[0039] Embodiment 1

[0040] Please refer to Figure 1-7, A PET preform gate-cutting device, including a base 1 and a cutting knife 44. A first motor 11 is fixedly connected to the inner side surface of the base 1. A conveyor belt 12 is installed at the central position of the inner surface of the base 1. The output end of the first motor 11 is fixedly connected to the transmission shaft of the conveyor belt 12. Four limiting blocks 2 are fixedly connected to the upper surface of the base 1. An adjusting member for adjusting according to different PET preforms is slidably connected to the outer surface of the limiting block 2. A collection channel 3 is fixedly connected to the upper surface of the base 1. Two sliding grooves 31 are opened on the inner side surface of the collection channel 3. A lifting member for adjusting the height of the cutting knife 44 is slidably connected to the inner surface of the two sliding grooves 31. A cutting member is fixedly connected to the lower surface of the lifting member. A recycling member for recycling the cut gate material is slidably connected to the right side of the lower surface of the base 1. The adjusting member includes an adjusting plate 21. The adjusting plate 21 is slidably arranged on the outer surface of the limiting block 2. There are two adjusting plates 21 arranged in a mirror image. Motors 22 are fixedly connected to both sides of the outer surface of the base 1. The output end of the motor 22 extends into the interior of the base 1 and is fixedly connected to a threaded rod 23. A connecting block 24 is threadedly connected to the outer surface of the threaded rod 23. The connecting block 24 is fixedly connected to the lower surface of the adjusting plate 21. The threaded rod 23 is rotatably connected to the base 1. The lifting member includes a lifting plate 32. The lifting plate 32 is slidably arranged on the inner surface of the sliding groove 31. A cylinder 33 is fixedly connected to a corner of the upper surface of the collection channel 3. The output end of the cylinder 33 extends into the interior of the collection channel 3 and is fixedly connected to the lifting plate 32.

[0041] Implementation process: When adjustment is required according to different PET bottles, the two motors 22 start to work to drive the threaded rod 23 to rotate. The rotation of the threaded rod 23 drives the connecting block 24 and the adjusting plate 21 fixedly connected to the connecting block 24 to slide horizontally on the outer surface of the limiting block 2, so that the PET bottle is always at the center position of the conveyor belt 12. When adjusted to the appropriate position, the motor 22 stops working. Subsequently, the cylinder 33 starts to work to drive the lifting plate 32 to slide up and down on the inner surface of the sliding groove 31. The sliding of the lifting plate 32 drives the cutting member to slide synchronously. When the cutting knife 44 in the cutting member slides to the appropriate position, the cylinder 33 stops working.

[0042] Implementation benefits: The distance between the two adjusting plates 21 is adjusted according to PET bottles of different widths, so that the PET bottle is always at the center position of the conveyor belt 12. At the same time, the cutting knife 44 is adjusted according to PET bottles of different heights, so that the device is applicable to PET bottles of different sizes and heights.

[0043] Example 2

[0044] The cutting part includes a mounting plate 4. Both ends of the lower surface of the mounting plate 4 are rotatably connected to a synchronous pulley 41 through a rotating shaft. The outer surfaces of the two synchronous pulleys 41 are meshed and connected with a synchronous belt 42. One end of the lower surface of the mounting plate 4 is fixedly connected with a mount 45. The lower surface of the mount 45 is fixedly connected with a third motor 43. The output end of the third motor 43 extends above the mount 45 and is fixedly connected to the rotating shaft of one synchronous pulley 41.

A fan 51 is installed on the left side of the upper surface of the lifting plate 32. A ventilation opening 52 is formed on the left side surface of the collection channel 3. The fan 51 is inclined.

[0045] Implementation process: After the adjustment is completed, the first motor 11 drives the conveyor belt 12 to start working. Place the PET bottle on the upper surface of the conveyor belt 12 and move along the conveyor belt 12 towards the cutting knife 44. The third motor 43 starts working, and drives the two synchronous pulleys 41 to rotate synchronously through the meshing connection of the synchronous belt 42 and the two synchronous pulleys 41. The rotation of the synchronous pulley 41 drives the cutting knife 44 to rotate synchronously. The fan 51 starts working and blows air towards the surface of the guide plate 5. When the PET bottle contacts the cutting knife 44, the cutting knife 44 cuts off the gate of the PET bottle. The PET bottle continues to move backward under the action of the conveyor belt 12. The cut-off gate falls on the upper surface of the lifting plate 32, and then is blown into the interior of the collection channel 3 along the guide plate 5 under the wind force of the fan 51, and then falls into the interior of the collection box 53 through the collection channel 3.

[0046] Implementation benefits: Recycling the cut-off gate material.
