[0002] Bottle blowing machine is a kind of equipment that uses blow molding process to make plastic preforms into hollow containers through certain process means. Before the preforms are processed into the final products, they need to go through multiple processes and load and flow through multiple components, and the driven bottle clamp is one of them. The driven bottle clamp is used to passively clamp the preform from the previous component and passively release it after it is sent to the next component.

This clamping method is a rigid clamping method, which not only has poor adaptability, but also is prone to the problem of loose clamping after long-term use. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figure 1-4 A self-adaptive driven bottle clamp for a bottle blowing machine comprises a base plate 1, on which two grab bars 2 are symmetrically arranged, and the middle part of the grab bars 2 is rotatably connected to the base plate 1 through a pin shaft 5. The grab bars 2 are defined as an arc rod 4 on one side of the pin shaft 5 and a tail rod 3 on the other side. A thrust spring 10 is provided between the two tail rods 3, and a movable plate 7 is provided between the two grab bars 2. The movable plate 7 is slidably connected to the base plate 1, and the movable plate 7 can approach or move away from the open ends of the two arc rods 4. A pulling component is installed between the base plate 1 and the movable plate 7, and the pulling component can apply a force to the movable plate 7 to move toward the open ends of the two arc rods 4.
[0020] refer to Figure 1 The device is provided with a movable plate 7 between the two gripping rods 2, and the movable plate 7 moves toward or away from the open ends of the two arc-shaped rods 4, and a force is applied to the movable plate 7 to move toward the open ends of the two arc-shaped rods 4 by a pulling assembly. When there is no bottle clamped, refer to Figure 1 The movable plate 7 is located on the side close to the open end of the arc rod 4. When the bottle enters between the two arc rods 4 from the open ends of the two arc rods 4, the gripping rod 2 rotates around the pin 5 under the squeezing effect of the bottle, and the two arc rods 4 open outward, and the bottle enters between the two arc rods 4 and pushes the movable plate 7 to move backward. Since the pulling component applies force to the movable plate 7, the bottle is clamped between the two arc rods 4 and the movable plate 7. The arc rods 4 and the movable plate 7 of the device are both movable structures, which can clamp bottles of different diameters. Moreover, since the movable plate 7 can always generate a thrust on the bottle, the bottle can be clamped more stably between the arc rods 4 and the movable plate 7.
[0021] As an implementation manner, the pulling assembly can exert a force on the movable plate 7 to move toward the open ends of the two arc-shaped rods 4 through gravity.
[0022] Specifically, refer to Figure 2 , Figure 3 , Figure 4 The pulling assembly includes a fixed pulley 14 rotatably connected to the base plate 1. The base plate 1 has a vertical portion 101, and a counterweight block 12 that can move up and down is connected to the vertical portion 101. A pull rope 13 is connected to the counterweight block 12. The other end of the pull rope 13 passes around the fixed pulley 14 and is fixed to one end of the movable plate 7 away from the open ends of the two arc-shaped rods 4. The counterweight block 12 generates a downward pulling force on the pull rope 13. Under the redirection action of the fixed pulley 14, the rope generates a pulling force on the movable plate 7 to move toward the open ends of the two arc-shaped rods 4. The counterweight block 12 is used to apply gravity to generate a pulling force on the movable plate 7. If a spring is used as the power source of the pulling force, the spring will produce irreversible deformation after long-term use, resulting in unstable clamping. The device applies force through the gravity of the counterweight block 12, and will not cause the above-mentioned problem, thereby ensuring that the clamping force remains unchanged for a long time.
[0023] As a sliding connection method, the movable plate 7 is provided with a slideway 8, and the top end of the base plate 1 is slidably connected in the slideway 8.
[0024] In order to reduce the friction between the bottle body and the arc rod when inserting and removing the bottle body, each end of the arc rod 4 is rotatably connected to a first roller 6, and one end of the movable plate 7 close to the open ends of the two arc rods 4 is rotatably connected to a second roller 11. A clamping space 9 is formed between the two first rollers 6 and the second roller 11. When the bottle body is squeezed in, the two first rollers 6 are pushed to expand outward and the second roller 11 is pushed to move backward. When the bottle body is completely squeezed in, the bottle body is limited between the two first rollers 6 and the second roller 11.
[0025] As an implementation mode, the first roller 6 is a cylindrical roller to increase the contact surface with the bottle body.
[0026] A protrusion 15 is fixedly connected to the inner side of one end of the tail rod 3 away from the arc rod 4 , and the thrust spring 10 is limited between the protrusions 15 of the two tail rods 3 . This structure facilitates the installation of the thrust spring 10 .
[0027] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technical solution, concept, and design obtained by equivalent replacement or change based on the technical solution and utility model concept of the utility model by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
