Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a fully automatic reciprocating high-speed packaging machine. Background Technology

[0002] Heat shrink packaging machines, also known as shrink wrapping machines, are one of the more advanced packaging methods on the market. In addition to their own advantages, they can also reduce the possibility of products being opened or stolen.

[0003] The existing publicly available technology, application number CN202420221257.9, describes a reciprocating high-speed automatic heat shrink packaging machine. This machine uses a motor to drive gears, which in turn drive multiple pins to mesh. These pins then drive the gears to move left and right, which in turn drive the motor. The motor then drives a support frame to move left and right. A first slider and a first slide rod support and guide the movement of the support frame. The support frame drives the air outlet pipe to move, evenly blowing hot air onto the packaging film. This ensures the film is heated uniformly, thus maintaining the heat shrink effect and enabling high-speed heat shrinking.

[0004] However, the aforementioned patent still has certain drawbacks in its use: although it can remove dust and other impurities through the suction it generates, it lacks measures to limit the position of items during suction, making it easy for items to be sucked up due to the suction, which in turn affects subsequent normal operation. At the same time, the hot air used for heat shrinking is only turned on at a single location, which causes the shrinkage degree of the packaging film at different distances to change under the action of hot air, thus affecting the overall heat shrinking effect. In addition, the uncontrollable air volume intensity will also cause different degrees of heat to be received at different locations, which will further affect the overall heat shrinking quality, resulting in a less than ideal packaging effect of the device.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0008] (II) Technical Solution

[0009] To achieve the advantages of good heat shrinkage effect, dust removal limiting, and uniform heat shrinkage air volume, the specific technical solution adopted by this utility model is as follows:

[0010] A fully automatic reciprocating high-speed packaging machine includes a base, a packaging box, and a heat shrink box. The packaging box and heat shrink box are respectively installed on the top two sides of the base. A support is located at the bottom of the packaging box and heat shrink box. An electric conveyor belt is installed on the surface of the support. A drive plate is installed directly above the electric conveyor belt at the center of the heat shrink box surface. A bidirectional lead screw is installed inside the drive plate. One end of the bidirectional lead screw passes through the heat shrink box and connects to a motor. A movable seat is symmetrically sleeved around the outer periphery of the bidirectional lead screw. Several sets of hot air nozzles are installed at the bottom of the movable seat. A heating folding pipe is installed at the top of the movable seat. A diverter seat is installed at the top of the heating folding pipe. A diverter port is symmetrically located on both sides of the center of the diverter seat. An adjusting disc is attached to the surface of the diverter port. The adjusting disc is rotatably connected to the diverter seat. One end of the adjusting disc passes through one side of the diverter seat and connects to a motor.

[0011] Furthermore, guide plates are symmetrically installed directly above the top of the electric conveyor belt inside the packaging box, and dust removal plates are slidably connected between the guide plates. Cylinders are symmetrically installed on both sides of the top of the dust removal plates, pressure strips are symmetrically installed on both sides of the bottom of the dust removal plates, and a suction port is provided in the middle of the bottom surface of the dust removal plates.

[0012] Furthermore, a blower and a heating box are installed at the top of the heat shrink box. The heating box is connected to the blower through a pipe.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a fully automatic reciprocating high-speed packaging machine, which has the following beneficial effects:

[0020] (1) This utility model adopts an adjusting plate and a two-way screw. During packaging, the moving seat on the surface of the two-way screw moves back and forth, so that the hot air nozzle can spray out hot air. Since there are two sets of moving seats symmetrically arranged and they can move synchronously, both sides of the item can be heated at one time, thus avoiding the phenomenon of uneven heating caused by unidirectional heating. In addition, the pipe used to introduce hot air is also equipped with an adjusting plate. The openings of different sizes on the surface of the adjusting plate are in contact with the diversion port, thereby changing the amount of hot air flowing out. By controlling the amount of hot air, the amount of hot air from the hot air nozzle can be more controllable, so that the hot air is blown evenly on the packaging film, which makes it easy for the packaging film to be heated evenly. It can achieve high-speed heat shrinkage and has the advantages of good heat shrinkage effect and uniform heat shrinkage air volume.

[0021] (2) This utility model uses pressure strips. When the pallet moves to the position directly below the dust removal plate, the operation of the cylinder can drive the dust removal plate to move downward along the guide plate. At this time, the pressure strips on both sides of the bottom of the dust removal plate will come into contact with the packaged items, and then fix the items by squeezing. This prevents the items from being sucked up when the gas is drawn or from moving and misaligning, ensuring the subsequent packaging effect. It has the advantage of dust removal and positioning.

[0032] In one embodiment, guide plates 30 are symmetrically installed directly above the top of the electric conveyor belt 6 inside the packaging box 7. Dust removal plates 25 are slidably connected between the guide plates 30. Cylinders 28 are symmetrically installed on both sides of the top of the dust removal plates 25.

A suction port 29 is provided in the middle of the bottom surface of the dust removal plates 25.

[0033] In one embodiment, a blower 22 and a heating box 18 are installed at the top of the heat shrink box 8. The heating box 18 is connected to the blower 22 through a pipe. An electric heating wire 19 is installed inside the heating box 18. The top of the heating box 18 is connected to the distributor seat 21 through a heating pipe 17.

[0034] In one embodiment, an exhaust fan 23 and a dust collection box 27 are installed on the top of the packaging box 7. The dust collection box 27 is equipped with a filter screen 24. The top of the dust collection box 27 is connected to the dust collection plate 25 through an exhaust folding pipe 26. The filter screen 24 is set to block dust and prevent dust from entering the exhaust fan 23 and causing damage to the equipment, thus ensuring the safety of the overall structure.

[0035] In one embodiment, a frame 4 is installed at the top of the electric conveyor belt 6, and a pallet 5 is installed at the top of the frame 4. The pallet 5 is provided to facilitate the carrying of items to be packaged, and to facilitate subsequent dust removal and heat shrink packaging.

[0036] In one embodiment, slots are provided on the surfaces of both the packaging box 7 and the heat shrink box 8. The slots are provided to facilitate the operation of the electric conveyor belt 6 and the reciprocating movement of the items.

[0037] In one embodiment, the surface of the adjusting disk 12 is provided with several sets of openings, and the size of the openings gradually increases. The change in the size of the openings is to achieve different hot air output effects.

[0038] In one embodiment, the size of the diversion port 20 is the same as the largest opening size on the surface of the regulating plate 12. The size of the diversion port 20 is set to ensure that the hot air can flow smoothly. The size is set to ensure that the hot air discharge diameter can be changed by changing the fit with different openings on the surface of the regulating plate 12, thereby achieving control of the hot air discharge volume and facilitating better heat shrinking of the packaging.

[0039] Working principle: In actual use, the electric conveyor belt 6 transports the pallet 5 to the far right, placing the items requiring heat shrink packaging on top of the pallet 5. Then, the electric conveyor belt 6 slowly transports the items to the left. When it reaches a position directly below the dust removal plate 25, the operation of the cylinder 28 drives the dust removal plate 25 downwards along the guide plate 30. At this point, the pressure strips 3 on both sides of the bottom of the dust removal plate 25 come into contact with the packaged items, thus securing them through compression and preventing them from being sucked up during gas suction. This causes the items to shift and become misaligned, ensuring the subsequent packaging effect. Then, the operation of the exhaust fan 23 generates suction, which draws in the gas inside the box through the suction port 29 on the surface of the dust removal plate 25, thereby removing dust from the surface of the object. At this time, the outer wall of the item will no longer be covered with dust, and the heat shrinking effect will not be affected. Then, the packaging film roller conveys the packaging film to package the item. The electric conveyor belt 6 transports the item into the heat shrink box 8. The electric conveyor belt 6 stops transporting, and then the operation of the motor 13 drives the bidirectional lead screw 10 to rotate, which causes the moving seat 14 on the surface of the bidirectional lead screw 10 to move back and forth, so that the hot air nozzle 11 at the bottom of the moving seat 14 can spray hot air. Since there are two sets of moving seats 14 symmetrically arranged and they can move synchronously, both sides of the item can be heated at one time, thus avoiding the phenomenon of uneven heating caused by unidirectional heating, so that the packaging film can be heated better. Moreover, there is also an adjustment plate 12 in the pipe used to introduce hot air. The operation of the motor 16 can... The regulating plate 12 is rotated, causing the openings of different sizes on the surface of the regulating plate 12 to contact the diversion port 20, thereby changing the amount of hot air flowing out. By controlling the amount of hot air, the amount of hot air from the hot air nozzle 11 can be made more controllable, thus avoiding uneven heating and evenly blowing hot air onto the packaging film, making it easier for the packaging film to be heated evenly, thus not affecting the heat shrink effect. It can achieve high-speed heat shrink. The device as a whole has the advantages of good heat shrink effect, dust removal limit, and uniform heat shrink air volume.
