DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a buffer device for use in a bottle blowing production line includes a mounting frame 1, a conveyor belt 3 is arranged inside the mounting frame 1, a displacement rod 2 is slidably connected inside the mounting frame 1, a fixed frame 9 is fixedly connected to one side of the displacement rod 2, a buffer assembly is arranged inside the fixed frame 9, a second vertical plate 16 is fixedly connected to the bottom of the mounting frame 1, a motor 10 is fixedly installed on one side of the second vertical plate 16, two first vertical plates 12 are fixedly connected to the bottom of the mounting frame 1, and an adjustment assembly is arranged on one side of the two first vertical plates 12.

[0023] First, the preforms are transported via the conveyor belt 3, and then the outer sides of the preforms come into contact with the buffer assembly, which protects the preforms, thereby increasing the stability of transportation and the practicability of the device. Next, the output shaft of the motor 10 is started to rotate according to the sizes of the preforms to drive the adjustment assembly to operate, thereby adjusting the spacing between the buffer assemblies to accommodate the buffer transportation of preforms of different sizes, thereby reducing the limitations of the device.

[0024] like Figure 1-Figure 4 As shown, the adjusting component includes a second bevel gear 14, which is rotatably connected to one side of the second vertical plate 16, one end of the output shaft of the motor 10 is fixedly connected to one end of the rotating shaft of the second bevel gear 14, the adjusting component also includes a first bevel gear 13, the first bevel gear 13 is rotatably connected to one side of the first vertical plate 12, and two brackets 6 are fixedly connected to the outer side of the mounting frame 1, a threaded rod 11 is rotatably connected between one side of the bracket 6 and the first vertical plate 12, one end of the threaded rod 11 is fixedly connected to one end of the rotating shaft of the first bevel gear 13, the first bevel gear 13 is meshed with the second bevel gear 14, a sliding rod 7 is fixedly connected between the two brackets 6, and a displacement block 8 is movably sleeved on the outer side of the sliding rod 7, a threaded groove is provided inside the displacement block 8 and is threadedly connected to the outer side of the threaded rod 11, a displacement groove 5 is penetrated through the top of the bracket 6, and a connecting rod 4 is slidably connected inside the displacement groove 5, the bottom of the connecting rod 4 is fixedly connected to the top of the displacement block 8, and the top of the connecting rod 4 is fixedly connected to the bottom of the displacement rod 2.

[0025] When adjusting the spacing of the buffer assembly, the output shaft of the starting motor 10 is rotated to drive the second bevel gear 14 to rotate and the two first bevel gears 13 to rotate, and then the two threaded rods 11 are rotated and the displacement block 8 is driven to slide on the outside of the slide rod 7. The stability of the movement of the displacement block 8 is increased by the slide rod 7, and then the displacement block 8 moves to drive the connecting rod 4 to slide inside the displacement groove 5, thereby further increasing the smoothness of the movement. Then the connecting rod 4 moves to drive the displacement rod 2 to slide on one side of the mounting frame 1 and drive the buffer assembly inside the fixed frame 9 to move.

[0026] like Figure 1-Figure 4 As shown, the buffer assembly includes a displacement frame 20, which is arranged inside the fixed frame 9. A limiting groove 21 is provided on the outer side of the fixed frame 9. The inner side of the limiting groove 21 is slidably connected to a limiting block 17. One end of the limiting block 17 is fixedly connected to the outer side of the displacement frame 20. The buffer assembly also includes a buffer roller 18, which is rotatably connected to the inside of the displacement frame 20. A stabilizing sleeve 19 is provided on the outer side of the buffer roller 18. A spring 15 is fixedly connected between one side of the displacement frame 20 and the inner wall of the fixed frame 9.

[0027] When the preform contacts the buffer roller 18, the stability of the movement of the preform can be increased by the stabilizing sleeve 19, and then the smoothness of the movement of the preform can be increased by rotating the buffer roller 18. Then the preform contacts the buffer roller 18 to drive the displacement frame 20 to move and at the same time drive the limit block 17 to slide inside the limit groove 21, thereby increasing the stability of the movement of the displacement frame 20. Then the displacement frame 20 moves to compress the spring 15, and under the action of the spring 15, the buffer roller 18 contacts the outside of the preform, thereby better guiding the movement of the preform.

[0028] The utility model provides a buffer device for a bottle blowing production line, and the specific working principle is as follows: first, when adjusting the spacing of the buffer assembly, the second bevel gear 14 is driven to rotate by starting the output shaft of the motor 10, and the two first bevel gears 13 are driven to rotate, and then the two threaded rods 11 are driven to rotate and the displacement block 8 is driven to slide on the outside of the slide rod 7, and the stability of the movement of the displacement block 8 is increased by the slide rod 7, and then the displacement block 8 moves to drive the connecting rod 4 to slide inside the displacement groove 5, thereby further increasing the stability of the movement, and then the connecting rod 4 moves to drive the displacement rod 2 on the mounting frame 1 One side of the bottle blank slides and drives the buffer assembly inside the fixed frame 9 to move at the same time. Finally, when the bottle blank contacts the buffer roller 18, the stability of the bottle blank movement can be increased by the stabilizing sleeve 19. Then, the buffer roller 18 rotates to increase the smoothness of the movement of the bottle blank. Then, the bottle blank contacts the buffer roller 18 to drive the displacement frame 20 to move and drive the limit block 17 to slide inside the limit groove 21, thereby increasing the stability of the movement of the displacement frame 20. Then, the displacement frame 20 moves to compress the spring 15. Under the action of the spring 15, the buffer roller 18 contacts the outside of the bottle blank, thereby better guiding the movement of the bottle blank.
