Detailed Implementation
[0025] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0026] like Figures 1-6 As shown, an adjustable bag vacuum packaging machine includes a base 1, a mounting frame 2 fixedly mounted on the top of the base 1, and a conveyor belt 3 installed inside the mounting frame 2.
[0027] The top of the mounting bracket 2 is provided with a sealing mechanism 4 and a guiding mechanism 5. The inside of the mounting bracket 2 is provided with grooves 6 on both sides, and a cleaning component is provided between the two grooves 6.
[0028] In this embodiment, the mounting frame 2 is equipped with a drive device to drive the conveyor belt 3. The packaging bag that needs to be sealed is placed on top of the conveyor belt 3. The rotation of the conveyor belt 3 moves the packaging bag. The guide mechanism 5 can move the two sides of the bag opening towards the middle, so that the packaging bag fits relatively, which facilitates the subsequent air extraction and heat sealing process. When the packaging bag moves to the bottom of the sealing mechanism 4, the sealing mechanism 4 effectively extracts the air from the packaging bag and then heat seals the bag opening. After long-term use, dust easily accumulates on the surface of the conveyor belt 3, or food from inside the packaging bag falls onto the surface of the conveyor belt 3. The cleaning component can effectively clean the dust and food residue and collect them into the collection box 9, improving practicality.
[0029] The guiding mechanism 5 includes a second fixed frame 51, which is fixedly mounted on the top of the mounting frame 2. Two gears 52 are rotatably mounted on the top of the second fixed frame 51, and the two gears 52 mesh with each other. One end of one gear 52 is connected to a first motor 53, and the first motor 53 is fixedly mounted to the second fixed frame 51. An adjustment assembly is provided at the bottom of the second fixed frame 51. The adjustment assembly includes two mounting plates 54, which are symmetrically fixedly mounted on the bottom of the second fixed frame 51. A pulley 55 is rotatably mounted on the bottom of each of the two mounting plates 54, and a transmission belt 56 is provided between each pair of pulleys 55. The bottom ends of the two gears 52 are connected to... The second fixed frame 51 is connected to a drive shaft 57. The bottom ends of both drive shafts 57 pass through the mounting plate 54 and are connected to pulleys 55. The packaging bag containing food is placed upright above the conveyor belt 3. The conveyor belt 3 moves the packaging bag. Since there is an angle between the two mounting plates 54, the opening of the packaging bag moves between the two drive belts 56. The first motor 53 drives the gear 52 to rotate. The two gears 52 drive the pulley 55 to rotate through the drive shaft 57, which in turn makes the drive belt 56 rotate, effectively moving the two sides of the opening of the packaging bag towards the middle. The surface of the drive belt 56 is provided with anti-slip texture to increase the friction with the packaging bag and facilitate subsequent vacuum packaging.
[0030] The sealing mechanism 4 includes a first fixing frame 41, which is fixedly installed on the top of the mounting frame 2. A first hydraulic cylinder 42 and an air extraction assembly are fixedly installed on the top of the first fixing frame 41. The output end of the first hydraulic cylinder 42 passes through the first fixing frame 41 and is fixedly installed on a lifting frame 43. A second hydraulic cylinder 44 is fixedly installed on both sides of the inside of the lifting frame 43. A movable plate 45 is fixedly installed on the output end of each of the two second hydraulic cylinders 44. A heat sealing plate 46 is installed on the opposite side of each of the two movable plates 45. Both movable plates 45 have slidingly mounted limiting rods 410 extending through their exteriors. A clamping plate 411 is fixedly mounted at one end of each limiting rod 410. A groove 412 is provided on one side of the clamping plate 411. A spring 413 is fitted around the limiting rod 410, located between the clamping plate 411 and the movable plate 45. The air extraction assembly includes an air pump 47 and an air extraction pipe 48. The air pump 47 is fixedly mounted on the top of the first fixed frame 41, and the air extraction pipe 48 is fixedly mounted on the bottom of the lifting frame 43. A space is provided between the air pump 47 and the air extraction pipe 48. With a connecting pipe 49, the packaging bag, after its opening is brought close, moves to below the first fixing frame 41. At this time, the second hydraulic cylinder 44 operates, driving the moving plate 45 to move. The two clamping plates 411 move closer together, clamping the opening of the packaging bag. The suction pipe 48 is located inside the bag opening. Through the operation of the air pump 47 and its cooperation with the connecting pipe 49, the suction pipe 48 extracts air from inside the packaging bag. Because the two clamping plates 411 have grooves 412 that fit the suction pipe 48, the air can be completely sucked out. The bottom is higher than the top of the heat-sealing plate 46. After all the air in the packaging bag is extracted, the second hydraulic cylinder 44 continues to drive the moving plate 45 to move, and the spring 413 is compressed until the two heat-sealing plates 46 are in contact with the packaging bag. The heat-sealing plates 46 work to heat-seal the packaging bag. The first hydraulic cylinder 42 can drive the lifting frame 43 to move up and down, which is convenient to adjust according to the amount of food inside the packaging bag. When there is less food, the lifting frame 43 moves down more to reduce the amount of air extracted and reduce the energy consumption of the air pump 47.
[0031] The cleaning component includes a brush 7, which is slidably mounted inside the mounting bracket 2 via two grooves 6. The brush 7 is located below the conveyor belt 3, and the outside of the conveyor belt 3 is in contact with the outside of the brush 7. Both sides of the brush 7 are threaded with knobs 8. A collection box 9 is placed on the top of the base 1 and below the brush 7. Loosening the knobs 8 allows the brush 7 to slide inside the grooves 6. Adjusting the brush 7 to contact the grooves 6 and then locking the knobs 8, the brush 7 sweeps the dust and fallen food on the surface into the collection box 9 for collection during the rotation of the conveyor belt 3, improving practicality.
[0032] Working principle: The food-filled packaging bag is placed upright above the conveyor belt 3. The conveyor belt 3 moves the packaging bag. Due to the angle between the two mounting plates 54, the opening of the packaging bag moves between the two transmission belts 56. The first motor 53 drives the gear 52 to rotate, and the two gears 52 drive the pulley 55 to rotate through the transmission shaft 57, which in turn causes the transmission belt 56 to rotate. This effectively moves the two sides of the packaging bag opening towards the middle, facilitating subsequent vacuum packaging. During the movement of the packaging bag, the distance between the two moving plates 45 is relatively close, so that the guide bag opening is located between the two moving plates 45. When the packaging bag moves to directly below the first fixed frame 41, the second hydraulic cylinder 44 drives the moving plates 45 to move. The two clamping plates 411 move closer together to clamp the opening of the packaging bag. At this time, vacuuming begins. The air tube 48 is located in the bag opening. Through the operation of the air pump 47 and the cooperation of the connecting pipe 49, the air extraction tube 48 extracts the air from inside the packaging bag. Since the two clamping plates 411 have grooves 412 that are adapted to the air extraction tube 48, the air can be completely sucked out. The bottom of the air extraction tube 48 is higher than the top of the heat sealing plate 46. After all the air in the packaging bag is extracted, the second hydraulic cylinder 44 continues to drive the moving plate 45 to move, and the spring 413 is compressed until the two heat sealing plates 46 are in contact with the packaging bag. The heat sealing plate 46 heat seals the packaging bag. The operation of the first hydraulic cylinder 42 can drive the lifting frame 43 to move up and down, which can be adjusted according to the amount of food inside the packaging bag. When there is less food, the lifting frame 43 moves down more to reduce the amount of air extracted and reduce the energy consumption of the air pump 47.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
