Description

Technical Field

[0001] The utility model relates to the technical field of bottle making machines, in particular to a clamping mechanism for bottle making machines. Background Art

[0002] The clamping mechanism of the bottle making machine is an important part of the bottle making machine. Its main function is to clamp and fix the clamped parts during the bottle making process, and at the same time, it can realize the opening and closing and self-rotation functions of the chuck. The prior art has two different types of clamping mechanisms installed in the A part and the B part of the bottle making machine respectively, and corresponding opening and closing and self-rotation stop control devices. In the prior art, the chuck claw positioning guide of the clamping mechanism adopts the form of the chuck claw cylinder and the chuck circular hole for guidance. After long-term use, the chuck circular hole and the chuck claw cylinder are prone to wear, affecting the accuracy of bottle making. At the same time, due to the high-temperature flame heating in the bottle making process, carbon is easily deposited between the chuck claw and the chuck cylinder, so it is necessary to frequently add lubricating oil to the chuck claw. After the lubricating oil is added, due to the self-rotation of the clamping mechanism, the lubricating oil often splashes to other parts of the equipment, thereby affecting the product quality. At the same time, since some stations of the bottle making machine need to stop rotating during the bottle making process, a rotation stop control device needs to be set. The current rotation stop control device on the market is mainly realized by setting a clutch between the chuck and the gear, but the current clutch device design on the market is relatively complex and has poor synchronization. At the same time, the current clamping mechanism on the market is a single chuck design, which has poor positioning of the clamped part. Utility Model Content

A spring 2-2 is provided in the middle of the transmission connecting rod 2-4. A clutch 4 is provided below the guide sleeve 2-5. A transmission gear 5 is provided below the clutch 4. The clutch 4 contacts the inner surface of the transmission gear 5 for transmission. When the two are separated, the transmission is disengaged. A protective cover 7 is provided on the outside of the chuck claw. The A-part opening and closing and rotation stop control device 3 includes a clutch separation seat, a guide transmission shaft 3-4 and a clamp opening seat. The clamp opening seat and the clutch separation seat are both connected to the guide transmission shaft 3-4. The interior of the A-part chuck 1-6 is a hollow structure with a central hollow side divided into three equal parts. The sliding groove is installed in conjunction with the guide column 1-9, so that the main chuck jaw 1-10 can slide in the chuck 1-6. The semicircular structure results in only half of the area sliding, and the contact area between the main chuck jaw 1-10 and the guide column 1-9 is smaller, so the two are less likely to get stuck in a high temperature environment, and the wear is smaller. The three main chuck jaws 1-10 cooperate to form a three-jaw self-centering structure, and at the same time, the tail of the main chuck jaw 1-10 is connected to the fine-tuning block 1-7 through an axle pin. Three guide grooves are provided on the main integral adjustment ring 1-5, and the fine-tuning block 1-7 passes through the guide grooves on the main integral adjustment ring 1-5. The upper part is provided with a fine-tuning nut 1-8 and a fine-tuning nut fixing plate 1-11. The relative positions of the three main chuck jaws 1-10 can be fine-tuned by rotating the fine-tuning nut 1-8. After the adjustment is completed, the fine-tuning block 1-7 is locked through the screw hole on the main integral adjustment ring 1-5.

[0031] When it is necessary to significantly adjust the overall opening and closing size of the main chuck jaws 1-10, it is achieved by adjusting the distance between the main integral adjustment ring 1-5 and the jaw opening sleeve 1-4. When the distance between the ears of the main integral adjustment ring 1-5 and the jaw opening sleeve 1-4 is smaller, the initial chuck jaws will open larger, and vice versa. The main integral adjustment ring 1-5 and the fixed ring 1-2 are provided with a main compression spring 1-3, and the main function of the main compression spring 1-3 is to ensure that the main chuck jaws 1-10 are always in a closed state. When the jaws need to be opened, the main integral adjustment ring 1-5 is driven by the jaw opening control device to move upward, and then further drives the main chuck jaws 1-10 to open, realizing the jaw opening action. The fixed ring 1-2 is connected to the connecting sleeve 1-1 by a thread. One end of the connecting sleeve 1-1 is fixedly connected to the claw head 1-6 by a thread. The guide column 1-9 is installed in the semicircular fixing groove inside the A-part chuck 1-6. A semicircular sliding groove is arranged on the side of the main chuck jaw 1-10, and the sliding groove on the main chuck jaw 1-10 is installed in conjunction with the guide column 1-9 to form a sliding assembly. A groove is arranged at the tail of the main chuck jaw 1-10, which is connected to one end of the fine-tuning block 1-7 through an axle pin, and the other end of the fine-tuning block 1-7 is a cylindrical thread. The fine-tuning block 1-7 passes through the main integral adjustment ring 1-5 and is fixed by the fine-tuning nut 1-8 and the fine-tuning nut fixing plate 1-11. The main integral adjustment ring 1-5 is connected to the open jaw sleeve 1-4 through a thread, and a main compression spring 1-3 is arranged above the open jaw sleeve 1-4. The main compression spring 1-3 is fixed by a fixing ring 1-2, and the fixing ring 1-2 is connected to the connecting sleeve 1-1 through a thread. At the same time, the chuck is provided with a protective cover 7.

When the jaws need to be opened, the adjusting handle 3-1 is driven downward by an external mechanism, and the transmission gear 3-6 is further driven, and the guide transmission shaft 3-4 is further driven to move upward, and the clamping jaw opening seat 3-7 and the clutch separation seat 3-5 are further driven to move upward synchronously, so as to realize the opening of the jaws and the self-rotation stopping of the A-part, and vice versa, the closing of the jaws and the self-rotation operation of the A-part are realized. A compression spring 3-8 is arranged between the guide transmission shaft 3-4 and the fixed base 3-3, and the upper and lower ends of the guide transmission shaft 3-4 are provided with adjusting nuts 3-9, and the adjusting nuts 3-9 can set the distance between the clamping jaw opening seat 3-7 and the clutch separation seat 3-5, and the fixed base 3-3 is connected to the turntable of the A-part of the bottle making machine by screws.

The auxiliary compression spring 2-10 is connected with the auxiliary integral adjustment ring 2-3. The connecting sleeve 2-6 is provided with a fixed base 6. When the guide sleeve 2-5 moves downward, the transmission connecting rod 2-4 will drive the auxiliary chuck jaw 2-1 to close. A spring 2-2 is arranged in the middle of the transmission connecting rod 2-4. When the guide sleeve 2-5 moves upward, the transmission connecting rod 2-4 will return to its original position due to the action of the spring 2-2, thereby driving the auxiliary chuck jaw 2-1 to open. When it is necessary to adjust the size of the overall opening of the jaws, it can be achieved by adjusting the distance between the auxiliary integral adjustment ring 2-3 and the guide sleeve 2-5. The smaller the distance between the two, the larger the initial chuck jaw will open, and vice versa. A clutch 4 is arranged below the guide sleeve 2-5. When the self-rotation needs to be stopped, the clutch 4 is driven to move upward as a whole by the opening and closing of the A part and the self-rotation stop control device 3, thereby driving the auxiliary mechanism 2 and the clamping mechanism 1 to move upward together, so as to achieve the purpose of self-rotation stopping through the transmission separation between the self-rotation transmission gear 5 and the auxiliary mechanism 2 and the clamping mechanism 1. An axle pin is also arranged in the middle part of the transmission connecting rod 2-4 to connect with the spring 2-2, and an auxiliary roller 2-9 is also arranged at the other end of the transmission connecting rod 2-4, and the two are connected by an axle pin.
