Description

Technical Field

[0001] The utility model relates to the technical field of a device or method for sealing or fastening a folding opening or sealing of a package, in particular to an automatic vacuum packaging machine for fruits. Background Art

[0002] During the transportation of fruits, in order to ensure the freshness of the fruits and facilitate the transportation of the fruits, it is often necessary to vacuum-extract the fruit packaging bags and hot-melt-seal them after the fruits are packaged, thereby reducing the air content in the environment where the fruits are located. This not only facilitates transportation but also reduces the possibility of fruit oxidation. The Chinese utility model patent, authorization announcement number "CN214493576U", discloses a vacuum packaging machine for fruits, including a box body, a limiting device, a vacuum-extracting device and a sealing device. An adjustment plate is provided in the box body, and a left mounting plate and a right mounting plate are symmetrically fixed on the adjustment plate. A limiting device is installed on the side opposite to the left mounting plate and the right mounting plate, and the limiting device includes a limiting cylinder, a left connecting plate, a right connecting plate, a connecting column, a limiting spring and a contact head. The limiting cylinder is fixedly connected to the left mounting plate or the right mounting plate, and the output end of the limiting cylinder is connected to the left connecting plate. One end of the connecting column is fixedly connected to the right connecting plate, and the other end extends outward after passing through the left connecting plate. The limiting spring is connected between the left connecting plate and the right connecting plate and is located on the outside of the connecting column. Contact heads are symmetrically installed on the side of the right connecting plate away from the left connecting plate. A vacuum device is installed in the middle of the top wall of the box body, and a sealing device is installed in the middle of the side wall.

[0003] The above technical solution can not only improve the packaging efficiency, but also effectively fix the fruit to avoid deviation. When the sealing device is sealing, since the packaging bag is relatively soft, when the sealing devices on both sides move relative to each other, the packaging bag is too soft to fall down, resulting in failure to contact with the sealing device, thereby causing sealing failure. In order to solve the above problem, there is an urgent need for a fruit automatic vacuum packaging machine that can prevent the fruit packaging bag from being adsorbed on the fruit and affecting the sealing of the sealing device.

[0024] See also Figure 1-4 The utility model provides a technical solution: a fruit automatic vacuum packaging machine, comprising a packaging workbench 1 and a clamping assembly, wherein a support plate 17 is welded to the upper surface of the packaging workbench 1, and a rod 18 is welded to the surface of the support plate 17;

[0025] The clamping assembly is arranged on the rod 18, and the clamping assembly includes a fixed clamping member 5, a hole 8, a threaded column 2 9, a circular ring member 10, a spring 11, an internal threaded sleeve 12, a circular ring member 13 and a movable clamping member 14. The fixed clamping member 5 slides along the surface of the rod 18, and the movable clamping member 14 slides along the surface of the fixed clamping member 5. The hole 8 is opened on the movable clamping member 14, and the threaded column 2 9 is welded to the fixed clamping member 5. The threaded column 2 9 passes through the hole 8, and the threaded column The size of the second 9 is smaller than the inner diameter of the hole 8. The inner surface of the internal threaded sleeve 12 is threadedly connected to the surface of the threaded column second 9. The circular ring member 13 is fixedly sleeved on the internal threaded sleeve 12. The inner diameter of the circular ring member 13 is smaller than the outer diameter of the circular ring member 10. The outer diameter of the circular ring member 13 is larger than the inner diameter of the hole 8. The circular ring member 10 rotates inside the hole 8. The inner diameter of the circular ring member 10 is larger than the size of the threaded column second 9. There are multiple clamping components, and the multiple clamping components are all arranged on the rod 18.

[0026] One end of the plurality of springs 11 is welded to the surface of the corresponding internal threaded sleeve 12, and the other end of the plurality of springs 11 is welded to the corresponding circular ring member 10.

[0027] The plurality of circular ring members 10 rotate inside the corresponding holes 8 respectively, and the surfaces of the plurality of fixing clamping members 5 are all threadedly connected with threaded columns 6.

[0028] The surfaces of the plurality of threaded columns 6 are all welded with knobs 7 , and the surfaces of the plurality of threaded columns 6 are all in contact with the surface of the rod 18 .

[0029] An air pump 4 is mounted on the upper end of the support plate 17 via screws. An output end of the air pump 4 is connected to a pipe 3 , and the other end of the pipe 3 is fixed to the support plate 17 .

[0030] A plurality of electric telescopic rods 16 are fixedly connected to opposite surfaces of the support plate 17 , an electric heating cutter 15 is fixedly connected to opposite surfaces of the electric telescopic rods 16 , and a vacuum cover 2 is rotatably connected to the surface of the packaging workbench 1 .

[0031] It should be noted that: in the initial state, the spring 11 is in a compressed state.

[0032] When the fruit needs to be vacuum packed;

[0033] First, the vacuum cover 2 is rotated to open, and then the upper end of the bag with the packed fruit is driven by an external force to move between the corresponding movable clamping member 14 and the fixed clamping member 5. Multiple springs 11 are reset to drive the corresponding movable clamping member 14 to clamp the upper end of the packaging bag. Then, the circular ring member 13 is driven by an external force to rotate and the internal threaded sleeve 12 moves close to the movable clamping member 14 until the circular ring member 13 contacts the movable clamping member 14. At this moment, the movable clamping member 14 is subjected to the locking force of the threaded column 2 9.

[0034] Secondly, the vacuum cover 2 is turned to close and the air pump 4 is turned on. The start of the air pump 4 drives the pipe 3 to absorb the air in the packaging bag. After the air in the packaging bag is vacuumed, the two electric heating cutters 15 and multiple electric telescopic rods 16 are started. The multiple electric telescopic rods 16 respectively drive the corresponding electric heating cutters 15 to move relative to each other to heat-melt and seal the packaging bag.

[0035] When it is necessary to adjust the position of the fixing clamp 5 on the rod 18;

[0036] First, the knob 7 is driven to move by an external force, and the movement of the knob 7 drives the threaded column 6 to move to loosen the positional relationship between the fixed clamp 5 and the rod 18. Then, the fixed clamp 5 is driven to move along the rod 18 to a suitable position by an external force, and then the knob 7 is driven to move by an external force to drive the threaded column 6 again to tighten the relationship between the fixed clamp 5 and the rod 18.

[0037] By providing the movable clamping member 14 and the fixed clamping member 5 in the clamping assembly, the movable clamping member 14 and the fixed clamping member 5 can clamp the fruit packaging bag, thereby preventing the fruit packaging bag from being adsorbed on the fruit, resulting in the two electric heating cutters 15 being unable to contact the packaging bag during sealing, thereby ensuring the stability of the fruit packaging during sealing.

[0038] By setting up multiple clamping components, since different fruits require fruit packaging bags of different sizes, in order to adapt to the clamping work of fruit packaging bags of different sizes, the clamping components can select an appropriate number to clamp the fruit packaging bags according to needs, avoiding the problem that the fruit packaging bags are too large and only the two ends are clamped, which makes it difficult to ensure that the middle part of the packaging bag will not fall off and affect the sealing. That is, it ensures that fruit packaging bags of different sizes can be sealed.

[0039] Working principle:

[0040] When the fruit needs to be vacuum packed;

[0041] First, the vacuum cover 2 is rotated to open, and then the upper end of the bag with the packed fruit is driven by an external force to move between the corresponding movable clamping member 14 and the fixed clamping member 5. Multiple springs 11 are reset to drive the corresponding movable clamping member 14 to clamp the upper end of the packaging bag. Then, the circular ring member 13 is driven by an external force to rotate and the internal threaded sleeve 12 moves close to the movable clamping member 14 until the circular ring member 13 contacts the movable clamping member 14. At this moment, the movable clamping member 14 is subjected to the locking force of the threaded column 2 9.

[0042] Secondly, the vacuum cover 2 is turned to close and the air pump 4 is turned on. The start of the air pump 4 drives the pipe 3 to absorb the air in the packaging bag. After the air in the packaging bag is vacuumed, the two electric heating cutters 15 and multiple electric telescopic rods 16 are started. The multiple electric telescopic rods 16 respectively drive the corresponding electric heating cutters 15 to move relative to each other to heat-melt and seal the packaging bag.

[0043] When it is necessary to adjust the position of the fixing clamp 5 on the rod 18;

[0044] First, the knob 7 is driven by an external force to move, and the knob 7 drives the threaded column 6 to move to loosen the position relationship between the fixed clamp 5 and the rod 18. Then, the fixed clamp 5 is driven by an external force to move along the rod 18 to a suitable position, and then the knob 7 is driven by an external force to move, and the threaded column 6 is driven again to tighten the relationship between the fixed clamp 5 and the rod 18.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
