An electric heating wire 29 is installed inside the heating groove 28, and the opening of the heating groove 28 is connected to a heat transfer plate 30 made of metal.
[0035] In the embodiments of this utility model, reference is made to Figure 1 As shown, there are multiple heating cylinders 10, which are equidistantly distributed on the side of the heating plate 9.

[0046] In the embodiments of this utility model, reference is made to Figure 1 As shown, there are multiple placement slots 4, which are linearly and equidistantly distributed on the top of the placement plate 3.
[0047] It should be noted that by setting multiple placement slots 4, multiple packaging bags can be placed in them, achieving the effect of heat-sealing multiple packaging bags at once, thus improving the efficiency of packaging bag heat sealing.
[0048] In the embodiments of this utility model, reference is made to Figure 4 As shown, the bottom ends of the placement plate 3 are respectively connected to the first limiting block 22 and the second limiting block 25. The first limiting block 22 and the second limiting block 25 are respectively slidably connected to the first limiting groove 5 and the second limiting groove 24. The first limiting groove 5 and the second limiting groove 24 are respectively set at the two ends of the top of the lifting plate 2.
[0049] In the embodiments of this utility model, reference is made to Figure 4 As shown, the first limiting block 22 and the second limiting block 25 are respectively provided with a first limiting hole 23 and a second limiting hole 26 on their sides. The first limiting hole 23 and the second limiting hole 26 are respectively slidably connected to the first limiting shaft 6 and the second limiting shaft. The two ends of the first limiting shaft 6 are respectively connected to the two inner surfaces of the first limiting groove 5, and the two ends of the second limiting shaft are respectively connected to the two inner surfaces of the second limiting groove 24.

[0051] The working principle of the heat sealing machine for pesticide packaging provided by this utility model is as follows:
[0052] The packaging bag is moved to the lower part of the middle of the fixed plate 7 by moving the sliding rail 16. Then, the lifting cylinder 19 is activated, which drives the lifting plate 2 to move downward, thereby driving the sliding rail 16 and the placement plate 3 connected to the lifting plate 2 to move upward until the upper end of the packaging bag is moved between the fixed plate 7 and the heating plate 9. Then, the heating cylinder 10 drives the heating plate 9 to move, applying pressure and heating to the upper end of the packaging bag to heat seal it. After heat sealing, the sealed packaging bag is moved to the loading point by the reverse drive of the lifting cylinder 19 and the sliding rail 16, so that the operator can remove the sealed packaging bag.
