the mobile door 3 is in a closed state, the locking seat 63 is located between the main frame 1 and the locking block 62, and the movable end of the linear drive member 61 is located in the locking groove 631. The linear drive member 61 is electrically connected to the induction switch. When the induction switch is triggered, an electrical signal is sent to the linear drive member 61, and the linear drive member 61 is started, and the locking seat 63 is pulled toward the main frame 1 through the locking block 62, thereby locking the mobile door 3. The linear drive member 61 can be a cylinder or an electric cylinder. The two sets of locking components 6 are staggered along the front-to-back direction of the main frame to avoid interference.

[0040] Specifically, the upper and lower ends of the main frame 1 are provided with a sliding door ejection mechanism 7, which includes a first telescopic driving member 71, an ejection frame 72 and a guide wheel 73. The first telescopic driving member 71 is fixedly connected to the main frame 1, and the ejection frame 72 is fixedly connected to the output end of the first telescopic driving member 71. A plurality of guide wheels 73 are provided, and all are rotatably connected to the ejection frame 72. The guide wheel 73 is used to contact the side of the moving door 3 facing the main frame 1. When the vacuum zone 11 is exhausted and depressurized, the first telescopic driving member 71 is started, pushing the ejection frame 72 to move toward the moving door 3. At this time, the guide wheel 73 abuts against the moving door 3 and pushes the moving door 3 to move, so that the moving door 3 is separated from the main frame 1.

[0041] The main frame 1 is arranged in the installation groove 13 arranged on the ground. The main frame 1 is provided with a rotating plate assembly 15. The rotating plate assembly 15 includes a second telescopic driving member 151 and a flap 152. The second telescopic driving member 151 is fixedly connected to the main frame 1. The flap 152 is rotatably connected to the main frame 1. The movable end of the second telescopic driving member 151 is hinged to the flap 152. The flap 152 has a passing state and an interrupting state. The second telescopic driving member 151 can drive the flap 152 to switch between the passing state and the interrupting state. When the flap 152 is in the passing state, the flap 152 flips to be flush with the bottom surface of the vacuum zone 11, so that the staff can send the packaging bag into or take out the vacuum zone 11 through the ground bull hydraulic vehicle; when the flap 152 is in the interrupting state, the flap 152 flips to a vertical state, so that the movable door 3 can enter the closed state.

[0042] In addition, two limiting columns 14 are installed on the front side of the sliding door frame 2. The distance between the two limiting columns 14 is equal to the width of the vacuum zone 11, which is used to limit the entry of a hydraulic truck with a larger width.

[0043] It should be noted that a sealing strip 31 is fixedly connected to the side of the movable door 3 facing the main frame 1, and a sealing ring groove 32 is provided in the middle of the sealing strip 31. The main frame 1 is composed of a reinforcing plate, and the reinforcing plate is bent into a tile shape by a carbon steel plate to increase the strength. An exhaust pressure relief valve 16 is also installed on the main frame 1 for exhaust pressure relief. Both the first telescopic driving member 71 and the second telescopic driving member 151 can be cylinders.

[0044] The vacuum pipe is connected to a vacuum filter assembly, which includes a vacuum extraction filter frame 9, a vacuum pump 91, a filter cup 92 and a protective cover 93. The filter cup 92 and the protective cover 93 are both installed on the vacuum extraction filter frame 9, the vacuum pump 91 is installed in the protective cover 93, the filter cup 92 is connected to the box body 1, and the vacuum pump 91 is connected to the filter cup 92, so as to facilitate filtering the air extracted from the main frame 1 and reduce material waste.

[0045] Working principle: Through the arrangement of the main frame 1, the sliding door frame 2 and the moving door 3, the vacuum zone 11 can be closed and opened only by driving the moving door 3. Compared with the traditional horizontal internal vacuum packaging machine, this solution has lower processing difficulty and control difficulty, and the volume design is more flexible, the auxiliary conditions required are simple, the requirements for installation space and location are small, and the versatility is higher. At the same time, the overall solution is simple and the cost is lower.

[0046] By setting the locking assembly 6 and the sliding door ejection mechanism 7, the locking assembly 6 also achieves the sealing of the sliding door 3 and the main frame 1 when locking the sliding door 3, and the sliding door ejection mechanism 7 separates the sliding door 3 from the main frame 1, and the two cooperate to achieve the closing and opening of the vacuum zone 11, which is much easier to implement than the traditional horizontal internal vacuum packaging machine that requires the box to move. By setting the sliding door hook 4 and the sliding door frame 2, the sliding door hook 4 is used to enable the sliding door 3 to move relative to the sliding door frame 2 along its own thickness direction, thereby reducing the impact of the sliding door 3 on the sliding door frame 2 when the sliding door 3 is subjected to force.

[0047] Working process: During operation, the staff transports the packaging bag containing the material into the vacuum zone 11 by the hydraulic vehicle, and then the second telescopic driving member 151 drives the flap 152 to flip to a vertical state. At this time, the staff pulls the moving door 3 until the moving door 3 contacts the hydraulic buffer 53 located on one side of the main frame 1 and triggers the induction switch. When the induction switch is triggered, an electrical signal is sent to the linear driving member 61, and the linear driving member 61 starts, and pulls the locking seat 63 toward the main frame 1 through the locking block 62, thereby locking the moving door 3, so that the moving door 3 enters a closed state.

[0048] Then the vacuum tube starts to draw vacuum, and after the vacuum requirement is reached, the sealing device 12 performs sealing. After the sealing is completed, wait for the bag mouth to cool down, and at the same time, the exhaust pressure relief valve 16 performs exhaust pressure relief. When the pressure reaches the normal air pressure, the first telescopic drive member 71 starts to push the ejection frame 72 to move toward the moving door 3. At this time, the guide wheel 73 resists the moving door 3 and pushes the moving door 3 to move, so that the moving door 3 is separated from the main frame 1. Then the staff pulls the moving door 3 to make the moving door 3 enter the open state. At this time, the second telescopic drive member 151 drives the flap 152 to flip to the pass state, and then the staff transports the packaging bag out of the vacuum area 11 through the hydraulic truck to complete the vacuum packaging.

[0049] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
