Description

Technical Field

[0001] The utility model relates to the technical field of plastic product packaging and processing, in particular to a plastic product packaging edge sealing device. Background Art

[0002] In modern life, the use of plastic products has made daily life more convenient. Plastic bags, in particular, are relatively inexpensive and offer businesses a nearly free packaging option, leading to their widespread use. Plastic products are a general term for household and industrial products made primarily from plastic. This encompasses products made using all processes, including injection molding and blister molding. Plastic is a type of synthetic polymer material with plasticity.

[0003] Currently, small plastic products are typically packaged in plastic bags or other packaging after production and processing, and then sealed. However, after sealing, the seal is often still at high temperatures. When excessive gas accumulates inside the bag, the high temperature causes the gas to expand, potentially opening the seal that has not yet fully solidified. This can lead to seal failure, air leakage, and poor processing quality. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a plastic product packaging edge sealing device, which aims to improve the problem of edge sealing failure caused by internal gas expansion in the plastic product edge sealing process in the prior art, thereby affecting the processing quality.

[0005] The top of the operating table is provided with a heat sealing mechanism, and the middle end of the top of the operating table is provided with a positioning mechanism. The top of the operating table is provided with a slide groove near the heat sealing mechanism. The top of the operating table is fixedly connected to a mounting base near one end of the slide groove, and one side of the mounting base is fixedly connected to an electric push rod, and the driving end of the electric push rod is fixedly connected to an L-shaped air outlet pipe below the outer wall of the L-shaped air outlet pipe. A connecting rod is fixedly connected to the inside of the slide groove, and a pressure wheel is provided in the middle of the outer circumference of the pressure wheel. An annular groove is provided at the bottom end of the connecting rod is rotatably connected to the inside of the annular groove through a rotating ring.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-5, The utility model provides an embodiment: a plastic product packaging edge sealing device, including an operating table 1, a heat sealing mechanism is provided on the top rear side of the operating table 1, the heat sealing mechanism includes a vertical plate 2, the bottom of the vertical plate 2 is installed on the top rear side of the operating table 1, the front top of the vertical plate 2 is fixedly connected to the top plate 3, the bottom middle end of the top plate 3 is fixedly connected to the cylinder 4, the bottom driving end of the cylinder 4 is fixedly connected to the heat sealing head 5, and a positioning mechanism is provided at the top middle end of the operating table 1. The positioning mechanism includes a motor 10 and two square sliding holes 7, the two square sliding holes 7 are symmetrically arranged at the top middle end of the operating table 1, the inner sliding holes of the square sliding holes 7 are slidably connected to the slider 8, the top of the slider 8 is fixedly connected to the L-shaped push plate 6, the motor 10 is installed on one side of the bottom of the operating table 1, and the driving end of the motor 10 is fixedly connected to the bidirectional threaded rod 9. The two sliders 8 are respectively threadedly connected to the outer sides of the bidirectional threaded rod 9. A slide groove 19 is provided at the top of the operating table 1 near the heat sealing mechanism. A mounting seat 11 is fixedly connected to one end of the top of the operating table 1 near the slide groove 19. An electric push rod 12 is fixedly connected to one side of the mounting seat 11. The driving end of the electric push rod 12 is fixedly connected to an L-shaped air outlet pipe 13. A connecting rod 14 is fixedly connected to the lower part of the outer wall of the L-shaped air outlet pipe 13. A pressure wheel 15 is provided inside the slide groove 19, and an annular groove 16 is provided in the middle part of the outer periphery of the pressure wheel 15. The bottom end of the connecting rod 14 is rotatably connected to the inside of the annular groove 16 through a rotating ring. An air cooler 17 is installed at one end of the rear side of the operating table 1. The output port of the air cooler 17 is connected to the inside of the L-shaped air outlet pipe 13 through an air supply pipe 18. Support legs are installed at the four corners of the bottom of the operating table 1. The plastic package is placed on the top of the operating table 1, the motor 10 is started, driving the bidirectional threaded rod 9 to rotate, so that the sliders 8 on both sides are close to each other, and the L-shaped push plates 6 on both sides are close to each other, so that the packaging bag is centered. At this time, the seal of the packaging bag is just above the slide 19, and then the cylinder 4 drives the heat sealing head 5 to move downward, pressing the seal of the packaging bag into the slide 19 to complete the heat plastic sealing. Then the heat sealing head 5 retracts. At this time, the seal of the packaging bag is in the slide 19, and then the electric push rod 12 drives the L-shaped air outlet pipe 13 to move toward the packaging bag. At the same time, the cold air generated by the cooling fan 17 enters the L-shaped air outlet pipe 13 through the air supply pipe 18 and is discharged. When passing through the seal of the packaging bag, it is quickly cooled. Then the L-shaped air outlet pipe 13 continues to move forward, driving the pressure wheel 15 to crush the seal, ensuring that the seal is quickly cooled and solidified, improving the reliability of the edge sealing, and avoiding air leakage.

[0027] The output end of the L-shaped air outlet pipe 13 is facing the inside of the chute 19, and the cold air ejected from the bottom of the L-shaped air outlet pipe 13 is directly sprayed into the inside of the chute 19, thereby cooling and solidifying the seal inside it. The heat sealing head 5 is facing the chute 19, and the heat sealing head 5 presses the seal of the plastic product into the chute 19 for heat sealing. The width of the heat sealing head 5 is less than or equal to the width of the chute 19, and the width of the pressure wheel 15 is equal to the width of the chute 19, so that the pressure wheel 15 will not shake during the movement process, and it will be more stable, so that the seal can be crushed more steadily and the effect is better.

[0028] Working principle: First, place the plastic package on the top of the operating table 1, start the motor 10, and drive the bidirectional threaded rod 9 to rotate, so that the sliders 8 on both sides are close to each other, and the L-shaped push plates 6 on both sides are close to each other, so that the packaging bag is centered. At this time, the seal of the packaging bag is just above the slide 19, and then the cylinder 4 drives the heat sealing head 5 to move downward, pressing the seal of the packaging bag into the slide 19 to complete the heat plastic sealing. Then the heat sealing head 5 retracts. At this time, the seal of the packaging bag is in the slide 19, and then the electric push rod 12 drives the L-shaped air outlet pipe 13 to move toward the packaging bag. At the same time, the cold air generated by the cold air fan 17 enters the L-shaped air outlet pipe 13 through the air supply pipe 18 and is discharged. When passing through the seal of the packaging bag, it is rapidly cooled, and then the L-shaped air outlet pipe 13 continues to move forward, driving the pressure wheel 15 to crush the seal, ensuring that the seal is quickly cooled and solidified, improving the reliability of the edge sealing, and avoiding air leakage.
