Description

Technical Field

[0001] The utility model belongs to the technical field of bagging machines and provides a bag opening sealing device for a young fruit bagging machine. Background Art

[0002] Bagging is a common fruit-growing practice. This involves bagging young fruit in specialized fruit bags, which allow them to grow normally within the bags. This effectively reduces the risks and disadvantages of insect bites. The bag also leaves room for the young fruit, ensuring they grow naturally in a safe environment until they mature. Bagging machines are used to mechanized, streamlined bagging of large quantities of young fruit, sealing the bags simultaneously. This replaces the traditional manual bagging process.

[0003] According to the utility model with authorization announcement number CN 218571011 U, a bag sealing device for a young fruit bagging machine has an incomplete structural design during the sealing process. The claw structure opens and closes to clamp the bag opening of the fruit bag, which inevitably causes wrinkles in the fruit bag during the bagging process. The wrinkled fruit bag surface becomes uneven, making the bag opening uneven and misaligned. When sealing, the bag opening cannot be fully and tightly closed, resulting in open gaps in some parts of the bag opening. External insects will enter the fruit bag through the gaps and cause damage to the young fruit, thereby reducing the sealing effect of the fruit bag on the young fruit. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and solve the problem that the bag opening of the fruit bag is not tightly sealed by the bag opening sealing device used in the existing young fruit bagging machine.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a bag sealing device for a young fruit bagging machine, comprising a first clamping claw and a second clamping claw that intersect each other, a central axis being rotatably connected at the intersection between the first clamping claw and the second clamping claw, a second bracket being fixedly connected to the upper end of the first clamping claw, and the first bracket being fixedly connected to the upper end of the second clamping claw;

[0006] A pair of first sealing supports located above the first half ring are fixedly connected to the upper end of the first bracket, and the two first sealing supports are arranged up and down, and a heating plate is fixedly connected between the two first sealing supports;

[0007] A pair of second sealing supports located above the second half ring are fixedly connected to the upper end of the second bracket, and the two second sealing supports are arranged up and down. A slider is slidably connected between the two second sealing supports, and a round roller is rotatably connected in the middle of the slider, and the surface of the round roller is in contact with the surface of the heating plate.

[0008] In a preferred technical solution of the present invention, a return spring is fixedly connected between the inner ends of the first clamping claw and the second clamping claw and below the central axis.

[0009] In a preferred technical solution of the present invention, the rear end of the slider is fixedly connected to a push-pull rod, the rear end of the push-pull rod is transmission-connected to a linear motor, and the linear motor is fixedly connected to any one of the second sealing support surfaces.

[0010] In a better technical solution of the present invention, the lower end of the first clamping claw is fixedly connected to a bracket, the inner end of the bracket and adjacent to the lower end of the first clamping claw is fixedly connected to an electromagnet, the electromagnet has a cylindrical shape, and a buffer spring is provided on the outer surface of the electromagnet, the right end of the buffer spring is fixedly connected to a buffer plate located on the right side of the electromagnet, the left end of the buffer spring is fixedly connected to the inner end of the bracket, the buffer spring is made of spring steel, the buffer plate is made of magnesium-aluminum alloy, and the lower end of the second clamping claw is fixedly connected to an iron block.

[0011] In a preferred technical solution of the present invention, the inner end of the first bracket is fixedly connected to a first half ring, the inner end of the second bracket is fixedly connected to a second half ring, and the first half ring and the second half ring are tightly fastened to each other.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] After the electromagnet is powered off, it loses its magnetism, and the return spring relies on its own elastic force to rotate the first clamping claw and the second clamping claw along the central axis and fork each other in an X shape. The buffer spring relies on its own elastic force to push the buffer plate out of the iron block, so that the iron block is quickly separated from the electromagnet. The first half ring and the second half ring are separated from each other, and the first sealing support and the second sealing support are separated from each other, thereby revealing the heating plate and the round roller, so that the bag opening of the fruit bag is placed between the first bracket and the second bracket, so that the bag opening sealing part of the fruit bag is located between the heating plate and the round roller;

[0014] When the electromagnet is energized, it will generate magnetic attraction to the iron block, which will stick to the buffer sheet. The iron block will push the buffer sheet to stick to the surface of the electromagnet, and the buffer sheet will buffer the iron block to prevent it from damaging the electromagnet, causing the buffer spring and the return spring to shrink. The first clamping claw and the second clamping claw will close together along the center axis, and the first half ring and the second half ring will close together and be tightly fastened. The first sealing support and the second sealing support will stick together as a whole, and the heating plate will overlap with the circular roller at the sealing point of the fruit bag, so that the fruit bag will be clamped between the first sealing support and the second sealing support. The linear motor will drive the circular roller to roll back and forth along the surface of the fruit bag to eliminate wrinkles on the surface of the fruit bag. The surface of the heating plate will heat up and melt the sealing point of the fruit bag to close it tightly. It is advisable to apply glue to the surface of the heating plate in advance to make the sealing point of the fruit bag more tightly closed, thereby enhancing the sealing performance of the sealing point of the fruit bag.

The bracket 4 is installed on the young fruit bagging machine so that the entire device and the young fruit bagging machine are combined into one, and an external power supply supplies power to the electromagnet 5, the linear motor 15, and the heating plate separately. Independent power supply switches are separately set for the electromagnet 5, the linear motor 15, and the heating plate. First, before use, it is necessary to power off the magnet, the linear motor 15, and the heating plate respectively.

[0022] The electromagnet 5 is cylindrical in shape, and a buffer spring 6 is set into the outer surface of the electromagnet 5. The right end of the buffer spring 6 is fixedly connected to a buffer plate 7 located on the right side of the electromagnet 5. The left end of the buffer spring 6 is fixedly connected to the inner end of the bracket 4. The buffer spring 6 is made of spring steel, and the buffer plate 7 is made of magnesium-aluminum alloy. The lower end of the second clamping claw 2 is fixedly connected to an iron block 8. When the electromagnet 5 is energized, magnetic force will be generated to attract the iron block 8. The iron block 8 is close to the electromagnet 5, and the iron block 8 is close to the buffer plate 7. The iron block 8 presses the buffer plate 7 to the surface of the electromagnet 5. The buffer plate 7 compresses the buffer spring 6 and shortens it. The buffer spring 6 has a rebound effect. After the electromagnet 5 is powered off, the electromagnet 5 loses its magnetism, and the electromagnet 5 cannot continue to maintain the magnetic attraction force on the iron block 8. The electromagnet 5 cannot continue to attract the iron block 8. A return spring 20 is fixedly connected between the inner end of the first clamping claw 1 and the inner end of the second clamping claw 2 and below the central axis 3. The return spring 20 was originally clamped by the first clamping claw 1 and the second clamping claw 2 and compressed. The return spring 20 is compressed by the first clamping claw 1 and the second clamping claw 2 and has a rebound elastic force. The return spring 20 will rebound and stretch by its own elastic force, and the return spring 20 will pull the first clamping claw 1 and the second clamping claw 2 along the center The shaft 3 rotates, the first clamping claw 1 and the second clamping claw 2 fork in an X shape, the iron block 8 is separated from the buffer sheet 7, the buffer sheet 7 loses the pressure of the iron block 8 and no longer squeezes the buffer spring 6, the buffer spring 6 loses the squeezing force of the buffer sheet 7, the buffer spring 6 rebounds and stretches to push the buffer sheet 7 to the right, the buffer spring 6 relies on its own elastic force to push the buffer sheet 7 out of the iron block 8 and the iron block 8 is quickly separated from the electromagnet 5, the first clamping claw 1 and the second clamping claw 2 are forked in an X shape along the central axis 3, the first bracket 9 and the second bracket 19 are separated, and the inner end of the first bracket 9 is fixedly connected to the first half ring 10. The inner end of the second bracket 19 is fixedly connected to the second half ring 11. The first half ring 10 and the second half ring 11 are tightly fastened to each other. The first half ring 10 and the second half ring 11 are separated from each other, and the first sealing support 12 and the second sealing support 13 are separated from each other, thereby revealing the heating plate 14 and the round roller 17. This device is extended to place the fruit bag above the first half ring 10 and the second half ring 11, so that the bag opening of the fruit bag is placed between the first bracket 9 and the second bracket 19, so that the sealing portion of the bag opening of the fruit bag is located between the heating plate 14 and the round roller 17, and the bag opening of the fruit bag is located between the first sealing support 12 and the second sealing support 13.

[0023] When the electromagnet 5 is energized, it will generate a magnetic attraction to the iron block 8, which will attract the iron block 8. The iron block 8 will be tightly attached to the buffer sheet 7. The iron block 8 will push the buffer sheet 7 to the surface of the electromagnet 5. The buffer sheet 7 will squeeze the buffer spring 6 to the left and shrink it to become shorter. The buffer spring 6 will reset. The buffer sheet 7 will be between the iron block 8 and the electromagnet 5. The buffer sheet 7 will form a separation layer structure between the iron block 8 and the electromagnet 5. The buffer sheet 7 will buffer the iron block 8 to prevent the iron block 8 from damaging the electromagnet 5.

[0024] Because the electromagnet 5 attracts the iron block 8, the first clamping claw 1 and the second clamping claw 2 are closed together along the central axis 3, so that the buffer spring 6 and the return spring 20 shrink, the first bracket 9 and the second bracket 19 will be parallel to each other, the first half ring 10 and the second half ring 11 are closed and fastened to each other, the first sealing support 12 and the second sealing support 13 are tightly attached to each other as a whole, the heating plate 14 and the round roller 17 are tightly attached to the surface of the bag mouth of the fruit bag, and the fruit bag is clamped between the first sealing support 12 and the second sealing support 13. The first half ring 10 and the second half ring 11 keep the bottom of the fruit bag upward, and the heating plate 14 coincides with the round roller 17 at the sealing point of the fruit bag. The linear motor 15 is powered on and the linear motor 15 drives the push-pull rod 16 to slide the slider 18 back and forth along the surface of the second sealing support 13. The round roller 17 rotates as the slider 18 slides, and the round roller 17 moves back and forth along the surface of the fruit bag. Rolling, the round roller 17 rolls the fruit bag mouth flat, the round roller 17 eliminates the wrinkles on the fruit bag surface, the surface of the heating plate 14 heats up and heats and melts the fruit bag mouth seal, and the heating temperature can be controlled by controlling the current and voltage input to the electric heating plate (generally, the heating temperature of the heating plate 14 is controlled at about 25 degrees Celsius, and the actual temperature is adjusted according to actual conditions). The fruit bag mouth seal becomes softened and adheres tightly together. It is advisable to apply glue to the fruit bag mouth seal in advance, and rely on the heating plate 14 to heat the glue and the round roller 17 to roll the glue to improve the tightness of the fruit bag mouth seal. It is advisable to apply glue to the surface of the heating plate 14 in advance to make the fruit bag mouth seal more tightly closed, thereby enhancing the sealing performance of the fruit bag mouth seal, completing the sealing of the fruit bag mouth seal, making the young fruit tightly sealed inside the fruit bag, and avoiding damage to the young fruit caused by a loose bag seal.

[0025] Repeat the above steps, again allowing the first clamping claw 1 and the second clamping claw 2 to fork apart from each other along the central axis 3 in an X-shaped distribution, separate the first bracket 9 and the second bracket 19, separate the first sealing bracket 12 and the second sealing bracket 13, and separate the first half ring 10 and the second half ring 11, so that the device can be detached from the surface of the fruit bag.
