The forming mechanism, as a part of the triangle packaging machine, is used to hot-melt seal the cylindrical packaging film twice and cut it during the second hot-melt sealing, so that it can produce a product with three faces, each of which is in a triangular shape. However, the existing triangle packaging machine forming mechanism usually drives the entire hot-melt mechanism to rotate through a rotating mechanism after the hot-melt mechanism completes the hot-melt sealing once, and then performs the hot-melt sealing work again after rotation, which increases the steps of the hot-melt sealing work, increases the production difficulty and reduces the production efficiency.

[0032] The support platform 1 is provided with a first driving assembly 4 and a second driving assembly 5 for driving the two groups of hot melt assemblies 2 to move, respectively. The first driving assembly 4 and the second driving assembly 5 are operated and closed in an alternating manner, so that the first hot melt blocks 201 and the second hot melt blocks 202 in the two groups of hot melt assemblies 2 are in a closed and open state in an alternating manner along the diameter direction of the first through hole 3;

[0033] A first strip-shaped gap 6 is arranged in the middle part along the length direction of the first hot melt block 201, and a cutting knife 7 is slidably arranged in the first strip-shaped gap 6.

A second strip-shaped gap 8 is arranged along the length direction of the second hot melt block 202, and the positions of the second strip-shaped gap 8 and the cutting knife 7 correspond.

[0034] By setting up two groups of hot melt components 2 that run alternately, the packaging film can be quickly packaged from two directions to achieve a triangular packaging effect.

[0036] like Figure 5-6 As shown, both ends of the notches in the four fixing blocks 10 are symmetrically provided with cylindrical notches, and the fixing assembly includes eight fixing rods 13 adapted to be arranged in the cylindrical notches, the other ends of the fixing rods 13 on both sides of the first cylinder 401 are fixedly connected to the first hot melt block 201, and the other ends of the fixing rods 13 on both sides of the second cylinder 402 are fixedly connected to the second hot melt block 202;

[0037] A first vertical plate 11 is slidably arranged between the first cylinder 401 and the first hot melt block 201, and the output shaft of the first cylinder 401 passes through the fixed block 10 and is slidably matched with the first vertical plate 11. The first vertical plate 11 is linked with the first cylinder 401 through a fixed component, and the first vertical plate 11 is connected to the first hot melt block 201 through a connecting component; a second vertical plate 12 is slidably arranged between the second cylinder 402 and the second hot melt block 202, and the output shaft of the second cylinder 402 passes through the fixed block 10 and is slidably matched with the second vertical plate 12, and the second vertical plate 12 is fixedly connected to the second hot melt block 202.

[0038] like Figure 7 As shown, the first vertical plate 11 is provided with a second through hole 14 corresponding to and adapted to the position of the output shaft of the first cylinder 401; the connecting assembly includes a first connecting plate 15, the first connecting plate 15 includes an integrally formed vertical portion 1501, a first horizontal portion 1502 arranged at the bottom of the vertical portion 1501 and a second horizontal portion 1503 arranged at the top of the vertical portion 1501, the middle part of the side end surface of the vertical portion 1501 corresponds to the position of the second through hole 14, one end of the cutting knife 7 is fixedly arranged at the top of the first horizontal portion 1502, and the second horizontal portion 1503 is fixedly installed on the top of the first vertical plate 11.

[0039] like Figure 8-9 As shown, the second vertical plate 12 is provided with a third through hole 16 corresponding to and adapted to the position of the output shaft of the second cylinder 402; a second connecting plate 17 is fixedly provided in the middle of the side end surface of the second vertical plate 12 close to the second hot melt block 202, and a fourth through hole 18 is provided in the second connecting plate 17, and the diameter value of the fourth through hole 18 is smaller than the diameter value of the third through hole 16.

[0040] Operation principle: When the triangle packaging machine is in use, the hot melt assembly 2 on a certain diagonal line of the support table 1 starts to operate under the drive of the first driving assembly 4, and the first cylinder 401 and the second cylinder 402 operate synchronously. The output shaft of the first cylinder 401 extends from the cylinder body of the first cylinder 401, passes through the second through hole 14 on the first vertical plate 11, and then abuts against the side end surface of the vertical portion 1501. Then, the output shaft of the first cylinder 401 continues to extend, and then the output shaft of the first cylinder 401 pushes the first connecting plate 15 to move toward the center of the first through hole 3. When the output shaft of the first cylinder 401 When the shaft pushes the first connecting plate 15 so that its vertical portion 1501 coincides with the side end face of the cutting knife 7, the output shaft of the first cylinder 401 that continues to extend will drive the cutting knife 7 to move by pushing the first connecting plate 15. When the output shaft of the first cylinder 401 pushes the first connecting plate 15 so that the side end face of the first horizontal portion 1502 coincides with the side end face of the first hot melt block 201, the output shaft of the first cylinder 401 that continues to be pushed out pushes the first hot melt block 201 to move toward the center of the first through hole 3. At the same time, the output shaft of the second cylinder 402 extends out and passes through the third through hole in the second vertical plate 12. 16 and then extend into the fourth through hole 18 in the second connecting plate 17. At this time, because the diameter of the fourth through hole 18 is smaller than the diameter of the third through hole 16, the output shaft of the second cylinder 402 will move the second vertical plate 12 toward the center of the first through hole 3, and the second connecting block will abut against the side end surface of the second hot melt block 202 to push it, and finally the first hot melt block 201 and the second hot melt block 202 will move synchronously to the diameter where the center of the circle in the first through hole 3 is located. At this time, the packaging film between the first hot melt block 201 and the second hot melt block 202 is heat-sealed, and at the same time, the cutting knife 7 in the first hot melt block 201 is also Move, so it will move from the first strip notch 6 to the second strip notch 8 in the second hot melt plate under the push of the first connecting plate 15, and in this process, the middle part of the heat-sealed part in the packaging film is cut. When the device completes the first cutting, what falls after cutting is waste and can be ignored; the hot melt component 2 on the other diagonal line of the support platform 1 heat-seals and cuts the cylindrical packaging film in the same way. At this time, what falls after cutting is the required triangular packaging bag, and each subsequent alternating operation of the hot melt component 2 can produce a required triangular packaging bag after completing the heat sealing and cutting.
