Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag sealing machines, and particularly relates to a food packaging bag sealing machine. Background Technique

[0002] Food packaging bags are a type of packaging design. In life, in order to facilitate the preservation and storage of food, product packaging bags have emerged. A sealing machine is a machine that seals containers filled with packaging materials. After the product is loaded into the packaging container, in order to seal and preserve the product, maintain the product quality, and avoid product loss, it is necessary to seal the packaging container, and this operation is completed on the sealing machine. Food packaging bags must use a sealing machine.

[0003] When a food packaging bag sealing machine is in use, heat sealing is usually used to seal the packaging bag. However, during the process of sealing the packaging bag by the packaging bag sealing machine, wrinkles often occur at the sealing part of the packaging bag, resulting in an uneven seal of the food packaging bag. Moreover, when the materials in the packaging bag are large, heavy, and the quantity is relatively large, the operator needs to hold the materials by hand for a long time to perform the sealing operation, which is too tiring after a long time of operation. Content of the Utility Model

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A food packaging bag sealing machine includes a sealing table and a sealing groove opened in the front part of the sealing table. A sealing mechanism is arranged on the top of the sealing table. Both sides of the inner cavity of the sealing groove are rotatably connected with a first threaded rod through openings. One side of the sealing table is fixedly connected with a motor through a fixing frame. The output shaft of the motor is fixedly connected with one end of the first threaded rod through a coupling. Threaded sleeves are threadedly connected to both sides of the outer surface of the first threaded rod. A first sliding groove is opened in the rear part of the inner cavity of the sealing groove. Both sides inside the first sliding groove are slidably connected with the outer surface of the threaded sleeve through sliders. A sliding frame is fixedly connected to the front of the outer surface of the threaded sleeve. A second sliding groove is opened in the rear part of the inner cavity of the sliding frame. A limiting plate is slidably connected to the inside of the second sliding groove through a slider. A spring is fixedly connected between the top of the inner cavity of the sliding frame and the top of the limiting plate.

[0006] Preferably, the sealing mechanism includes a sealing frame fixedly connected to the top of the sealing table. An electric telescopic rod is fixedly installed on the top of the sealing frame through an opening.

Detailed implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a food packaging bag sealing machine, including a sealing table 1 and a sealing groove 2 opened in the front of the sealing table 1. A sealing mechanism 3 is provided on the top of the sealing table 1. The sealing mechanism 3 includes a sealing frame 31. The sealing frame 31 is fixedly connected to the top of the sealing table 1. An electric telescopic rod 32 is fixedly installed on the top of the sealing frame 31 through an opening. The electric telescopic rod 32 is electrically connected to an external power supply and is controlled by a control switch. The telescopic end of the electric telescopic rod 32 is fixedly connected to a heat-sealing plate 33. The heat-sealing plate 33 is electrically connected to an external power supply and is controlled by a control switch. An electric heating plate 34 is fixedly installed inside the heat-sealing plate 33. Both sides of the inner cavity of the sealing groove 2 are rotatably connected to a first threaded rod 4 through openings. The thread directions on both sides of the surface of the first threaded rod 4 are opposite. One side of the sealing table 1 is fixedly connected to a motor 5 through a fixing frame. The motor 5 is a servo motor and is electrically connected to an external power supply and is controlled by a control switch. The output shaft of the motor 5 is fixedly connected to one end of the first threaded rod 4 through a coupling. Threaded sleeves 6 are threadedly connected to both sides of the outer surface of the first threaded rod 4. A first chute 7 is opened at the rear of the inner cavity of the sealing groove 2. Both sides inside the first chute 7 are slidably connected to the outer surface of the threaded sleeve 6 through sliders. A sliding frame 8 is fixedly connected to the front of the outer surface of the threaded sleeve 6. A second chute 9 is opened at the rear of the inner cavity of the sliding frame 8. A limiting plate 10 is slidably connected to the inside of the second chute 9 through a slider. A spring 11 is fixedly connected between the top of the inner cavity of the sliding frame 8 and the top of the limiting plate 10.

[0021] It should be noted that after the two limiting plates 10 limit the two corners of the food packaging bag for sealing, the heat-sealing plate 33 seals the bag neck after the corners of the food packaging bag. The heat-sealing plate 33 is made of aluminum and has good heat conduction effect.

[0022] Further, to facilitate the support of the packaging bag, a fixed plate 12 is fixedly connected to the bottom of the sealing table 1, a bottom plate 13 is fixedly connected to the bottom of the fixed plate 12, a third chute 14 is formed in the front part of the fixed plate 12, a sliding plate 15 is slidably connected to the inside of the third chute 14 through a slider, a support plate 16 is fixedly connected to the front part of the sliding plate 15, a second threaded rod 17 is rotatably connected to the bottom of the sealing table 1 through a bearing, one end of the second threaded rod 17 penetrates through the sliding plate 15 and extends below the sliding plate 15, and a threaded opening adapted to the second threaded rod 17 is formed in the top of the sliding plate 15.

[0023] During use, by rotating the second threaded rod 17, the second threaded rod 17 drives the support plate 16 to move upward through the sliding plate 15, moves the support plate 16 upward to a suitable position, places the food packaging bag on the support plate 16, and places the seal of the food packaging bag in the sealing groove 2. By pulling up the two limit plates 10 respectively, place the two corners of the seal of the food packaging bag under the limit plates 10 respectively. Through the action of the spring 11, the limit plates 10 are pushed downward to press the corners of the packaging bag for positioning. Then, control the motor 5 to drive the first threaded rod 4 to rotate, the first threaded rod 4 drives the two threaded sleeves 6 to move to both sides, and the threaded sleeves 6 drive the two corners of the packaging bag to be pulled to both sides through the sliding frame 8, pull the seal of the packaging bag flat, and stop the motor 5. By controlling the electric telescopic rod 32 to extend, drive the heat sealing plate 33 to move downward, and at the same time, the electric heating plate 34 heats the heat sealing plate 33, so that the heat sealing plate 33 presses the seal of the packaging bag downward for heat sealing;

[0024] After the packaging bag is sealed, control the electric telescopic rod 32 to drive the heat sealing plate 33 to move upward to reset, and pull up the two limit plates 10, take out the two corners of the packaging bag, and thus take out the sealed packaging bag.
