[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please refer to Figures 1-5. A high-efficiency preform holder separator includes a base plate 1. A first support 3 is fixedly connected to the top of the base plate 1 via four sets of support rods 2. The four sets of support rods 2 stably support the first support 3 next to the plastic bottle production line. A second support 4 is installed inside the first support 3. A forward / reverse cylinder 5 is installed on one side of the first support 3. One end of the output shaft of the forward / reverse cylinder 5 extends into the interior of the first support 3 and connects to the second support 4. When the forward / reverse cylinder 5 is activated, the output shaft of the forward / reverse cylinder 5 will perform a forward and backward extension movement, thereby driving the second support 4 inside the first support 3 to move horizontally towards or away from the production line. The second support 4 is internally designed with... A fixed plate 6 and a movable plate 7 are provided. The fixed plate 6 is fixedly installed inside one side of the second support 4. A separation cylinder 8 is installed inside the second support 4. One end of the output shaft of the separation cylinder 8 is fixedly connected to the movable plate 7. During the forward and backward extension and retraction of the output shaft of the separation cylinder 8, it can drive the movable plate 7 inside the second support 4 to move horizontally towards or away from the fixed plate 6. A first gripper 9 and a second gripper 10 are respectively connected to the fixed plate 6 and the movable plate 7. The first gripper 9 and the second gripper 10 are arranged side by side at the top of the second support 4. Both of them are provided with arc-shaped grooves 11 at their ends. The arc-shaped grooves 11 match the preform holder on the production line.

[0023] The structure is placed on one side of the plastic bottle production line. When two adjacent sets of preform seats on the production line move to positions directly opposite the first gripper 9 and the second gripper 10, the output shaft of the advance / retreat cylinder 5 is moved forward. At this time, the output shaft of the advance / retreat cylinder 5 controls the second support 4 to move closer to the production line, thereby controlling the first gripper 9 and the second gripper 10 on the second support 4 to move closer to the preforms on the production line. When the output shaft of the advance / retreat cylinder 5 moves to the foremost position, the arc-shaped grooves 11 at the ends of the first gripper 9 and the second gripper 10 will clamp onto the two sets of preforms on the production line. Then, by controlling the output shaft of the separation cylinder 8 to move forward, the movable plate 7 inside the second support 4 will move away from the fixed plate 6 under the driving action of the separation cylinder 8. This causes the second gripper 10 to move away from the first gripper 9 under the drive of the movable plate 7, thus achieving the purpose of automatically separating the two adjacent sets of preform seats on the production line.

[0024] Furthermore, referring to Figures 1-5, a first slide rail 12 is fixedly installed inside the first support 3, a first slider 13 is slidably connected to the first slide rail 12 at the bottom end of the second support 4, a second slide rail 14 is fixedly installed inside the second support 4, and a second slider 15 is slidably connected to the second slide rail 14 at the bottom end of the movable plate 7. When the second support 4 moves horizontally under the driving action of the forward and backward cylinder 5, the first slider 13 will always slide horizontally along the first slide rail 13 under the drive of the second support 4. During this process, the first slide rail 12 and the first slider 13 can guide the movement of the second support 4, ensuring that the movement of the second support 4 is more stable and less prone to deviation. Similarly, when the movable plate 7 moves horizontally under the driving action of the separation cylinder 8, the second slider 15 will always slide horizontally along the second slide rail 14 under the drive of the movable plate 7. During this process, the second slide rail 14 and the second slider 15 can guide the movement of the movable plate 7, ensuring that the movement of the movable plate 7 is more stable and less prone to deviation.

[0025] Furthermore, please refer to Figures 1-5. The inner surface of the arc-shaped groove 11 is provided with a rubber pad 16. During the process of the arc-shaped groove 11 at the end of the first gripper 9 or the second gripper 10 holding the preform seat on the production line, the soft rubber pad 16 can reduce the wear between the arc-shaped groove 11 and the preform seat and avoid scratches on the surface of the preform seat.

[0026] Furthermore, referring to Figures 1-5, the surfaces of both the fixed plate 6 and the movable plate 7 are provided with several sets of threaded heads 17. The first clamp 9 and the second clamp 10 are each provided with several sets of mounting holes 18 for the threaded heads 17 to pass through. When the first clamp 9 and the second clamp 10 are placed on the fixed plate 6 and the movable plate 7, the threaded heads 17 can be aligned and pass through the mounting holes 18 and exposed on the surfaces of the first clamp 9 and the second clamp 10. At this time, the first clamp 9 and the second clamp 10 can be fixed by rotating the nut onto the threaded head 17. Therefore, it is convenient to install and remove the first clamp 9 and the second clamp 10, which makes it easier for workers to replace the first clamp 9 and the second clamp 10 to adapt to different sizes of preform holders.

[0027] Further, please refer to Figures 1-5. The support rod 2 is a telescopic structure composed of a hollow rod 19 and a solid sliding rod 20. A threaded sleeve 21 is fixedly installed at the top of the hollow rod 19, and a screw 22 is threadedly connected to the inside of the threaded sleeve 21. Several sets of insertion holes 23 for one end to be inserted are distributed on the surface of the solid sliding rod 20. By controlling the solid sliding rod 20 to slide up and down inside the hollow rod 19, the overall length of the support rod 2 can be adjusted, thereby adjusting the height position of the first gripper 9 and the second gripper 10. After adjustment, the screw 22 can be screwed into the hollow rod 19 by rotating it. When the end of the screw 22 is inserted into the corresponding insertion hole 23 on the surface of the solid sliding rod 20, the screw 22 will restrict the solid sliding rod 20 from sliding up and down inside the hollow rod 19. At this time, the overall length of the support rod 2 can be kept fixed, so that the first gripper 9 and the second gripper 10 can be fixed at the adjusted height position. Therefore, the device can adapt to production lines of different heights and effectively improve the applicability of the device.

[0028] Furthermore, please refer to Figures 1-5. Four sets of positioning holes 24 are provided at the four corners of the bottom of the base plate 1. When the device is placed next to the production line, the expansion screws can be passed through the positioning holes 24 to keep the base plate 1 fixed, thereby ensuring that the device remains stable and will not be displaced during operation.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
